INSIGHT 精辟洞见 GEMSWORLD | 25 | 2026 Treatment detection Identifying treatments is another primary concern of gemstone buyers. GIA is vigilant about any new developments in treatments that modify the appearance or properties of coloured gemstones. It reintroduced filler identification to its gemmological reports for emeralds at no additional cost in late 2024 and witnessed strong demand for the service throughout 2025. GIA will start charging for this report enhancement to identify filler material in emeralds in 2026. In an earlier interview, GIA Executive Vice President and Chief Laboratory and Research Officer Tom Moses said this strategic move was sparked by major US and European brands increasingly requesting for precise and up-to-date gemmological analysis. Meanwhile, well-known treatments such as the heating of rubies and sapphires continue to be prevalent in the market, said McClure. Clarity enhancement, which has typically been associated with emerald, is also appearing in many other coloured gemstones, most notably tourmaline. Challenges remain in detecting certain treatments. For instance, irradiation of some types of coloured gemstones still cannot be detected. “We are however constantly watching for new applications of existing treatments and the possibility of new methods. In 2023, we discovered cobalt diffusion being used to change the colour of spinel,” McClure remarked. Tech and education On the technology front, GIA is using machine learning and artificial intelligence (AI) to assist its skilled gemmologists and laboratory staff. For coloured stone services, the objective in using these advanced technologies is to increase efficiency by examining more gemstones and delivering results faster. “AI and machine learning are most effective as additions to our current methods for determining geographic origin. Experienced gemmologists review all recommendations from these systems before making a final determination,” noted McClure. “At present, complex origin determinations and treatment examinations are beyond the capabilities of AI or machine learning.” GIA’s commitment to the coloured stone sector extends to education. New modules on coloured gemstones and jewellery are being developed for the GIA NextGem programme that consists of short high-quality, on-demand training courses for retail associates to broaden the learning experience. McClure said, “We believe that our combination of extensive research, including our large coloured stone reference collection and comprehensive gemmological database, along with advanced tools and highly skilled gemmologists and laboratory staff, positions us to deliver services that meet the needs of the trade.” 近年，越来越多市场懂得欣赏宝石的魅力，GIA美 国宝石研究院因而聚焦发展彩色宝石相关的服 务。GIA彩色宝石服务部全球总监沙恩•麦克卢尔 (Shane McClure)表示，该机构全球实验室网络稳步扩展，收 到的彩色宝石检测要求数量显著上升。 优化服务 原产地鉴定与加工处理检测是现时两大需求，促使GIA 持续拓展这些服务。 在2025年，GIA推出了一项针对未经处理的翡翠和绿辉 石玉石的鉴定服务，用于确定翡翠是否产自缅甸或危地马 拉。及后于2026年1月1日起，将澳宝、橄榄石和翠榴石纳入 GIA原产地鉴定服务范围。 GIA原产地鉴定服务还涵盖亚历山大石、祖母绿、帕拉伊 巴碧玺、红尖晶石、红宝石及蓝宝石。 麦克卢尔表示：“这次服务扩展基于GIA实地宝石学家收 集的32,000份样本及深入的研究成果。GIA开展彩色宝石鉴 定服务已逾75年，我们各实验室的研究人员与宝石学家积 累了行业领先的专业知识。这份专业造诣，加上GIA数十年 来对研究的持续投入，是我们鉴定报告结果的坚实基础。” 此外，GIA的全套彩色宝石鉴定报告进行了重大升级。新 版报告的设计更精美，强调最关键的宝石学信息，并加强故 事叙述元素。GIA还修订了彩色宝石送检的重量分级及相关 费用标准。 加工处理检测 识别宝石的加工处理方式是宝石买家关心的另一个重 点。GIA始终密切关注任何可能改变彩色宝石外观或特性的 新式加工处理技术。 GIA于2024年末在祖母绿鉴定报告中重新引入填充物 鉴定服务，且不收取额外费用。在2025年，市场对这服务呈 现强劲需求。GIA表示，将于2026年起开始就这项服务收费。 在早前的采访中，GIA执行副总裁兼鉴定所和研发部首 席执行官汤姆‧摩西(Tom Moses)表示，该战略举措是为了 回应来自美国和欧洲的主流品牌，对精准且最新的宝石学 分析数据日渐攀升的需求。 麦克卢尔指出，加工处理宝石的方法仍然相当普遍，如 加热红宝石和蓝宝石。通常与祖母绿相关的净度优化处理， 现时也应用在许多其他彩色宝石中，特别是碧玺。 某些加工处理的检测仍面临挑战。例如，部分彩色宝石 的辐照处理至今无法被检测出来。 麦克卢尔续说：“我们密切留意现有加工处理技术的新 应用，以及崭新方法出现的可能性。在2023年，我们发现钴 扩散技术正被用于改变尖晶石的颜色。” 科技与教育 在技术领域，GIA正运用机器学习和人工智能(AI)辅助其 资深宝石学家及实验室人员开展工作。关于彩色宝石鉴定 服务，采用这些先进技术的目标在于通过检测更多宝石并 加速出具结果，以提升效率。 麦克卢尔指出：“AI与机器学习在辅助现有原产地鉴定 方法时效果最佳。经验丰富的宝石学家会审核系统所有建 议后作出最终判定。目前，复杂的原产地鉴定和加工处理检 测仍超出AI或机器学习的能力范围。” GIA对彩色宝石领域的投入延伸至教育领域。针对零售 从业人员的高质量随选培训课程“GIA NextGem”，将陆续新 增有关彩色宝石与珠宝的学习内容，拓展学员的学习体验。 麦克卢尔表示：“我们拥有庞大的彩色宝石参考藏品库 与全面的宝石学数据库，结合先进工具及高技能宝石学家 与实验室团队，这种综合研究实力使我们能够提供迎合行 业需求的专业服务。”
