- Super dark specimens are very rare and prized specimens.
- Often so dark they must be back-lit to show their true color (as seen in the combined images).
- The dark color is caused by exposure to radiation during the crystal’s growth.
- As with any fluorite, you can wash it in warm soapy water and rinse with distilled water to reduce the chance of water spots on the surface.
- Can fade in sunlight! Do not display in direct sunlight or you can fade the rare color of the specimen.
- Do not use abrasive cleaners or soaps with alcohol! This can damage the crystals.
Locality of this piece: Locality of this piece is currently unknown, but similar dark specimens have been found in Mexico, Namibia, Illinois, and Kentucky.
Price range: The darker and more opaque the crystals are, the more expensive they become. Super dark specimens can be over $50 depending on the size and aesthetic looks of the crystals. Lighter specimens that are dark, but can see the true color in some areas will be much more affordable.
