tibetan turquoise

Prized by native cultures and used for trading for hundreds of years, a lot of turquoise is sourced - but not necessarily mined, due to a great deal of ancient trading - from Tibet, where it is highly revered as a symbol of the sky. Beads are given to Tibetan children, as they are believed to keep them from falling. Ranging from darker blues to green, this turquoise is generally threaded with dark matrix, giving a 'spiderweb' appearance. Cut from the original black host rock, there may be traces of staining from ancient iron ore. A conservative estimate for old trade beads is 300-500 years, but some may be older than 500 years given that the beads were used in trading since around 1000 B.C.
