This specimen was photographed using a 36 watt shortwave ultraviolet lamp, and a longwave UV light. The pictures have not been retouched.
You can decorate your space with this accent display piece or add it to your personal mineral collection. This specimen was self collected at Sterling Hill mine in Ogdensburg, NJ.
*You will need a true filtered Shortwave UV light in order to see the fluorescence shown in the pictures. A Longwave lamp will show the sphalerite fluorescence, but the calcite and willemite will be less vibrant.
Shortwave lamps have a range of 200-280 nm.
Longwave lights have a spectrum of 315-400 nm and are also called UVA.
Please feel free to contact us if you have any questions about fluorescence or fluorescent lights.
*Please keep in mind that exposure to UV light is dangerous. We recommend the use of protective goggles and gloves (or wearing sunscreen in the hands) when handling minerals under UV light*
