Bournonite on Galena with Sphalerite

This is one of those pieces that the more you look at it the finer it becomes. The subtle color and luster change between the metallic striated bournonites and the coated galenas with the druise of sphalerites makes for a top notch miniature. Ex Jim and Paula Wilson.
