high-grade jade cufflinks

She jade too have three basic colors of white, blue, emerald green, there are some transitional color, green white, gray, green beans, dark green, and so on. The Baiyu in the industry people legends She too Tsui game and Tian Baiyu. jade have the talk of Johnson's emerald cufflinks is extremely valuable, high-grade jade cufflinks.
Two. Hardness: Hardness is one of the important symbol of identification She too Tsui. The hardness of minerals resistant to other objects invasive mechanical properties. Usually the hardness of two types: the relative hardness or hardness, a carved hardness. The absolute hardness, also called the indentation hardness. First is to check out the singe refractive index of the diamond cufflinks.  To determine based on the mineral surface can withstand the weight. She too Tsui Mohs hardness of between 6.9 to 7.2, the different varieties slightly different. Generally speaking, white jade hardness slightly larger than jade. The jewelery industry in general hardness as the division of an important sign of gems and jade cufflinks. Gem hardness is generally 7.3 degrees above the Mohs jade cufflinks hardness generally in the Mohs' scale of 4 to 7.2 degrees, She too Tsui hardness, polishing, easy to save with some collectible value.
Density: Density is the weight per unit volume of jade cufflinks. She too Tsui weight determination of samples with a small weight, 2.65 to 2.85. Different varieties slightly different, white 2.85, green jade, 2.65, Jadeite 2.75. Transparency: Transparency is the jade cufflinks allows the degree of visible light through, and jade cufflinks light absorption strength of the mineralogy is generally divided into a transparent, translucent, slightly transparent, non-transparent four kinds. She too Tsui belonging to micro-transparent body, in the general enterprising degree, through the light, but not see through the object-image. Single refractive index of diamond cufflinks is decided by the nature of diamonds.   Luster: The luster is the ability of the light reflex of jade cufflinks. She too Tsui shiny is a shiny glass. This gloss is not strong, it is not weak, that is not the light of the crystal inspiration, there is no low-light texture of the wax soft and delicate, shiny can learn a lesson.
Hetian jade, actinolite, hornblende family composition. Is the main source of Chinese jade. Produced in the Kunlun Mountains foothills and the river bed. Hotan district-based. Its hard jade and delicate. Mineral aggregate produced in the alpine mountain jade, seed material produced from the riverbed. Divided into by color: jade, topaz, jasper, black jade, sapphire, jade sugar fine white jade immaculate, known as mutton fat jade.
