north face down vest men Common market, posing jad

A Malay Jade: Jade, also known as Malaysia, Lu Song, etc. Is an artificial imitation of jade products, mainly minerals quartz, pure silica or quartz crystal melt by adding coloring agent made of. Hardness
6.5 ~ 7, the proportion of 2.65, the refractive index of 1.54 in 1988 in Thailand, Myanmar and Yunnan Province of China became popular along the border. Many people fall at the beginning,north face down vest men, some people go bankrupt Malay jade. A good market, to the late unscrupulous traders to green quartzite, Australian jade, Tanglin jade and jade green glass, all known as a Malay. Can accurately determine with the ########## eye.
Second, Shuimo child: China-Burma border often see white, transparent or translucent Overall color is white or gray, white and with fewer spots, uneven distribution, dim bluish hue. This jade in Yunnan called Its head looks like a good kind of jade ice, especially the floating orchid species. Shuimo sub main mineral component of albite and a small amount of pyroxene and amphibole minerals. It's color-causing material is arranged in a certain direction of actinolite, epidote. Blue flowers floating in the Observed with a magnifying glass does not significantly Tsui, the brain contains more stone or white cotton, very good head, this is a very important feature. Overall color is gray or white. Shuimo sub-5.5 to 6 stone hardness, specific gravity (2.57 - 2.64) than the proportion of Jade (3.32) is much smaller. Determination of refractive index of 1.52 to 1.54. Knocking them sound boring, not as good as Jade crisp. Carved with a hard mineral such as raw materials or semi-finished products, such as the use of crystal carved, Shuimo child can easily be scratched, jade is difficult to characterize.




three foam stains: produced in Myanmar border in Yunnan, a common gray-green, head of poor rock. It said the foam collapse. Shen Nong was made because of the color sheet jewelry. Foam collapse of the main components of sodium chromium mineral pyroxene, with minor jadeite, omphacite, chrome jadeite, glaucophane and so, in fact, satisfied chromium pyroxene. Transparency with which a certain sense was only known as Na Yu Hui Yu Shi chromium. Hardness of 5 to 6.5, the proportion of 4 to 3.17, the refractive index of 1.63 to 1.66.
four tumbler: grapes produced in the northern region of Myanmar, because names named. Green was banded, spotted, and patchy, the general transparency is better, a few poor. Major mineral water grossular, times for zoisite, vesuvianite and amphibole and so on. Deep purple color filter change as the main feature, in fact, water grossular Yu Shi. Hardness of 6.5 to 7, the proportion of 3.41 ~ 3.44, the refractive index of 1.71 to 1.72. Grape region also produced a kind of color filter also significantly purple jade, jade such transparency is better, blue or blue-green bluish, the main minerals are quartz, opal and chalcedony. Should actually be called jade quartz protein. Hardness 5.5, specific gravity 2.13, refractive index 1.45, and the water should be a strict distinction between grossular.
five, trapped on: produced in China-Burma border area, transparent to translucent, gray-blue or blue-gray color, were banded, ribbon. Main mineral composition of tremolite, actinolite, containing a small amount of chromite and so on. Hardness of 6, 2.96 - 3.02 specific gravity, refractive index 1.60 ~ 1.61. Actually nephrite.
