The word olivine comes from French Peridot. It is an ancient gemstone variety, chamado “the sun’s gem” nos tempos antigos. It can be used as a talisman, meaning that it can drive away evil like the sun. It is the birthstone of August, symbolizing peace, sucesso, and bringing good luck to the wearer.
The colors of olivine are yellow-green, green and brown-green. The most characteristic grass green of olivine is olive green, which is different from almost all green minerals. As gem-grade forsterite and chrysolite, its hue becomes deeper as the iron content increases. The color-causing element is iron.
High-quality olivine should be pure in color, preferably medium to dark yellow-green with uniform color, boa transparência, and no cracks and inclusions. Due to the development of olivine fissures, the finished product with large particles is rare, so the finished product of 3-10ct should have a higher value, and the finished olivine larger than 10ct is rare, so the price is high.
Olivine is identified based on the special grass green (slightly yellowish tint, also called olive green), the inclusion of water lily leaves, weak pleochroism, índice de refração, espectro de birrefringência e absorção. Due to the high birefringence, faceted edge double shadow lines can often be seen in faceted gems. Based on these characteristics, it is easy to distinguish it from other similar gems. Gemstones similar to olivine include green tourmaline (the pleochroism is obviously stronger than that of olivine, and the refractive index is significantly lower than that of olivine), green berkelite ((the refractive index and density are significantly higher than that of olivine, and the absorption spectrum is different), chromium Diopside (chromium absorption in the red zone) and chrysoberyl (refractive index and density are significantly higher than olivine).
my country’s Hebei and Jilin both produce good quality green to yellow-green olivine. The United States, Rússia, Mianmar, and Brazil also produce gem-quality peridot.
