The larger crystal measures 6.5 x 3 x 2 cm in size, and the smaller is about 4.5 x 3 x 2 cm. These fat, 3-dimensional crystals tick out dramatically from a matrix of albite, and with schorl in the background for contrast. The matrix is actually a portion of an albite crystal, not just massive rock. There is a small bit of edge wear to each crystal's termination, which detracts only a tiny bit visually if you go looking, but for which the price is reduced quite a bit from the original price given to me in the "lot" group I bought. It has the most robust deep blue color I have seen before in an Erongo specimen, with a translucent and deeply colored body and a gemmy termination atop. The intense color, and large size, combined with luster and a contrasting schorl association, all conspire to make this a special pocket considered by those who saw them recently at the Denver show to be among the best aqua finds here in about a decade of quite sporadic aquamarine mining.
