河南柘城，被称为中国钻石之都，虽然那里没有天然钻石矿，但近几年通过实验室培育出了人造钻石而声名鹊起。目前，柘城培育钻石年产量达1200万克 拉，产量已经占据全国60%以上份额。 培育钻石裸钻的市场价格根据品质不同，通常在2000元-4500元每克拉，价格大约只占天然钻石的1/5到1/10，培育钻石的品质主要取决于颜色、净度、切工 和重量。颜色越接近无色、杂质越少、切工越完美的培育钻石，品质会更加优异，价格也更高。 记者在当地最大的钻石生产厂，看到了生产培育钻石最主要的设备之一：六面顶压机，而车间里共计有600台设备正在同时运转。 六面顶压机在运转时会完全模拟天然钻石高温高压的生长环境。天然钻石生长时间需要亿万年，但在这里，收获一克拉左右的培育钻石最快仅需一到两周。 培育钻石的需求不断增长，上游配套生产企业也加快了脚步。一家金刚石材料企业专门生产传压密封介质，这是钻石培育过程中构成生长腔体必不可少的关 键辅助材料，共7个部件组成。这家企业一年能生产两千万套左右传压密封介质，产值超亿元。 柘城所在的商丘地区，本就是中国"超硬材料产业基地"，拥有生产工业金刚石的深厚技术基础。培育钻石实际上就是品质达到宝石级的"人造 ...
