GEMSWORLD | 23 | 2024 INSIGHT 精辟洞见 We are trying to follow the path taken by the LGD sector towards growth and success. Since LGDs are mainly produced in white, there is room for finer-quality green lab-grown gems such as our lab-grown emeralds. This gives us an opportunity to tap this market. Lo. “We expect the market to welcome our new stones with open arms since they closely resemble mined emeralds but come at a fraction of the cost and do not require any oiling or treatment,” he continued. The Biron technique of creating lab-grown emeralds using the hydrothermal growth process was developed in Australia in the 1980s and 1990s. The process has continually been refined and is now conducted in Hong Kong. Biron hydrothermal emeralds have the same gemmological composition as a natural emerald but typically have little or no inclusions due to its production process. Inter-Pacific’s new stones with a “jardin” appearance thus represent a significant technological breakthrough. New era in lab-grown gems Meanwhile, demand for Inter-Pacific’s classic lab-grown emeralds bearing the vivid colour saturation of beloved Colombian emeralds remains robust. An exceptionally strong market for such lab-grown emeralds is China, thanks to the country’s affinity for the colour green, disclosed Lo. “There is solid buyer interest in this category, specifically lab-grown stones of 5 carats and up. The retail price is well over US$100 per carat,” he added. Major jewellery houses actively using LGDs in their collections is also bolstering the appeal of lab-grown stones as go-to trendy options among today’s buyers. And this bodes well for lab-grown emeralds, according to Lo. “We are trying to follow the path taken by the LGD sector towards growth and success,” he said. “Since LGDs are mainly produced in white, there is room for finer-quality green lab-grown gems such as our lab-grown emeralds. This gives us an opportunity to tap this market.” 以中国香港为基地的泛洋控股有限公司表示，随着 买家日渐喜爱崭新的宝石和珠宝产品，实验室培 育祖母绿的发展前景一片明亮。 泛洋公司董事总经理卢益新透露，实验室培育祖母绿可 以跟随实验室培育钻石(LGD)的发展轨迹，满足市场对绿色 培育宝石不断增长的需求。 目前，该公司正在开发呈“花园”(jardin)特质的新型实验 室培育祖母绿，令视觉效果更自然，从而迎合此类宝石的激 增需求。卢益新指出，现在市面上的培育祖母绿往往像玻璃 般过于通透。 宝石学中的“花园”一词，普遍用来形容天然祖母绿内繁 密的内含物。 泛洋公司的新型“花园”实验室培育祖母绿原定于2023 年下半年正式问世，但生产过程比预期更具挑战性。 卢益新解释道：“采用水热法制造的新型Biron祖母绿，卖 点在于模仿天然宝石中的内含物。然而由于生产过程复杂 且困难，只有极少数的产品能够达到品质要求。” 他又补充，泛洋公司将需要更多时间来完善效果，并期 望在2024年下半年正式推出。宝石主要介乎于2克拉到5克 拉之间，并可限量生产最多10克拉的尺寸。新一批产品需要 动用更复杂的生产技术，因此价格比普通产品高。 泛洋公司新型Biron水热法合成祖母绿的目标客户，都 乐于采用外观自然的优质实验室培育宝石制作高级珠宝。 他表示：“我们的全新宝石产品与天然开采的祖母绿非常 类近，但成本相对甚低，而且不需要任何浸油或额外处理工 序，相信会大受市场欢迎。” Biron技术采用热液生长过程制造实验室培育祖母绿，在 1980和1990年代于澳大利亚开发后不断完善，培育工序目 前在香港地区进行。Biron水热法合成祖母绿具有与天然祖 母绿相同的宝石化学成分，但其生产过程往往令成品拥有 极少或缺乏内含物。因此，泛洋公司全新研制的“花园”祖母 绿，是技术上的重大突破。 培育宝石的新时代 与此同时，泛洋公司的经典实验室培育祖母绿呈现哥伦 比亚祖母绿的饱满色彩，至今需求仍然殷切。卢益新透露， 由于中国人特别钟情于碧绿色，所以一直是此类培育祖母 绿的强大市场。 “买家对这类实验室培育产品有着浓厚的兴趣，特别是 5克拉或以上的类别，零售价远超每克拉100美元的水平。” 他补充道。 各大珠宝品牌积极推出LGD钻石首饰，也提升了实验室 培育宝石在当今买家眼中的吸引力。卢益新指出，实验室培 育祖母绿也受惠于这股潮流。 “我们正在跟随LGD行业的步伐，迈向成功增长之路” 他说。“由于LGD产品主要为白钻，因此市场上还有空间吸纳 优质的绿色培育宝石。我们的实验室培育祖母绿必能把握 机遇开拓市场。”
