Yttriumaluminate - Reference Information
| Yttrium aluminum garnet (YAG) | Yttrium aluminum garnet (YAG) belongs to a group of specially developed materials. Since the mid-20th century, it has been used in quantum electronics equipment and laser technology. Yttrium aluminum garnet is Y3Al2(AlO4)3 oxide with a cubic crystal structure of natural garnet. Therefore, YAG is only called a synthetic garnet. YAG's hardness and density are greater than natural garnet, and it soon became popular in the jewelry market. With its high dispersion and refractive index, the colorless YAG was once used to imitate diamonds. However, after the advent of cheaper cubic zirconia, YAG soon lost its popularity. However, the fashion trend of synthetic gemstones in the jewelry market has been changing, and now buyers are looking for more interesting, bright, beautiful and uncommon materials with excellent optical properties. Therefore, RusGems began to continue to produce colored synthetic garnets. The most popular garnet is mint green, which corresponds to the top colors of natural green garnet shafley stone and bright yellow, but without any natural analogs.
