Tourmaline is a mineral supergroup that includes gems with a wide range of chemical compositions. More than 40 recognized tourmaline species exist in all the colors of the rainbow. Tourmalines generally form elongated crystals with triangular cross sections, and they are often color zoned. This color zoning results from changes in the mineral solution when the tourmaline crystallizes. Treatment | Heating/DR Tourmaline is unique in that it has no laboratory-grown counterpart. Any tourmaline you see on the market (if it is indeed tourmaline) is natural. Tourmalines are occasionally treated, with pink tourmalines irradiated to increase their color saturation and blue and green stones undergoing low-temperature heat treatment to improve or lighten their colors. Such treatments are often undetectable and don’t typically affect a tourmaline’s inclusions. Fracture filling is generally the only treatment that leaves any visible evidence.
