turquoise
Turquoise is a high-quality jade material. The ancients called it Bidianzi, Qinglanggan and so on. Europeans call it Turkish jade or Turkic jade. Turquoise is recognized as the birthstone of December at home and abroad, representing victory and success, and has the reputation of being the stone of success.
Turquoise has different colors because it contains different elements. Oxides are blue when they contain copper and green when they contain iron. Most of them are sky blue, light blue, green blue, green and light green. Uniform color, soft luster, no brown iron wire, the best quality.
Color is an important factor affecting the quality of turquoise. Turquoise products are colorful and deeply loved by people all over the world. In order to protect mineral resources, some places in China explicitly prohibit mining, so merchants import from abroad and then process turquoise in the mainland, and then sell their first batch of ornaments and handicrafts to other places. Besides Kashmir, Lhasa is currently the largest turquoise trading market in the world.
Turquoise is delicate and soft in texture, moderate in hardness and charming in color, but quite different in color, hardness and quality. Usually divided into four varieties, namely porcelain pine, pine, instant noodle pine and iron pine.
