Several base formulas are used to grow lab garnets, including YAG, GGG, LuAG, and GAGG. In terms of growth methods, lab garnets are produced using the Czochralski, HDSM, and Kyropoulos techniques. They can also be formed as polycrystalline ceramics, but we choose not to carry these due to their less clear appearance when cut into gemstones.
The majority of lab garnets are recycled from industrial materials. This includes some HDSM products and certain Czochralski-grown Yb:YAG garnets, specifically those mimicking "paraiba" colors, which are cultivated for the gem trade.
We categorize lab garnets into two main groups: the highly fluorescent lumogarnets and all other types.
