✦ UV Requirements:
A true filtered Longwave UV light (lw 365nm) is needed to see the strong fluorescence shown in the photos. Regular black lights will not show any fluorescence.
If your UV light isn’t as strong as the ones we used for photography, the fluorescence may appear dimmer or slightly different. Brightness and color intensity depend on the wattage and quality of your UV light.
✦ Specs:
• Dimensions: 2.5" x 1.25" x 1"
• Weight: 2.15 oz (61 g)

✦ Photographed using:
Lumencraft Convoy L21B-X4 365nm UV Flashlight with ZWB2 Filter. The pictures have not been retouched, what you see is real fluorescence.
✦ UV Safety Tips:
Always wear UV-blocking goggles and gloves (or sunscreen) when handling minerals under UV light since the light can be harmful to skin and eyes.
This makes a perfect gift for collectors, science lovers, or anyone into fluorescent minerals, geology, or curiosity displays. Feel free to reach out if you have questions about UV lights or collecting fluorescent minerals!
