First, the Malay Jade: Jade, also known as Malaysia, Lu Song Yu and so on. Is an artificial imitation of jade products, mainly of quartz, quartz crystals of pure quartz or coloring agent made of melted join. Hardness
6.5 ~ 7, the proportion of 2.65, refractive index 1.54. 1988 in Thailand, Myanmar and Yunnan Province of China became popular along the border. Many people fall at the beginning,belstaff jacken, some people go bankrupt Malay jade. Sell well in the latter part of unscrupulous traders in the green quartzite, Australian jade, jade and green glass all Tanglin called a Malay jade. Can accurately determine with the ########## eye.
Second, the foam sub: China-Burma border often see white, the transparent or translucent \Overall color is white or gray, with a few white spots and pigmentation, uneven distribution of dim bluish hue. This jade in Yunnan known as \It looks like a good ice kingfishers head, in particular, floating orchid species. Foam sub main mineral components of albite and a small amount of pyroxene and amphibole minerals. Its coloration material is arranged in a certain direction actinolite, epidote. Blue flower floating in the \Tsui observed with a magnifying glass no significant ######, with more naphtha or white cotton, very good head, this is a very important feature. Overall color is gray or white. Foam hardness of stone sub-5.5 ~ 6, specific gravity (2.57 ~ 2.64) than the proportion of Jade (3.32) is much smaller. Determination of the refractive index is 1.52 ~ 1.54. It sounds dull percussion, crisp as jade. Characterization of hard minerals such as the use of raw materials or semi-finished products, such as characterization with crystal,belstaff online, foam can easily be scratched son, jade is difficult to characterize.

three foam upon the stains: produced in Myanmar border in Yunnan, a common gray-green, head difference between the stones. It said the foam upon the collapse. Shen Nong was made because of the color sheet jewelry. Foam upon the collapse of the mineral chromium is satisfied that the main components of pyroxene, with minor jadeite, omphacite, chrome jadeite, glaucophane and so,outlet belstaff, in fact, satisfied that the chromium pyroxene. Which have a certain sense of transparency was only known as a jade-hui Yu Shi chrome satisfied. Hardness of 5 to 6.5, the proportion of 4 to 3.17, refractive index 1.63 ~ 1.66.
four tumbler: grapes produced in the northern region of Myanmar,belstaff sale, as its name names. Green was banded, spotted, and the plaque, the general transparency of the good, a few poor. Mineral water, primarily calcium-aluminum garnet, with minor zoisite, vesuvianite and amphibole and so on. Deep purple color filter under the main characteristics of change,belstaff uk, in fact, calcium-aluminum garnet water Yuk. Hardness of 6.5 to 7, the proportion of 3.41 ~ 3.44, refractive index 1.71 ~ 1.72. Grape region also produces a purple in color filter also significantly under the jade, jade such transparency is better, blue or blue-green side of blue, 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 water should be a strict distinction between Grossular.
five, trapped on: produced in the China-Burma border area, transparent to translucent, the color is gray or blue gray and banded, ribbon. Constitute the main mineral tremolite, actinolite, containing a small amount of chromite and so on. 6 hardness, specific gravity 2.96 ~ 3.02,belstaff blouson, refractive index 1.60 ~ 1.61. Actually jade.
