Synthetic Forsterite and Synthetic Peridot

Kurt Nassau

Large crystals of chromium-containing synthetic forsterite are being commercially manufactured for use as a laser material. Considerable color variation is possible, and some of this material resembles peridot, with which it could be confused. Synthetic peridot has been grown, but only experimentally. This material closely resembles natural peridot and might be difficult to distinguish if it were to appear in the gem market.
