摘要

合成金刚石生产：高压、高温（HPHT）生长和化学气相沉积（CVD）生长。它还提供了用于鉴定这些实验室培育的钻石的主要宝石学和光谱特征。在过去的几年里，合成材料取得了许多进步：CVD技术的快速发展，生产10克拉以上HPHT合成材料的能力，以及HPHT生长的无色近战钻石的激增。图表的最左列集中展示近战大小的实验室培育钻石（小于0.2 ct的钻石）的特征，而最右列则展示了大型（大于5 ct）刻面钻石的照片和显微照片

Features of Synthetic Diamonds

synthetic diamond production: high-pressure, hightemperature (HPHT) growth and chemical vapor deposition (CVD) growth. It also provides the major gemological and spectroscopic features used to identify these lab-grown diamonds. The last few years have seen numerous advancements in synthetics: the rapid evolution in CVD technology, the ability to produce 10+ carat HPHT synthetics, and the proliferation of HPHT-grown colorless melee diamonds. The far left column of the chart focuses on features of melee-sized lab-grown diamonds (those less than 0.2 ct), while the far right column presents photos and photomicrographs of large (greater than 5 ct) faceted
