Artificial rubies are really gems. According to the definition of gemmology, synthetic gemstones refer to crystals or amorphous bodies that are completely or partially artificially manufactured. It has a known counterpart in nature, and its physical and chemical properties are basically the same as the corresponding natural jewelry and jade. Synthetic ruby is such a kind of gem, which is almost the same as natural ruby in composition, structure and properties, but it is artificially involved in the production process rather than naturally formed in nature.

1. In the national standard GB/T 16552-20 17 "Names of Jewelry and Jade", jewelry and jade are divided into natural jewelry and artificial products, among which synthetic gems belong to artificial products, corresponding to the existing gem varieties in nature. As a synthetic gem, synthetic ruby has the same physical and chemical properties and composition structure as natural ruby.

2. Therefore, the synthetic ruby is a real gem, but the artificial trace on it replaces the natural formation process. In the market, synthetic gems are sometimes called "artificial gem", but this does not change their essence as gems.
