MMX4 Bournonite, Sphalrite
Les Malines Mine, Saint-Laurent-le-Minier, Gard, Languedoc-Roussillon, France
6.0x 5.0x 4.6 cm

$375

An excellent FRENCH bournonite, hosting a complete "cogwheel" on matrix with sphalerite.  There is absolutely no damage to the piece, and the crystal even stands out a bit from the matrix (see image of backside, below the text)

Today, virtually all the bournonite on the market comes from one of two places: the Yaogangxian Mine in China, or Bolivia.  From time to time, expensive English classics also pop up, but these French specimens remain elusive.  This piece likely dates tot he 1990's, when the locality was reworked.

Better in person!
