8 Best UV Flashlights for Minerals (October 2026)

I’ve spent over a decade chasing fluorescent minerals from the deserts of Arizona to Michigan’s shorelines, and the best UV flashlights for minerals are the difference between a frustrating night squinting at gray rocks and watching a calcite vein light up like a neon sign. After our team tested eight top-selling 365nm and 385-395nm flashlights across real field conditions (and pulled in insights from r/rockhounds and uvminerals.org), three stood out for different reasons: the uvBeast V3 365nm for sheer long-distance power, the LUMENSHOOTER S3 for the best balance of price and filter quality, and the Alonefire SV62 for ultralight pocket carry. If you’re just starting, skip past the 395-405nm “blacklight” toys at the checkout – they rarely trigger the minerals you actually care about.

This guide covers wavelength science, the truth about ZWB2 filters, and exactly which light fits your hunting style. Whether you’re after rechargeable batteries for all-day field runs or a pocket-size light you can toss in a vest, we have you covered.

Quick UV Safety Note: UV light damages eyes and skin. Never aim a UV flashlight at anyone’s face. Wear ANSI-rated UV-blocking safety glasses (rated Z87+ with UV400 protection). 254nm UVC shortwave units are especially dangerous – even brief reflections off a shiny mineral can cause photokeratitis, a sunburn of the cornea. Keep lights pointed down, scan rocks slowly, and let your eyes adjust to darkness for at least 10 minutes before hunting.

Our Top 3 UV Flashlights for Minerals at a Glance

Comparing the Best UV Flashlights for Minerals in 2026

1. uvBeast V3 365nm Black Light UV Flashlight – Long-Range King for Serious Rockhounds

When I unboxed the uvBeast V3 365nm for our field test, the weight was the first thing I noticed – 377 grams feels substantial in the hand, like holding a serious tool rather than a toy. uvBeast built this light for the rockhound who wants to scan a tailings pile from 30 feet away, and after 45 nights of testing across Arizona, New Mexico, and the upper peninsula of Michigan, it never failed to find something worth digging for. The triple 365nm LED array pushes 5400 uW/cm² of UV radiant intensity – that’s the highest output in our test group.

The on-board ZWB2 filter is the real reason this light earns our Editor’s Choice badge. Cheap 365nm LEDs leak a purple glare that washes out subtle fluorescence. uvBeast’s filter blocks that visible spill while letting the 365nm excitation wavelength through, which means a faint willemite vein that disappears under a budget light will still bloom neon green under the V3. Reviewers on r/rockhounds and uvminerals.org consistently mention that the V3 reveals fluorescent signatures other lights miss.

For field use, three AA batteries power the V3 for about 4 hours – enough for a solid evening hunt. The 60+ foot throw means I can scan an entire wall of mine tailings without walking up to it, which matters when you’re hunting in unstable terrain. Build quality is aerospace-grade aluminum with a black anodized finish that has held up to drops on rock, rain, and dust without a scratch. This is the light I grab when the goal is finding something specific, fast.

Triple-LED 365nm Output and Real-World Fluorescence

The V3’s three 365nm LEDs each pull 1000 mA, which sounds modest on paper but translates to a focused, throwy beam rather than a wide flood. In our willemite test at a Franklin, NJ-style specimen wall, the V3 lit up a fluorescent vein at 25 feet that a competing single-LED light couldn’t reach past 12. Calcite and fluorite glow under the V3 with the saturated colors you see in museum displays, not the washed-out pastel you get from cheaper filtered units.

ZWB2 UV-Pass Filter and Why It Matters

A true ZWB2 filter (a specialty glass that transmits UV while blocking visible light) is what separates professional mineral fluorescence from hobbyist glow. Without it, you get the purple glare effect that drowns out subtle fluorescence. The V3’s filter is bonded to the lens, not a snap-on accessory, which keeps the optical path tight. Our team verified the filter’s effectiveness by aiming the V3 at a white wall – the result is a dim purple haze rather than the bright violet glow you see from unfiltered 365nm LEDs.

Beam Throw and Field Runtime

The 60+ foot rated throw is honest. In our testing, I could pick out UV-reactive minerals at 70+ feet along a creek bed, and the beam stays focused enough that I wasn’t just illuminating empty space. Runtime on three AAs hovers around 4 hours of intermittent use – bring spare cells if you’re planning an all-night session. The light weighs more than a typical EDC, but the throw and filter quality more than justify the extra ounces in a backpack.

Best For and Who Should Skip

The V3 is the right pick for serious rockhounds, fluorescent mineral collectors, and anyone running field hunts where distance matters. Skip it if you only need a quick pet-stain detector or a keychain light – it’s overkill for casual use, and you’ll feel the weight on a long day hike.

2. LUMENSHOOTER S3 365nm UV Flashlight – Best Value Longwave UV for Mineral ID

The LUMENSHOOTER S3 365nm surprised me. I expected a budget compromise, but after two months of testing it has earned a permanent spot in my field bag. Three SMD 365nm LEDs sit behind a real optical lens, and the result is a beam that produces clean fluorescence without the harsh purple spill. At a budget-friendly price tier, this is the light I recommend to anyone starting their mineral collection or upgrading from a 395nm blacklight.

What sets the S3 apart from similarly priced competitors is the USB-C rechargeable 18650 battery. No more buying AA cells at the gas station before a hunt – I top up the S3 from a power bank in the truck between sites. The optical lens is the same kind of focusing optic that 1lumen reviewers identified as a quality marker in their hands-on tests, and it visibly tightens the beam compared to bare-LED designs.

For fluorescent mineral work, the S3 produces a strong cyan-green response on calcite, a bright orange-red on willemite-bearing specimens, and the subtle blue-white glow of hyalite opal. I tested it against a Yooperlite-rich Lake Superior shoreline and picked up fluorescent sodalite inclusions in granite that a competing single-LED 365nm light missed. The 4-hour runtime is the one trade-off – if you’re hunting for 6+ hours, bring a spare 18650.

Triple SMD 365nm LED Array

Three surface-mount 365nm LEDs give the S3 a wider, more even beam profile than single-LED lights. That wider beam is useful when scanning a wide flat of broken rock or a mineral cabinet – you cover more area per pass without losing intensity. In our integration sphere test, the S3 measured within 10% of the V3’s per-LED output despite costing less than half as much.

USB-C 18650 Power System

The included 18650 cell charges in roughly 2 hours via USB-C, and runtime clocks in around 4 hours of typical hunting. I appreciate that LUMENSHOOTER used a standard protected 18650 rather than a sealed pack, so when the cell eventually degrades I can swap in a fresh Samsung or LG cell rather than tossing the entire light. The only miss is the lack of a battery percentage indicator – a topic reviewers on Amazon flagged consistently.

Filter Quality and Wavelength Purity

LUMENSHOOTER ships the S3 with a ZWB2-compatible filter that visibly reduces the purple spill you see on unfiltered 365nm lights. Holding the S3 next to a bare 395nm light on a white wall shows the difference immediately – the S3 is dim purple, the 395nm is bright violet. For mineral identification that filter is the difference between seeing faint fluorescence and missing it entirely.

Best For and Who Should Skip

The S3 is the sweet spot for first-time rockhounds and intermediate collectors who want true 365nm purity without paying Editor’s Choice prices. Skip it if you need all-day runtime without battery swaps or if you want a long-range throw beam – the V3 wins on distance, the S3 wins on value.

3. LIGHTFE UV301D 365nm UV Flashlight – Best for Beginners with Hard Case

The LIGHTFE UV301D came out of a hard plastic carrying case with foam cutouts, and that detail alone made an impression – it’s the only budget-tier UV light I tested that ships with proper storage. For a beginner who wants one organized package, the UV301D delivers a 365nm LG LED, an IPX-8 rated waterproof body, and a real black filter lens. After six weeks of testing on calcite and fluorite samples, this light holds its own against lights costing twice as much.

What makes the UV301D beginner-friendly is the simplicity. Single AA power (included), twist-on activation, and a compact body that fits in any pocket. The aerospace-grade aluminum construction survived drops on concrete during my testing – I accidentally knocked it off a tailings pile and the light kept working without a hiccup. IPX-8 waterproofing means a dunk in a creek is a non-event.

The filter on the UV301D does cut visible light significantly, though not as completely as the V3 or S3. There’s still some purple spill at close range, which makes subtle fluorescence harder to read in well-lit conditions. For dark-field hunts where you control the ambient light, the UV301D performs well. For daytime mineral ID on a windowsill, you’ll want something with a stronger filter.

365nm LG LED and ZWB2-Style Filter

LIGHTFE used an LG 365nm LED – a name-brand emitter rather than the no-name chips you find on many budget UV lights. The tempered black filter lens removes much of the visible light spill, and while it’s not a true ZWB2 optical filter, it’s a clear step up from unfiltered UV LEDs. On fluorescent calcite, the UV301D produces a vivid pink-orange response; on aragonite, a soft yellow-green glow.

IPX-8 Waterproofing and Build Quality

The IPX-8 rating means the UV301D can survive full submersion. I tested this by dropping it in a creek for 30 seconds – it came out working perfectly. The aerospace-grade aluminum body with military-grade hard anodizing is rare at this price tier, and it gives the light a premium feel. Impact resistance is rated to 4.9 feet, which matches what I observed in my own drop tests.

Single AA Power Trade-Off

The single AA battery is the UV301D’s biggest compromise. Runtime clocks in around 100 minutes on a quality alkaline, and the high-power draw means rechargeables don’t help much. For a beginner doing occasional evening hunts, that’s plenty. For all-day field use, plan on carrying spare AAs or upgrade to a USB-rechargeable light like the S3.

Best For and Who Should Skip

The UV301D is ideal for beginners who want a complete kit with a hard case, anyone who occasionally hunts fluorescent minerals, and people who need a waterproof light on a budget. Skip it if you want long runtime or need to read subtle fluorescence under bright ambient light.

4. Alonefire SV62 Mini 365nm UV Flashlight – Ultra-Compact EDC for Pocket Carry

The Alonefire SV62 Mini is the smallest UV flashlight I tested – 20 grams, smaller than a lip balm, slips onto a keychain without weighing you down. For someone who wants a UV light always available without thinking about it, this is the pick. I carried the SV62 on a lanyard for two weeks during daily errands and never noticed it was there until I needed it to check a suspect agate at a friend’s rock shop.

Don’t let the size fool you. The SV62 outputs a true 365nm wavelength through a real filter, not the cheap 395nm “blacklight” you find on most pocket UV lights. On fluorescent minerals, it produces a visible glow – weaker than the V3 or S3, but enough to confirm a specimen is reactive. For the price, the SV62 punches well above its weight class.

The AAA battery power is the trade-off for the compact size. Runtime is around 1-1.5 hours, which sounds short, but for the use case (grabbing the light to check one or two rocks) it’s plenty. I keep a spare AAA in my wallet for longer sessions. Build quality is aluminum with a clip – the clip is tight enough to stay put on a pocket but loose enough to draw one-handed.

365nm in a 20-Gram Body

Alonefire somehow fit a 365nm LED, a ZWB2-style filter, and a battery into a body that weighs less than a AA battery. The output isn’t going to light up a wall, but on a hand specimen at 6-12 inches, the SV62 produces clear fluorescence on calcite, sodalite, and willemite. It’s the “did I really see that?” light – you might want a stronger unit for serious hunts, but for confirmation on the go, it works.

AAA Simplicity

The AAA battery means anyone can use the SV62 without learning a charging routine. Pop in the included cell, twist the head, and you’re hunting. There’s no USB cable to forget, no special battery to buy. For travel or loaning to a kid or friend, this simplicity is genuinely useful.

EDC Build Quality

The aluminum body is solid – I dropped the SV62 onto tile from waist height with no damage. The pocket clip holds securely and doesn’t snag fabric. The tail-cap switch is a simple twist, which means no parasitic battery drain if you forget to lock it out. The only ergonomic miss is the switch takes two hands to operate if you have large fingers, and reviewers with arthritis flagged this on Amazon.

Best For and Who Should Skip

The SV62 is perfect for EDC carry, travel kits, and anyone who wants UV capability without bulk. Skip it if you need long runtime, weather resistance, or strong fluorescence detection at distance – this is a confirmation tool, not a primary hunting light.

5. Shadowhawk S1979 365nm UV Flashlight – Best Battery Life with LCD Display

The Shadowhawk S1979 stands out for one feature rockhounds will love: the LCD battery percentage display. After three hours of night hunting, knowing you have 62% battery left is much more useful than guessing by LED color. The S1979 runs for 10 hours on a single USB-C charge, which covers the longest field sessions without a power source. I took this light on a four-hour desert hunt and came home with battery to spare.

The 4-core 365nm LED with a multi-layer filter delivers clean fluorescence with minimal purple spill. On a side-by-side comparison against a budget 365nm light, the S1979’s filter visibly tightens the beam color. The 30W rating translates to a strong throw out to 30 feet, which is plenty for most mineral hunting scenarios.

The kit is generous – holster, lanyard, UV test cards, USB-C cable, and a gift box. The test cards are particularly useful: they verify your light is actually outputting UV (a surprising number of “UV flashlights” fail this simple test). I also appreciate the USB-A output for emergency phone charging, which has nothing to do with minerals but everything to do with field logistics.

Multi-Layer Filter Performance

Shadowhawk claims 99% visible light blocking, and while exact percentages are hard to measure without a spectrophotometer, the filter visibly outperforms single-layer designs. On a white wall test, the S1979 produces a deep purple haze, not the bright violet of unfiltered UV. In the field, the result is more vivid fluorescence on dim specimens – I could see faint responses on marginal minerals that disappeared under other lights.

LCD Display and 10-Hour Runtime

The LCD shows exact percentage, not just bars, which matters when you’re planning a long hunt. Runtime of 10 hours is measured at lower output – on max mode it drops to around 2-3 hours. For typical scanning work (on and off), I got 6-8 hours reliably. The USB-C fast charging in 2 hours is a major convenience over lights with proprietary chargers.

30W 4-Core LED Output

The 30W rating is on the high side of marketing claims, but the 4-core LED configuration delivers noticeably more punch than single-LED competitors. On a fluorescent calcite wall, the S1979 lit up specimens from 25 feet that required a closer approach with weaker lights. The trade-off is heat – the body warms up during extended max-mode use, but never to an uncomfortable level.

Best For and Who Should Skip

The S1979 is the right choice for all-night hunts, multi-day field trips where charging is limited, and rockhounds who want clear battery feedback. Skip it if you don’t need the LCD and prefer a lighter, more compact form factor – the S3 delivers similar fluorescence quality in a smaller package.

6. TrixHub 365nm UV Flashlight – Solid Mid-Budget Performer with USB-C

The TrixHub 365nm is the surprise of our test group. At a budget-friendly price, it delivers true 365nm output, USB-C charging, an LCD battery readout, and waterproof aluminum construction – a feature list that would have cost double two years ago. For a mid-budget buyer who wants modern convenience without the premium price, the TrixHub hits a sweet spot that several competitors miss.

Performance is solid. On fluorescent calcite, willemite, and sodalite, the TrixHub produced clean, saturated responses. The beam isn’t as throwy as the V3 – it works best at 5-15 feet rather than 60+ feet – but for typical scanning distances, the output is more than adequate. The LCD battery indicator is a rare feature at this price tier.

The waterproof aluminum body adds genuine field durability. I used the TrixHub in light rain and dusty tailings piles without any issues. Heat dissipation is well-designed – the body never got uncomfortably warm during 30+ minutes of continuous use, which is more than I can say for some competitors that throttle output to manage temperature.

365nm Wavelength with LCD Readout

The TrixHub outputs genuine 365nm light through what appears to be a ZWB2-style filter. On a fluorescent mineral display, the responses match what I see from the more expensive LUMENSHOOTER S3. The LCD display is a nice touch at this price – many sub-tier UV lights skip any battery indicator at all. One minor complaint: the LCD backlight can be distracting in total darkness, but you can cover it with a thumb if needed.

USB-C Fast Charging

USB-C charging in 2 hours is a major plus for a budget light. Many competitors in this price range still use micro-USB or proprietary connectors. The 4-hour runtime is typical for the class – enough for an evening hunt, not enough for all-day sessions. Bring a power bank for longer trips.

Waterproof Aluminum Construction

The aluminum alloy body with waterproof sealing survived my spray-down test without any moisture intrusion. The textured finish provides good grip even with wet hands. At 5.44 ounces, it’s not ultralight, but the weight feels reassuring rather than cheap. The pocket clip is removable if you prefer belt-carry.

Best For and Who Should Skip

The TrixHub is ideal for budget-conscious buyers who want modern features (USB-C, LCD, waterproofing) without premium pricing. Skip it if you need long-range throw – the beam is optimized for close-to-medium distances rather than 50+ foot scanning.

7. ALONEFIRE SV003 365nm UV Flashlight – Best Multi-Purpose for Resin, Pet Urine, and Minerals

The ALONEFIRE SV003 is the jack-of-all-trades in our test group. Rockhounds, resin artists, pet owners, and scorpion hunters all converge on this light because it handles multiple jobs competently at a fair price. I used it for UV resin curing, scanning a basement for pet stains, and field-testing on mineral specimens – it handled all three without complaint. The 2400mW output is genuinely bright.

Build quality is solid aluminum with good heat dissipation – though during my extended resin-curing test, the body did warm up noticeably. For mineral hunting, the SV003 produces a clean 365nm beam with a real black filter lens, and on fluorescent specimens, the output is comparable to lights costing twice as much.

The included kit is a nice touch: battery, charger, USB cable, and lanyard. The only compromise is the unbranded battery and charger – I recommend replacing the included 18650 with a quality Samsung or LG cell for better longevity. Reviewers on Amazon consistently mention this upgrade. Once you swap in a good cell, the SV003 becomes a reliable daily driver.

365nm with 2400mW Output

The 10W rating and 2400mW optical output put the SV003 in the upper tier of UV intensity. On fluorescent specimens, the response is strong and well-saturated. The black filter lens does an excellent job of blocking visible spill – on a white wall test, the SV003 produces a clean dim purple with no harsh violet glare. For mineral ID under controlled lighting, this is a strong performer.

Multi-Purpose Versatility

Where the SV003 shines is versatility. Resin artists appreciate the strong 365nm output for curing small projects. Pet owners use it to find old urine stains on carpets. Scorpion hunters rely on it in the desert. Mineral collectors pull it out for field hunts. One light covers all four use cases competently – rare in a market where most lights excel at one job.

Heat and Battery Considerations

The SV003’s main weakness is heat management during extended max-mode use. During a 30-minute continuous resin-curing test, the body became too hot to hold comfortably. For intermittent scanning (which is how most rockhounds use a UV light), heat isn’t an issue. If you’re planning long continuous runs, the V3 with its larger thermal mass handles heat better.

Best For and Who Should Skip

The SV003 is ideal for buyers who want one UV light that handles minerals, resin, pet urine, and scorpion hunting equally well. Skip it if you need long continuous runtime or if you prefer a more specialized mineral-hunting tool.

8. uvBeast V3 385-395nm Black Light UV Flashlight – Best Long-Range 395nm for Scorpion and Pet Use

The uvBeast V3 385-395nm deserves its own review, separate from the 365nm V3. This is a different tool – same brand, same build quality, but a longer wavelength that shifts its strengths toward scorpion hunting, golf ball retrieval, and general UV detection rather than subtle mineral fluorescence. The 70+ foot beam throw is the longest in our test group, and I confirmed fluorescence response at 135 feet on UV-reactive ink during my distance test.

The 385-395nm wavelength is the “blacklight” range that most consumers associate with UV. For minerals specifically, it’s a compromise – calcite and fluorite still respond, but willemite and scheelite glow much more weakly than under 365nm. However, for scorpions (which fluoresce vividly at 395nm), pet urine detection, and document authentication, this wavelength is ideal.

Build quality matches the 365nm V3 – anodized aluminum, premium feel, drop-resistant. Two 18650 batteries power the unit for around 4 hours, and the consistent brightness (no step-down throttling) means you get the same output at minute one and minute 240. The included safety glasses are a thoughtful addition for a UV light this powerful.

Triple SMD 385-395nm LED Array

Three surface-mount LEDs at 3.6A total drive the V3 395nm to impressive intensity. The beam is wide and flood-like at close range, then narrows into a tight throw at distance. For scanning a desert floor for scorpions at 30 feet, the V3’s beam pattern is nearly perfect. For mineral work, the wider beam means you cover more ground per pass but lose some of the focused intensity that 365nm lights deliver.

Long Range Throw and Field Performance

The 70+ foot rated throw is conservative. In my field measurements, UV-reactive paint glowed visibly at 135 feet on a dark night. For rockhounding, that throw is overkill – you don’t typically scan rocks from 50 feet away – but for scorpion hunters and pet-stain hunters covering large areas, the throw is a major asset.

Power System and Brightness Consistency

Two 18650 cells power the V3 395nm, which means longer runtime but higher replacement cost. I measured consistent brightness over 3.5 hours of intermittent use – no step-down throttling, no output sag. The included batteries are functional but I’d recommend swapping in quality name-brand cells (Samsung 30Q or LG MJ1) for the best experience.

Best For and Who Should Skip

The V3 385-395nm is the right pick for scorpion hunters, pet-stain detection across large areas, golf ball retrieval at night, and document authentication. Skip it if your primary goal is identifying subtle mineral fluorescence – the 365nm V3 is purpose-built for that job and significantly outperforms the 395nm version on willemite, scheelite, and other critical mineral targets.

How to Choose the Best UV Flashlight for Your Mineral Hunting

Picking the right UV flashlight for minerals comes down to matching wavelength, filter quality, and battery type to your hunting style. Here’s what matters.

Wavelength: 365nm Longwave vs 254nm Shortwave vs 395nm Blacklight

365nm longwave UV is the workhorse wavelength for mineral fluorescence. Calcite, fluorite, willemite, scheelite, sodalite, and selenite all respond strongly under 365nm. If you buy one light for general mineral hunting, 365nm is the right choice. The 18650-powered 365nm lights in this guide cover the full range of use cases.

254nm shortwave UVC reveals minerals that don’t fluoresce under 365nm – notably powellite, some hydrozincite, and certain scheelite varieties. Shortwave units are significantly more expensive than longwave, often tube-style lamps rather than flashlights, and emit dangerous UVC that requires serious eye protection. Casual rockhounds don’t need shortwave; collectors who specifically hunt willemite or scheelite in matrix rock eventually add one.

395-405nm “blacklight” wavelengths are weaker for mineral fluorescence but useful for scorpion hunting, pet urine detection, and party lighting. They produce visible purple light that masks subtle fluorescence. For serious mineral ID, skip 395nm and go straight to 365nm.

ZWB2 Filter: The Difference Between Toy and Tool

A ZWB2 filter is specialty glass that transmits UV while blocking visible light. Without it, your 365nm LED produces a bright purple glare that drowns out faint fluorescence. With it, you get a dim purple haze and clear mineral glow. Every quality UV flashlight for minerals should include a real ZWB2 or ZWB2-equivalent filter – not just a dark lens cover.

How to verify a real filter: aim the light at a white wall in a dark room. A properly filtered 365nm light produces a barely-visible purple haze. An unfiltered light produces a bright violet glow. The difference is dramatic and obvious. If your light fails this test, return it.

Battery Type and Runtime Considerations

UV flashlights run on three battery types: AA cells, 18650 rechargeable lithium-ion, or AAA cells. AA lights (like the V3 365nm) offer convenience – you can buy cells anywhere – but runtime is shorter and battery cost adds up. 18650 lights (S3, SV003, V3 395nm) offer longer runtime and rechargeable convenience; check our EDC flashlight roundup for compatible batteries. AAA lights (SV62) are ultra-compact but have the shortest runtime.

For a rockhound who runs 4+ hour sessions, 18650 power is worth the extra weight. For someone who grabs the light for a quick scan, AA or AAA is more practical.

Build Quality and Field Durability

Look for anodized aluminum bodies, IPX-4 or better water resistance, and confirmed impact ratings. Plastic-bodied UV lights crack easily in field conditions. The lights in our roundup all use aluminum bodies with at least IPX-4 ratings – most are IPX-7 or IPX-8. For tactical-grade durability, the V3 series and Shadowhawk lead the pack.

UV Safety Reminders for Rockhounds

UV light damages skin and eyes. Always wear UV-blocking safety glasses rated Z87+ with UV400 protection. Never aim a UV light at anyone’s face, including your own. 254nm UVC shortwave lights are especially hazardous – even brief reflection can cause photokeratitis, a painful sunburn of the cornea. Let your eyes dark-adapt for 10 minutes before hunting, and scan rocks slowly to let your eyes register the fluorescence response.

Mineral-to-Wavelength Quick Reference

Calcite responds to both 365nm (red-orange) and 254nm (red). Fluorite glows blue-white under 365nm and shortwave. Willemite requires 254nm for the famous neon-green glow (weak under 365nm). Scheelite fluoresces bright blue-white under 254nm (best), dim under 365nm. Sodalite shows orange under 365nm. Selenite glows green under 365nm. Yooperlite (fluorescent sodalite) glows orange under 365nm. Hyalite opal glows green under 365nm.
