这是大颗 CVD 合成钻石检验的实验室笔记。

本文简单介绍了巴西 Feninjer 珠宝展的盛况。

Vincent Pardieu 讨论需求、处理和矿业。

We’re placing a remarkable resource—almost 80 years—of groundbreaking gemological knowledge at your fingertips.

CVD 工艺与天然钻石的形成有极大的差异。 在充满烃气体（通常是甲烷）和氢气的热混合气体的真空室中，施加极低压力，于是产生了钻石。

曼谷可能是泰国宝石产业的金融中心，但产业心脏位于尖竹汶府，大部分宝石仍在此切磨。

从以下方面探讨这一技术的有用性：缺陷和光谱特征映射，色彩来源的确定，以及如何鉴别合成钻石和经处理的小钻石。

满怀对五月 JCK Las Vegas Show（拉斯维加斯 JCK 珠宝展）的期待，钻石生产商们表示，自一月起，市场情绪已大幅提升，这在很大程度上归功于来自美国零售商的好于预期的订单。

学员们学习高科技制造和生产工具来设计和制作珠宝

In mid-2012, one of the international diamond grading laboratories in Antwerp reported undisclosed CVD synthetic diamonds, causing a stir in the diamond industry.

The stone owes all of its green color to these shallow radiation stains.

Recently, an unusual 0.94 ct Fancy yellow-brown emerald cut was submitted to GIA for a synthetic diamond grading report. It contained a cloud of black needle-like inclusions occurring along a plane and showed weak green transmission with fiber-optic illumination.

The New York laboratory recently tested a 2.16 ct CVD synthetic from Scio Diamond Technology Corp., the largest specimen GIA has seen so far.

The gemological and spectroscopic characteristics of these type IIa synthetic diamonds suggested that they experienced different growth and/or treatment histories.

Deep blue apatite with a cat’s-eye effect, however, is very rare.
