The English name of tourmaline comes from the ancient Sinhalese word Turmali, which means "mixed gem". The composition and color of tourmaline are very complicated. The international jewelry industry basically divides tourmaline into commercial varieties according to color. The brighter the color, the higher the value. Pay attention to color, transparency and purity when purchasing.
Place of production
Brazil is the best tourmaline in the world. The origin of Brazilian tourmaline is mainly concentrated in the state of Grasse in Minners. Tourmaline produced here is colorful. Up to now, more than 20 colors have been mined, including almost all the colors of tourmaline. Red tourmaline and green tourmaline produced in Brazil sell best, and they are the main mineral resources in Brazil, mostly occurring in the rich pegmatite veins in the local area. Paraiba, Brazil produces a blue-green tourmaline, which is expensive and rare, and the market is extremely hot, because it is named Paraiba tourmaline produced in Paraiba.
California is also one of the main producing areas of tourmaline. The dikes mined in the United States have weathered, and a large number of feldspar has become rock-free soil. Therefore, the mining method of tourmaline mine in the United States is mainly digging, which is easier than mining tourmaline in other producing areas.
Russia's Siberia, Madagascar, Sri Lanka and Myanmar also have tourmalines, but the texture is not as good as that of Brazil.
