Copper ("Spinel"-twin)

A beautiful "Spinel"-twinned Copper specimen from the Rocklands Mine in Australia. This doubly terminated, undamaged "floater" features a robust, sharp, well-formed elongated twin, which actually shows multiple planes of twinning, highlighted by beautiful repeating negative skeletal crystal face lines on both sides. The rich antique patina on the surface combined with the fantastic crystallization and form make it an eye-catching and high quality example of these fine quality Coppers.

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.
