At 300 grams, this is perhaps my favorite of the larger pieces here as a "collector quality specimen" because it is very sharp, and complete all around except the bottom. It also has the best symmetry. 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.
