Copper ("Spinel"-twins and crystals)

A fantastic toenail sized display specimen of fine crystallized and "Spinel"-twinned Copper from this wonderful discovery in Australia. This undamaged, showy, doubly terminated "floater" shows a marvelous combination of sharp, well-defined, euhedral crystals of Native Copper along with elongated, striated "Spinel"-twins. The piece is highlighted at the top by a wonderful dodecahedral crystal of Copper with both smooth well-formed positive faces and skeletal or "hoppered" negative faces. As you move down the length of the piece, you see the gorgeous blending of both crystal faces and twin lines to create and three-dimensional and show display specimen of these fine-looking Coppers. This is one of my favorite specimens in the lot that we purchased for its stylish and dramatic form along with the excellent overall quality. The Rocklands Mine (also known as the Rocklands Group Copper Project) is a large copper deposit in northwestern Queensland, Australia and wasn't known primarily for producing much in the way of specimens. We started to see some arborescent / dendritic specimens of Copper trickling out in 2017, but in 2019 there was a major discovery of significant and important CRYSTALLIZED Copper specimens! At the Tucson Show in 2020, we were fortunate to have a good friend who works at the mine and gave us first choice to hand select from a parcel that he brought especially for us. Specimen # CUAUS72014
