GIA美国宝石研究院通过加强透明度和保护消费者战略，一直处于实验室 培育钻石生产进步的前沿。 GIA: Ahead of the curve in LGD detection and testing 随着实验室培育钻石(LGD)以前所未有的数量涌入 市场，GIA美国宝石研究院正进一步增强其LGD 分级和鉴定能力，以巩固消费者的信任和信心。 GIA执行副总裁兼鉴定所和研发部首席执行官Tom Moses透露，他们的目标是增加市場上附带GIA报告的实验 室培育钻石的数量。 “我们的报告设计集中在消费者和零售商认为最重要 的信息——4C和钻石是天然还是实验室培育的，”Moses说。 2023年1月，GIA推出了更新及更经济的实验室培育钻石 报告——Dossier，此优化版报告报告删除了后期生长处理培 育类型选项，内容更精简，费用更经济，而所有重要数据都 齐全。同时，GIA为天然钻石和LGD而设的AGS Ideal Report， 则可测量和评估钻石的光性能表现、比例和修饰（包括对称 性和打磨）。 LGD发展 Moses解释培育技术不断改进，让买家现在可选择不同 尺寸、颜色和质量的LGD，款式林林总总。他补充说，“虽然有 这些发展，但天然钻石和LGD截然不同的形成方式，让GIA能 够百分百把它们区分出来。” 凭借过去数十年的研究，GIA的宝石学家和科学家采用 先进仪器以检查和分析LGD。这使GIA能够领先任何LGD生 产和鉴定方面的新趋势或发现。 LGD的未来 消费者对LGD作为天然钻石之外的另一选择的接受程度 与日俱增，并正在推动市场，但适当地披露LGD的资料对于 他们做出明智的购买决定是至关重要的。 关键在于选择附有由信誉良好的鉴定所，Moses评论道。 他补充说：“随着产量增加，LGD将跟随其他人造宝石的发展。 具创意的珠宝商会找更多方法把它们应用在设计中。最近， 我们留意到LGD的培育质量正在上升，而生产成本则下降。” With an unprecedented influx of lab-grown diamonds (LGDs) in the market, the Gemological Institute of America (GIA) is further augmenting its LGD grading and identification capabilities to better protect consumer trust and confidence. The goal is to increase the number of LGDs offered in the trade that come with GIA reports, revealed Tom Moses, executive vice president of GIA. “We tailor our reports to focus on the information that consumers and retailers find most important – the 4Cs and whether the diamond is natural or laboratory-grown,” continued Moses. In January 2023, the institute introduced a lower-cost Laboratory-Grown Diamond Report-Dossier, which is a revised version of the report that no longer includes the growth method or post-growth treatments, thereby reducing fees. Meanwhile, GIA’s AGS Ideal Report, which is available for natural diamonds and LGDs, measures and assesses the performance, proportions and finish – including symmetry and polish – of a diamond. LGD developments Citing continuous improvements in growth technology, Moses explained that LGDs are now available in a broader variety of sizes, colours and qualities that buyers can choose from. He added, “Even with these advances, the vastly different ways in which natural and LGDs form allow GIA to differentiate them with 100 per cent certainty.” GIA gemmologists and scientists employ advanced instrumentation, backed by decades of research, to examine and analyse LGDs. This allows GIA to stay ahead of any new trends or discoveries in LGD production and identification. Future of LGDs Wider acceptance of LGDs as natural diamond alternatives is fuelling sales in the market but proper disclosure is critical for consumers to make informed buying decisions. The key is choosing a gemstone that comes with a report from reputable laboratories such as GIA, remarked Moses. He added, “LGDs will follow the path of other manmade gems as volumes grow, and creative jewellers find more ways to use them in designs. Recently, we have seen both an improvement in growth quality and a decrease in the cost to produce LGDs.” 引领LGD检测和测试趋势
