Kanchanaburi Sapphire (Thailand)

The sleepy province of Kanchanburi, renowned for the Bridge Over The River Kwai, rests amongst the jungle clad valleys of Western Thailand.

Kanchanaburi’s Bo Ploi Sapphire mines were discovered in 1919, and today remain one of world’s premier sources of Blue Sapphires.

The Sapphires of Bo Ploi are mined from alluvial deposits spread over 320 Hectares.

The miners of Bo Ploi must unearth over 50 tons of alluvial soil to extract just 1 Carat of Sapphire crystal.

It takes 400 Carats of rough crystal to yield just 140 Carats of Kanchanburi Sapphire.

Kanchanaburi Sapphires possess stunning colors and clarity, and frequently offer better value than Ceylonese, Madagascan or Pailin Sapphires.

Sapphires have been mined from the Bo Ploi mines in the last ten years and are approaching depletion. This increasing rarity makes these Sapphires a must for any Jewellery collection.
