Synthetic rubies are the most problematic problem compared to artificially optimized rubies. The earliest synthetic ruby ​​was first made of alumina powder by a French chemist Wei Nuoyi. The synthetic ruby ​​has flooded the market. People not only use it to make some cheap decorative jewelry, but also use it as a natural ruby.
2, flux method
In 1963, Chatham Company of the United States used a flux method to synthesize a new synthetic ruby ​​called Chatham Ruby. These fluxing methods synthesize rubies, which are more similar in appearance to natural rubies and are therefore more deceptive. To identify the microscopic features between counterfeit rubies and natural rubies, it is very difficult for most ordinary investment collectors. Therefore, it is best to ask the relevant appraisal agencies for detailed appraisal.
3. Hydrothermal method
The hydrothermal synthesis of rubies is more difficult to identify than the flux synthesis of rubies. The most important identifying feature is still the presence of seed crystals; in addition, some "bread-like" inclusions can sometimes be seen; others have some micro-corrugated texture. If these features are not found, they can only rely on detailed measurements of larger, more sophisticated instruments such as infrared spectrometers and electron probes.
