Natural or synthetic?
To be able to evaluate a gemstone today, it is not only necessary to be able to see the difference between a synthetic and a natural gemstone, but also to recognize the treatment methods the stone was exposed to. (Over 95% of sapphires and rubies are heat treated to intensify the color and they are commercially traded). A great deal are also treated with chemicals and dyes that can make the stone less durable. There are large price differences between synthetic, heat-treated, untreated natural, and beryllium-treated gemstones.
