HKD, through its advanced gemological laboratory located in Bangkok, Thailand, the gemstone capital of the world, has built an extensive gemstone sample set and comprehensive scientific data. With this unique set of information, HKD is proud to launch its Gemstone Identification Report for Ruby, Sapphire and Emeralds. Key features for this report will be the gemstone's shape, measurments, weight, Refractive Index, colour grade, Gemstone Origin and any identifiyable treatments. See Report
