Jim & Dawn Minette Collection Jim and Dawn Minette put together arguably the finest thumbnail mineral collection ever. We acquired the collection in 2008, but some fine specimens fell through the cracks and are still available. Keep in mind that Minette thumbnails often pushed the size envelope so they may not fit exactly into a 1 inch cube.

This fine chalcocite twin is purported to be from the Holden collection, one of the premier collections included in the Harvard museum. I say purportedly because there are no numbers on the specimen to match it with the Holden label. Regardless, this is an excellent chalcocite TN.
