What an eye-catching and fine quality specimen of this now classic material
as there is already associated Sphalerite on the reverse side that looks quite different from what’s on the front of the piece
A great quality specimen for somebody looking to own a rare and attractive "black" mineral
and the crystal habit is excessively rare in my experience with specimens from this mine
blocky Amazonite crystals with a light blue-green color
Copper ("Spinel"-twins and crystals) sulfosalt What an eye-catching and fineThis beautiful specimen of Native Copper from the Rocklands Mine hosts a wonderful combination of sharp, euhedral, crystals and elongated "Spinel" twins intergrown to create a display quality piece. Several fine quality, smooth, defined dodecahedral and octahedral crystals of Copper can be seen from all sides. They show both smooth well formed positive faces and skeletal or "hoppered" negative faces, but they are highlighted by elongated "Spinel"
