Boltwoodite, near Swakopmund, Namibia
description: 3 1/2" ac. Ex Prosper Williams collection By modern standards, this is not a very high quality specimen of boltwoodite. By 1970's standards, this was a very fine piece. It is accompanied by an old Prosper Williams label and the price of $150 which the specimen sold for in 1978 is marked on the label. The main appeal of this piece is its provenance and historical value.
