泰国尖竹汶宝石交易小镇(Chanthaburi Thailand)

·尖竹汶(庄他武里)是泰国东部的一座只有5万居民的小镇,与柬埔寨交界。距首都曼谷245千米,是闻名遐迩的红宝石产地和红宝石加工及交易基地。尖竹汶曾经是刚玉红蓝宝石的重要产地。由于长年累月的开采挖掘,红宝石资源渐趋枯竭。那里的宝石商和工厂发展出了红宝石和蓝宝石的热处理技术,全世界的宝石商将红宝石和蓝宝石原石送到那里进行热处理和切磨加工。

Chanthaburi is a town in eastern Thailand located on the banks of the Chanthaburi River. This city of about 50,000 people is the main processing and trading center for colored gemstones in Southeast Asia.Around 80% of the world’s supply of rubies and sapphires passes through this town.
