Pailin sapphire was one of the first "blood gemstones."
|The first stones ever to be treated with heat to improve their colours allegedly originated from the Pailin mines in Cambodia. Cambodia is famous for commercializing gem treatment.|

Sapphire mining was not the only type of digging that was carried on in Pailin. It is considered one of the most heavily landmined areas in the world.
