Nugget freeform brown green American Turquoise

Royston is a district in Nevada consisting of three mines: Bunker Hill, Oscar Wehrend and the largest producer, Royal Blue. Royston turquoise is known for its beautiful colors ranging from deep forest green to rich, light blues set off by a heavy, brown matrix. The Royston district is still producing some turquoise of high quality but in limited supply.

Turquoise attains it’s color from the heavy metals in the ground where it forms.

Blue turquoise forms when there is copper present, which is the case with most Arizona turquoise.
Green turquoise forms when there is iron present, which is the case with most Nevada turquoise. Matrix is the host rock.
