black ringworm

Jade" fog" refers to the jade leather ( has weathered or oxidation ) and within the emerald (no weathering or oxidation ) or between the meat a semi oxidation micro weathered jadeite. In essence it is also part of the emerald, is from the weathering crust to weathered meat ( jade ) a transitional zone.

Fog color and the presence that jade impurities inside the number," a" is always new, transparency is good or bad and the clean degree. But it could not explain the is green, and the green.

Mist is white, yellow, red, gray, black. If the skin off, revealing deep white called fog, illustrates its impurities less " to" clean, have a certain permeability, if white mist under green, is pure green, and to match each other very valuable. They also illustrate the "kind" of old, most people like to bet the fog. Bai display in the iron and other elements are slowly oxidized,index difference but no serious oxidation.

If it is pure yellow fog, display of impurity elements, often appearing to Gao Cui, but sometimes because of iron ions produced by blue green tones may enter the lattice, also appears slightly blue green green. Red mist to illustrate its contained iron has serious oxidation, probably within the emerald appears gray"". Black fog mainly for a large number of impurities caused by oxidation, display jade more impurities, poor transparency.

Individual black mist will also appear in Gao Cui, but sometimes water is very poor. Not all emeralds have fog, some jade place produce jade no fog. In general can produce mist jade prolific in old plant new and old factory on the mine. Jade" ringworm"Jewelry jade means refers to the jade skin or internal saw a black black patches, band, or of various shapes and sizes, these black ringworm of the main mineral amphibole, orchid amphibole schist, chromite and some oxide composition, because these black mineral with color caused by chromium ions are distantly related, as well as black mineral one one tinea in chromite everfount release of the coloration of chromium ion, under appropriate conditions to green jade.

The close relationship between tinea and green. People called" black with green walk"," ringworm eat green .". But have ringworm does not necessarily have a green, green, do not necessarily have ringworm, tinea to see the production environment and time, and tinea is chromium element existence and other factors. Therefore, folk has" died" ringworm" and live ringworm ."

In the generation of jade process and many subsequent geological movement, many thermal fluid activity, a chromium release of geological environment, can make the jade to green. This is not necessarily a ringworm, tinea and green little relation. If the tinea symbiotic with jade, in favor of chromium element to release the geological condition, hydrothermal activity, tinea chromium within the continuous release of coloring, the local quality environmental change is not conducive to chromium release in color,Natural jade jewelry termination of coloration, can produce black with green walk phenomenon, called live tinea.

Generation after generation of jade," ringworm", no chromium release geological conditions resulting from the "death" of ringworm ringworm". According to the jade material on the green with ringworm, small structure and tumor, jade mineral with ringworm interspersed between, can accurately judge the living dead" ringworm" and" tinea". The relationship between tinea and green can be divided, ringworm and green mutual tolerance is not easy to separate, ringworm and green transition or boundaries clear, green and ringworm at a distance, all alone in the three. Sometimes the tinea next to "Songhua" display, it directs its has green, but the green number, shape can not judge.

Jade raw materials in the epidermis, and epidermal or deep or shallow color weathering, semi weathered sand shaped annular block like regular directional alignment phenomenon, that stone under local directional dynamic metamorphism and hydrothermal alteration of common strongly influence, make its interior has the potential to CR release from the green. Umbilical cord place does not necessarily have a green, there must be " preserved ", to illustrate their inner may have green. Scaly" kind of" old. Python with is generally parallel to the trend of green, green ( veins ) or green shapes, mostly for the primary fissure filling the chromium ions due to color.

Jade skin faintly visible some like moss as patches, plaques, a band called " the". Refers to the original raw materials jade on the green, has been eclipsed by weathering traces. According to the color, shape, direction, amount, density, can be inferred from its inner green shades, direction, size, shape and other. Observation to water in raw materials on careful study of.
