This is a classic example of what a "Spinel"-twinned Copper should look like. The piece has a beautiful mixture of the elongated form of the twin itself which plays beautifully against the smooth outer octahedral crystal faces. If you look to the center, you will see the concave "channels" that run the length of the specimen, these are essentially the contact planes where the crystals are twinned together. The piece is doubly terminated with no damage whatsoever, making it a pristine complete "floater"! A wonderful textbook example of these beautiful "Spinel"-twins. 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 # CUAUS72009
