Bournonite ("cogwheel") on matrix

Item Description

This is one of the more aesthetic specimens of Bournonite that I have offered from Bolivia in the auctions in months. This piece hosts an attractive, sharp, somewhat tabular, metallic, silvery-grey color, lustrous, "cogwheel"-shaped crystal group measuring 2.5 cm across sitting atop a matrix with Pyrite and minor associated micro Quartz. This specimen is from a find last year in Bolivia, and is certainly aesthetic not to mention in great condition overall. Valued at $500-$600 retail.
