Prismatic Bournonite in Quartz
Prismatic Bournonite in Quartz from Yaogangxian Wolfram Mine, Yizhang Co., Hunan Province, China
Collection Robert Lavinsky
Description A stunning Bournonite that is simply one of the "prettiest" examples I have seen. There are bigger, fatter, but few as sparkling and bright as this, with its contrasting white Quartz association. The crystal is 4.25 cm tall, and completely terminated. The termination is lustrous and as mirror bright as the body of the crystal. Slight crackling is present, as in many large examples of Chinese Bournonite, but the cracks do not go through, and are not very thick. The close embrace of the Quartz matrix preserved the crystal, in fact, when otherwise it would have fallen off and fallen apart (and hence, there are few good matrix Bournonites relative to loose crystals found here). Overall just a bright and lively specimen that is just way beyond the normal quality for here. It was hand-selected in China by travelling dealer Ken Roberts, years ago when the miners were robbing the pillars to mine more Bournonite in an old level of the mine (which led to a mine collapse and reported deaths in the early 2000's, sadly). It has since been in his personal collection of choice, generally sparkling and beautiful, Chinese miniatures and small cabinet pieces. Superb - hard to beat! Joe Budd Photos.
