$22.00
This bright shortwave fluorescent mineral specimen from the Hamburg mine in New Jersey features willemite, calcite, minor hydrozincite, and franklinite (non fluorescent).

✦ UV Requirements:
A true filtered Shortwave UV light (sw 254nm) 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: 3" x 1.75" x 1"
• Weight: 4.97 oz (141 g)
• Origin: Lang Shaft, Hamburg Mine, Franklin, New Jersey.
✦ Photographed using:
Engenious Designs SW (254nm) and Lumencraft longwave LW (365nm) UV flashlights. No photo editing or enhancement—what you see is real fluorescence. The pictures have not been retouched.
✦ 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!
