Thailand â—† Thailand is also a country with a long history of mining sapphire. The place of production is located in both Zhanburi and Kangsang La Buri.

The Boboli sapphire is mined from its underground alluvial deposits, and miners must find one carat of sapphire crystals from an average of 50 tons of alluvial soil. In the past 10 years, the Boboli mine has been over-exploited and almost exhausted. â—† Thai sapphire is very dark blue with a purple or gray hue. Sapphire usually has a distinct hexagonal ribbon, and there are no filament-like inclusions in the crystal. The density of the ribbon in the same crystal varies greatly.
