The color is good, and it's 15-20 lbs in weight. The clarity is decent. I inherited it and I have no use for it, so how much should I sell it for, and where?
The easiest way tot tell quartz and fluorite apart is based on their hardness'. Quartz has a hardness of 7, whereas Fluorite has a hardness of 4-5. Also, fluorite has cleavage, whereas quartz has no cleavage, but just breaks into conchoidal fracture.
