Copper Smithsonite 13.57 CT

RECOMMEND POINT
Rare copper-bearing smithsonite! Large size of 13 CT.

Rare color smithsonite over 13 CT.

Smithsonite is named after J. Smithson, who sponsored the founding of the Smithsonian Institution in Washington. It comes in a wide variety of colors, but not all of them can be found on the market, and some very rare colors exist.

Smithsonite belongs to the same family as calcite and aragonite, and inclusions are its fate. Since its crystal state is unstable, it is generally used as zinc ore.

Only a portion of it is used for jewelry, and most smithsonite circulating on the market is rough raw stone or drilled loose stones. Facet-cut crystals like this one are very rare.

Also, smithsonite comes in various colors depending on the content of chromium, cobalt, copper, manganese, and lead. When it contains copper (copper), it becomes blue or a strong bluish green.
This copper content is quite rare and is considered to be the most highly valued.

A large-sized smithsonite, an advanced collection stone.
