Gemstone of the Week- Turquoise
So how does turquoise get its dramatic colors? It's mostly from copper compounds (the blue) or some iron compounds (the green). Dark brown or black limonite forms the characteristic veining one sees in turquoise.
Turquoise is mined in various places in the world, mostly dry areas, the American SW, China, the Middle East, and was one of the first minerals to be mined and used in jewelry, so it has had a long, rich history.
