This large, very euhedral davidite crystal measures a full 4.5 inches across and is SHARP. It is 817 grams. Most sides are complete, with the left side being a little contacted and the bottom only being broken off from matrix. It is an important, rare specimen from a find that I certainly had never even seen ONE piece from, and of museum size and display quality. This was locked away in a university study drawer since its discovery in the 1970s and only turned up recently to the market.
