An extraordinarily RICH specimen of bright silvery nagyagite in contrasting matrix, featuring unusual large "sheets" of nagyagite weaving in and out of the matrix (there's more on the backside as well). In fact, its the richest specimen of this rare Gold lead telluride that I have seen, myself, and its a pretty piece to boot. It is not the best around for crystal form, but for sheer quantity of gold telluride, this is amazing! Acquired in 1910 from Ward's Science Establishment. 6 x 5 x 3 cm
