GEM COUNTRY USA - INFORMATION - GEMSTONE ENHANCEMENTS

It is common practice for the majority of manufactures to enhance gemstones for better color, clarity, or other reasons. Most of the gemstones we have are imported from over seas, purchased directly from huge importers, as well as liquidations & estates where we have no control over the cutting and treatment process. We are unaware of any specific treatment, if any, of most of our gemstones. Therefore please assume all gemstones sold by Gem Country USA are treated or enhanced in some way unless otherwise specifically stated.
