INSIGHT 精辟洞见 GEMSWORLD | 27 | 2026 Each certified item under the BWC project comes with a GIT Gem and Jewelry Identification Report and a QR Code that allows consumers to instantly verify the authenticity of their purchases. In the fiscal year 2024, GIT issued more than 14,500 reports. Addressing new treatment challenges Alongside identification and origin services, GIT is witnessing rising demand for testing related to treatment disclosure. Advanced analyses now focus on detecting heat treatment, lattice diffusion, clarity enhancement in corundum and detailed characterisation of impregnation and filling in other coloured stones. GIT’s research teams continuously track emerging treatments through global collaborations and participation in international gemmological conferences. Of particular concern are low-temperature and multi-step diffusion treatments that may evade standard detection methods. “The long-term stability of colour in treated gemstones, particularly where new or complex treatment routes are used, is a recurring question from our clients,” Prasongpongchai explained. “Effective communication of the gems’ nature, stability and implications in a way that supports transparent trade and protects consumer confidence is essential. Our role is to provide science-based guidance to our clients.” GIT's gem testing protocols are aligned with international standards, including ISO/IEC 17025, the World Jewellery Confederation (CIBJO) and the Laboratory Manual Harmonisation Committee (LMHC). Responsible and traceable supply chain GIT is also taking a holistic approach to responsible sourcing under its “Thailand Towards a World Sustainable Gem and Jewelry Hub” initiative. In 2025, it made significant strides in implementing global Environmental, Social, Governance (ESG) standards in the Thai gem and jewellery industry. “One of our major achievements has been the adoption of the Responsible Jewellery Council’s Code of Practices,” said Prasongpongchai. “This has elevated Thai small and medium-sized enterprises in the coloured stone and jewellery manufacturing sectors to align with international ethical standards.” GIT also introduced practical tools such as Carbon Footprint for Organization (CFO) assessments to help manufacturers measure and mitigate environmental impacts. This year, the institute plans to roll out the GIT Due Diligence Standard (GIT‑3001) as a national benchmark for jewellery supply chains, reinforcing Thailand’s commitment to integrity. “Our vision is that every coloured stone processed in Thailand can be traced – from cutting centres in Chanthaburi to export destinations – backed by verifiable credentials of sustainability and transparency while showcasing exceptional Thai craftsmanship,” said Prasongpongchai. 泰国珠宝行业在彩色宝石领域方面举世闻名，现正 迈进可追溯性的新时代。带领这场变革的泰国宝 石与珠宝研究院(又称“GIT”)属公共机构，一直致 力提升宝石溯源，并在整个供应链中推行负责任的商业实践。 GIT总干事Sumed Prasongpongchai表示：“产地溯源已 不再是奢侈品领域的小众议题，而是维系消费者信任、开拓 市场及保持长期竞争力的基石。” 可追溯性的需求上升 近年来，GIT收到的待检宝石种类越来越丰富。红宝石、 蓝宝石、祖母绿、彩蓝宝石和翡翠仍占主导地位，而高价值 尖晶石、石榴石和帕拉伊巴碧玺的送检量也呈现上升趋势。 Prasongpongchai说：“随着市场价格上涨和消费者意识 提高，对这些宝石的鉴定、加工处理检测及原产地证明的需 求同步增长。”GIT为日常交易设计的精简版迷你报告，因其 高效、合乎成本效益、可靠且信息披露清晰，已成为最广泛 使用的服务。与此同时，其包含原产地证明的完整实验室报 告，在顶级宝石范畴备受追捧，因为这些宝石的市场定位关 键取决于产地溯源。他认为：“这类需求激增，表明可追溯性 与独立认证文件已成为进入高端市场的基本门槛。” GIT于2018年启动“放心购买”(BWC)计划，旨在实践其 使命——保护消费者权益，提升泰国宝石及珠宝行业的诚信。 在BWC计划下，每件经认证的商品均附有GIT宝石及珠 宝鉴定报告及二维码，消费者可即时验证所购商品的真实 性。2024财年期内，GIT共出具鉴定报告逾14,500份。 应对新处理技术挑战 除宝石鉴定与原产地证明服务外，GIT也留意到披露加 工处理信息等相关检测的需求，同样呈上升趋势。先进分析 技术现聚焦于检测刚玉的热处理、晶格扩散、净度优化，以 及其他彩色宝石浸渍与填充技术的精细特征。 GIT研究团队通过全球业界协作及参与国际宝石学会 议，持续追踪新兴处理技术。当中，低温处理与多步扩散处 理尤为值得关注，这些技术可能规避标准检测方法。 Prasongpongchai说：“客户经常询问的问题就是：经过 处理的宝石颜色能否长期保持稳定，特别是采用新式或复 杂加工处理技术的宝石。因此，为了支持透明贸易且维护消 费者信心，有效传达宝石的天然特性、稳定性及相关影响非 常重要。而我们的职责，就是为客户提供基于科学的指导。” GIT的宝石检测规程符合国际标准，包括ISO/IEC 17025、 国际珠宝首饰联合会(CIBJO)及实验室手册协调委员会 (LMHC)的规范。 负责任且可追溯的供应链 除了实验室检测，GIT正通过“泰国迈向全球可持续宝 石及珠宝中心”计划，采取全面策略以推进负责任采购。于 2025年，泰国宝石及珠宝行业在落实全球环境、社会与治理 (ESG)标准方面取得重大进展。 Prasongpongchai表示：“我们最重要的成就之一，就是采 纳了责任珠宝业委员会的《实践准则》(Code of Practices)。 这使泰国彩色宝石和珠宝制造业的中小型企业，得以提升 至符合国际道德标准的水平。” GIT还推出了组织碳足迹评估(Carbon Footprint for Organization)等实用工具，协助制造商计算并减轻生产过程 对环境所造成的影响。 今年，该研究所计划推出GIT尽职调查标准(GIT-3001)， 作为珠宝供应链的国家基准，以加强泰国对诚信的承诺。 Prasongpongchai说：“我们的愿景是希望每颗在泰国加 工的彩色宝石都能实现全过程溯源——从尖竹汶府的切割 中心到出口目的地，都具备可持续发展及透明度的认证证 明，同时展现泰国精湛的工艺水平。”
