At the forefront of this transformation is The Gem and Jewelry Institute of Thailand (Public Organization) or GIT, which is enhancing gemstone provenance and responsible business practices across the supply chain. “Provenance and traceability are no longer niche concerns confined to the luxury segment,” said Sumed Prasongpongchai, director general of GIT. “They have become fundamental to consumer trust, market access and long-term competitiveness.” Growing demand for traceability In recent years, GIT has seen an expanding spectrum of gemstones submitted for analysis. Rubies, sapphires, emeralds, fancy colour sapphires and jade continue to dominate, while there has been an uptick in client submissions of high-value spinels, garnets and Paraiba tourmalines. “Demand for identification, treatment detection and origin opinions on these stones has grown in parallel with market prices and consumer awareness,” said Prasongpongchai. GIT’s streamlined mini report, designed for everyday trading, has become its most widely used service due to its efficiency, cost-effectiveness, reliability and clear disclosures. Its full laboratory report with origin opinions, meanwhile, is highly sought after for top-quality gemstones, where provenance is key to market positioning. “The surge in these requests underscores that traceability and independent documentation are now regarded as fundamental requirements for accessing higherend segments of the market,” Prasongpongchai remarked. Central to GIT’s mission is the “Buy With Confidence” (BWC) project launched in 2018 to protect consumers and build trust in Thailand’s gem and jewellery industry.
