Tourmaline, commonly known as gem -level electrical stone, English name is derived from the word "Turmali" in the ancient Sangha Luo, which means "mixed gemstone". In some historical documents in our country, it is called "Selenium", "Tourmaline", "Bixia", "Broken Evil Gold" and so on.
Thamanels are the customary names of my country's jewelry industry, and they belong to the electrical stone clan in minerals. The chemical molecular formula is (OH) 4, of which X is NA, K, CA, and R is a variety of metal ions. The type and content of R directly affect the color of tourmaline. It belongs to the three -party crystal system. The crystal is resurrected. There are a variety of colors, including color, rose red, pink, red, blue, green, yellow, brown and black, etc. Among them, the blue and fresh rose red as the top product. Glass luster, transparent to translucent, the discount rate is generally 1.624-1.644, the double refractive index is 0.018-0.040, and the color scattered 0.017. Strong poly color. Hardness is 7-7.5, density of 3.06-3.26 grams/cubic centimeter. No rheology, shell -shaped fracture. Tourmaline also has piezoelectricity and thermal power, which is also the origin of electrical stone names.
The common styles of jewelry processing Due to the different crystals of different gems, the shape and physical properties are especially optical. Style. In general, common styles are the following types: arc surface type arc surface type: also known as convex surface type or plain body type, its ornamental surface is a convex surface. According to the waist (shape of the waist), it can be further divided into round, olive, heart, rectangular, square, cross, pads, pituitary shape, etc. If according to its cross -section type, it can be divided into five types: single convex surface, dual -convex noodles, lentils, and hollow -up types, and concave surface -oriented types. The aspect type Facedate type: It is composed of a series of geometric planes that completely cover the surface of the gemstone. Polish it according to the appropriate angle. The gem can display the four optics such as body color, brightness, fire color, and shining. effect. Face -to -face type can be divided into diamond -type, step -type cargo, rose -type cargo, shearing (cross) type, and mixed -ending type. -beaded Peve type: Commonly used in low -grade gems and can be used for different jewelry. It can also be divided into types such as round beads, elliptical beads, flat balls, and rectangular beads. The alien is different: including the own type and random type, which can express the ever -changing natural form of gems.

arc surface type
arc surface type: also known as convex surface type or plain body type, its ornamental surface is a convex surface. According to the waist (shape of the waist), it can be further divided into round, olive, heart, rectangular, square, cross, pads, pituitary shape, etc. If according to its cross -section type, it can be divided into five types: single convex surface, dual -convex noodles, lentils, and hollow -up types, and concave surface -oriented types.
The aspect type
Facedate type: It is composed of a series of geometric planes that completely cover the surface of the gemstone. Polish it according to the appropriate angle. The gem can display the four optics such as body color, brightness, fire color, and shining. effect. Face -to -face type can be divided into diamond -type, step -type cargo, rose -type cargo, shearing (cross) type, and mixed -ending type.
-beaded
Peve type: Commonly used in low -grade gems and can be used for different jewelry. It can also be divided into types such as round beads, elliptical beads, flat balls, and rectangular beads.
