从“中国坯”到“中国钻” 河南发力打造培育钻石全产业链
Zhong Guo Xin Wen Wang· 2025-08-23 02:18
中新网郑州8月23日电 "从一块钻石毛坯打磨成圆形、方形裸钻,到如今的四叶草、元宝、生肖等各类 款式,不断精进的切割打磨技术让培育钻石的形态有了更多可能。"近日,在位于河南郑州的河南璨然 珠宝有限公司切磨研发中心,从业20余年的钻石切磨师李来锋如是说。 中国是全球最大的培育钻石毛坯生产国,生产能力占全球市场的80%,河南产能占据全国80%以上。其 根源在于该省是培育钻石原材料金刚石的核心主产区。故而,业界有着"世界金刚石看中国,中国金刚 石看河南"之说。 "金刚石的供应作为培育钻石产业链的上游部分,在河南具有显著的产能优势,但中下游环节却存在着 一定短板。"河南省培育钻石交易中心首席运营官陈耿介绍,从钻石毛坯到一颗钻石的璀璨问世,最关 键工序就是切磨师的精细雕琢。然而,国内在钻石切磨这一中游环节较为薄弱,下游销售也大多分布于 海外,这些问题都制约着行业的长足发展。 为了推动培育钻石产业链上、中、下游协同发展,近年来,河南在科创资源、平台建设、人才集聚等方 面加快布局,并将超硬材料产业链作为该省重点培育的28条产业链之首,以推动超硬材料产业优势再 造,发力延链、补链、强链。 作为国内唯一获批的国家超硬材料特色产 ...
