NG12T9: This is a Spanish novelty because in the Los Amigos Mine Chrysocolla wasn't mentioned before. We should also mention that the appearance of this Chrysocolla is very attractive as it isn’t just a crust as usual but it has nice forms covering what seem to be crystals of Quartz and probably Chalcedony. These nice forms together with their great color, generate what is, in our opinion, the best Chrysocolla found in Spain and nearly as fine as the nicer ones from other countries.
As usual when we offer unusual things like this, we will send a copy of the analysis to the customer.
