Elbaite

ID: 4816
Add to OrderNot checked

A multicolored, beautifully terminated, lustrous single crystal of elbaite with gemmy areas and a pair of smaller crystals and minor mica attached on one side. The colors range from yellow to orange to a brownish red. It might be better to call this tourmaline, since there are dravites that come from this locality also that resemble this one, but the old labels said elbaite. An important crystal from this obscure locality!
