Famous for its vividly coloured blue Sapphires, the mines at Kanchanaburi and Bo Ploi (also spelt Bo Ploy) also produced the occasional grass green and sunflower yellow Sapphires, as well as their world famous black Spinel. The mines are situated in a jungle valley to the north west of Bangkok, the area is a very popular tourist spot and its bridge was featured in the war film “The Bridge on the River Kwai”. The main Sapphire mines are some twenty miles north of the main town. When the first discovery was made in 1918, within months thousands of artisanal miners started digging in an attempt to make their fortunes. Within a very short period, not surprisingly, the mines were all depleted.

The quality of Sapphire from the mine can vary from heavily zoned pieces, to pieces that are as open in colour and share a similar clarity to Ceylon Sapphires. In terms of tone, I have seen Bo Ploi Sapphires vary from 60% to 90%. In terms of saturation, Sapphires from the region can be amongst the best on the planet. Whilst Kashmir Sapphires are famed for their silky sleepy appearance, those from Kanchanaburi can sometimes look slightly milky.

Happy Bidding!!
