Scientific information: Johannite and Uranopilite are uranium-bearing sulfate minerals, both known for their intense fluorescence under ultraviolet light. This specimen’s green and yellow fluorescence makes it particularly desirable among collectors and mineralogists. The weak gamma radiation emitted is safe under standard handling practices.

Photos: The photos are taken under controlled lighting to ensure the natural colors of the specimen are represented accurately. Displaying the mineral in well-lit environments is recommended to appreciate its fluorescence and vibrant colors.

Warning: These minerals are slightly radioactive. Do not ingest or introduce them into your body. They are primarily alpha and gamma emitters. Alpha radiation is easily shielded by a sheet of paper. The specimen is sold with a plexiglass box that provides ample shielding.

It is important not to spend many hours per day near these minerals and to keep them in their protective box or in a well-ventilated area. They can be safely handled, but wash your hands immediately afterward. For any questions or requests, please contact us privately :)

Shipping: Shipping is typically processed the day after the order is placed, with tracking provided. Special care is taken in packaging to ensure safe delivery. Orders from the same customer will be grouped, and any excess shipping fees will be refunded in the package or through other agreed means.
