Copper ("Spinel"-twins and crystals)This beautiful specimen of Native Copper features a pleasing combination of defined "Spinel" twins and well formed crystals intergrown to create a display quality piece. The piece is highlighted at the top by a few wonderful dodecahedral crystals of Copper with smooth well formed faces sitting atop an elongated group of "Spinel" twins running the length of the specimen. One of the more "open" twins shows eye catching repeating skeletal or "hoppered"

as it would make a unique addition to your collection

this one is in great shape (especially for the size)

and the piece truly looks better in person as Ferberite is a difficult species to accurately photograph
