INCA STONE

Of the nearly 80 copper mines in Bolivia, only one comes out this material.
We have directly provided the mine owner
It is a new material in gemology and has no name, it is a naturally chalcedony colored by copper salts and inclusions of native copper. It is a very suitable very hard and resistant material for jewelry.
We are not aware that there is a similar material on the market therefore could also be considered a rare and gem collection.
We have called Inca stone, because it is from Bolivia and had been used in the antguedad
All these gems, have been carved in our workshop.
