Jewelry Glossary

A natural, semi-precious stone found in the desert. The brown or grey streaks in turquoise are caused by the matrix, or "mother" stone, from which the turquoise is mined. Interesting and intricate patterns are considered to add beauty to the stone. Persian turquoise is the only type of turquoise that usually does not have a matrix. Modern turquoise "stones" that appear very shiny and absolutely flawless are probably manufactured and of less value. Genuine turquoise can appear in colors ranging from sky blue to green.
