A superb thumbnail of bournonite with siderite from Bolivila. These days a decent amount of Bournonite is coming out of the Yaogangxian Mine in China, but specimens like this one from Bolivia are classics.
This is a top thumbnail, with a dark gray bournonite crystal aesthetically perched on a matrix shared by a few siderite disks.
