Fluorite Chunk -Green - Medium
Beautiful, high-quality chunk of green fluorite that has an interesting texture with visible crystal faces on all sides and vitreous luster. Unique true green color. This fluorite is hand-mined from a geologist friend of mine in New Mexico. Looks beautiful in a display cabinet, but don't leave it in the sun because sunlight will cause the color to fade over time. Some varieties are UV reactive, but I have not tested this specimen.
Fluorite is a favorite mineral of mine, as it can often be referred to as the most colorful mineral. It has a hardness of 4, cubic crystal structure and octahedral cleavage (perfect 4-plane cleavage). Fluorite is used as a source for making high-octane fuels, glass, ceramics, is used for smelting some metals, and is beautiful in ornamental stones and lapidary.
