How is the turquoise hardness?
Turquoise is a high-quality jade material. It was called the jewel of heaven in the Qing Dynasty in China. How about the turquoise hardness?
The turquoise texture is delicate and soft, the hardness is moderate, the color is delicate and feminine, but the color, hardness and quality are quite different. The four varieties have different turquoise hardnesses.
Green pine: color from blue green to bean green, hardness is 4.5~5.5, slightly lower than porcelain pine. It is a medium quality turquoise.
Porcelain pine: It is the hardest turquoise in texture and has a hardness of 5.5~6. Because the fracture is similar to the shell shape, the polished texture after polishing is very similar to porcelain, hence the name. Usually the color is pure sky blue, which is the best in turquoise.
Pinus sylvestris: There are black limonite veins in the turquoise which are distributed in a network, making the blue or green turquoise appear as a turquoise species with black turtles, nets or veins. . The limonite veins on it are called "iron wires". The iron wire is slender, the bond is firm, the quality is hard, and it is integrated with the turquoise stone, so that the pine stone has a natural pattern like the ink line, which is beautiful and unique. Turquoise with beautiful spider webs can also be a good product. However, if the netting is composed of clayy fine veins, it is called mudline turquoise. Mudstone is not firmly cemented and has a soft texture, which is basically useless.
Foaming: Also known as the surface pine, it is light blue to moon white, the hardness is below 4.5, and can be scored with a knife. Because this turquoise is soft and loose, only a large piece has a use value, which is the finest quality of turquoise. However, in today's increasingly scarce turquoise raw materials, artificial treatment methods such as injection molding, wax injection and dyeing are often used to improve the quality and appearance, and thus "waste utilization".
