Bournonite (good quality)

Item Description

This specimen was collected in 2010, and it one of the best single Bournonite crystals from Machacamarca that we've offered in the auctions in a while. This mine is one of the most exciting Bolivian localities of the last 10 years. This piece a fully-crystallized, very good sized, attractive, fairly thick, tabular, metallic, lustrous, silvery-grey color, semi "cogwheel"-shaped crystal. The piece is very aesthetic, and the Bournonite crystal is virtually complete all the way around. Certainly one of the best from the 2010 find that I have handled. The piece looks repaired, but it is in fact complete and not glued together. There is actually only one spot on the bottom corner of the piece that would count as damage, but the rest is completely natural. For the quality, these new specimens have created a lot of excitement, so much so that one of the best pieces was featured on the cover of the March/April 2009 Issue of the Mineralogical Record! This piece is from the same mine and certainly could have been found near the cover piece. Bournonite is rarely seen in crystals this size from any locality in the world. Valued at $1800 for the size and attractive form
