Advanced Emerald Identification and Evaluation
Gemstones are created by nature, and they are usually imperfect owing to their innate characteristics and growth environment. This is especially true for rubies. In the gem market, various treatment methods have been reported applied to rubies with poor color or low clarity, for example, heating, lead-glass filling, organic filling, and beryllium diffusion, which are all common treatments applied to rubies. What is the difference in stability of rubies treated by these methods? This paper will elaborate on this.
