I think it can, but I've never seen fluorite with that fracture and structure before.ragi wrote:does fluroite even get that pinkish red color

Taken from my notes/http://www.minerals.net/mineral/fluorite.aspx:
It is one of the most varied colored minerals in the mineral kingdom
That was what I used when (hopefully) ID'ing the mineral.Fluorite has interesting cleavage habits. The perfect cleavage parallel to the octahedral faces can sometimes be peeled off to smooth out a crystal into a perfect octahedron. Many crystals, especially larger ones, have their edges or sections chipped off because of the cleavage.

ulexite. It exhibits the internal reflection of light along its crystal axis, like a fiber optic cable.
