We have the good luck sometimes of buying from one-off sources. And this Copper crystal has grown in a milky Quartz matrix. It came from a retired Australian geologer’s private collection. The only other place I have seen pieces like this specimen are in museums. He unfortunately lost his notes. I assume from it is from Australia because most of his collection was. The other indicators was the quality of the quartz.
This specimen clearly shows the delicate copper which has grown in a leaf shape. This is a piece for another geological collector and needs to be placed in a cabinet. It is not really for a metaphysical person as it is too delicate to be moved around.
