Malaysian jade is not a natural jade, but a dyed quartzite formed by melting timely crystals and adding dyes. ? Although the name has the word Malaysia, it has nothing to do with Malaysia, not a Malaysian. ?

Malaysian jade is a kind of artificial seasonable glass with devitrification. It is bright green or different shades of green, but it will gradually become blue and white over time. Stone flowers, which often contain dispersed small bubbles, have the structural characteristics of casting solidification and are often used as jade imitations.

Second, water bubbles.

The main mineral components of water foam are albite and quartzite, followed by a small amount of pyroxene and amphibole minerals. Its chromogenic substances are actinolite and epidote arranged in a certain direction. The "blue flower" in the floating blue flower is amphibole mineral, which is not emerald when observed with a magnifying glass and contains more stone flowers or white cotton. This is a very important feature, and the overall color is gray or white.

In the jewelry markets of Kunming, Ruili, Tengchong and some big cities in the mainland, there has been an "ice seed" jade with good water head and transparent or translucent appearance.

The overall color is white or off-white, with few white spots and uneven distribution, and the color tone is blue and dark. This kind of jade is called "stone", and the blue tone is called "blue flowers floating underwater".

Its appearance is very similar to the ice jadeite with good water head, especially the floating orchid variety, which is similar to the egg white land of floating blue flowers, even the ice jadeite and glass jadeite, so it is often used by unscrupulous businessmen to pretend to be high-quality jadeite and sell it at a high price in the market.

Third, foam stains.

Produced in Myanmar, it is a common gray-green stone with different water heads in Yunnan border. People call it foam stains. Because of its dark color, it is made into thin-slice ornaments. The main mineral composition of foam spots is sodium chrome pyroxene, followed by jadeite, omphacite, chrome chrome jadeite and glaucophane. In fact, it is sodium chrome pyroxene. Among them, the one with certain transparency and jade feeling is called chrome pyroxene jade. The hardness is 5~6.5, the specific gravity is 3. 14~3. 17, and the refractive index is 1.63~ 1.66.

Fourth, the tumbler jade is produced in the grape region of northern Myanmar and is named after the place name. Green is banded and variegated, with good transparency in general and poor transparency in a few cases. The main mineral is hydrogrossular, followed by zoisite, Fushan stone and hornblende.

It turns deep purple under the color filter, which is actually garnet. The hardness is 6.5~7, the specific gravity is 3.4 1~3.44 and the refractive index is 1.7 1~ 1.72.

Grape producing areas also produce a kind of stone that is purple under the color filter. This kind of jade has good transparency and is blue-blue-green-blue. The main minerals are opal, timely and chalcedony. In fact, it should be called protein timely jade. The hardness is 5.5, the specific gravity is 2 13, and the refractive index is 1.45, which should be strictly distinguished from hydrogrossular.

Five, sleepy

Trapped in the border area between China and Myanmar, it is transparent to translucent, gray-blue or blue-gray, and the color is in the form of a national bundle and a band. The main minerals are tremolite and actinolite, with a small amount of chromite. Hardness 6, specific gravity 2.96~3.02, refractive index 1.60~ 1.6 1. It is really nephrite.

Extended data:

Distinguish jade from others.

First, in the jade market, there are often some precious stones mixed with some exquisite artificial jade. Therefore, I am afraid that we are most concerned about the identification method of jade, which plays an important role in ensuring that we will not be cheated by jade merchants in the future. The more reliable identification methods are: seeing, listening and testing.

Look, mainly depends on the crystal transparency, real jade has strong transparency and oily luster; Listen, Zhen Yu's voice is crisp, but her voice is dull; In the test, the real jade scratched the glass, but the jade itself was intact.

Second, the identification of jade is mainly to prevent nitrate from being regarded as white jade. It can be identified from the aspects of color, jade, fracture, impurity, specific gravity and sound.

1) color

The white of white jade is often slightly blue, and there are few people who are extremely white and pure white, while nitrate is evenly white and pure white. After the light is on, nitrate still has a slight orange light.

2) Properties of jade

One of the properties of jade is moist and greasy, like cream, while nitrate has a bright and moist feeling, but it has a naked feeling, but it has the feeling that thief light flashes in the bright and moist.

3) Fracture

This is an obvious difference. The fracture of white jade is stony, dull, serrated or serrated, while the fracture of nitrate is material, bright and shiny, and shell-shaped. Although jewelry appraisal can't be destructive, it can be observed through some accidental bumps, unpolished grinding surfaces and corners.

4) impurities

There will be no bubbles in jadeite, but there will be bubbles in nitrate. Sometimes it is difficult to be observed because of its translucent color, and sometimes it is rare because of its good quality. But as an appraisal, you can't stop without finding evidence.

Sometimes we can check from the surface. If there is trachoma, that is, there are bubbles on the surface, it can also be proved to be nitrate, because white jade does not have this characteristic, and the bubbles inside can also be checked under strong light.

5) Specific gravity

The specific gravity of jadeite is between 2.9 and 3.1,and the nitrate is about 2.5, which is lighter than nitrate.

5) Sound

The voice of jade is dignified, and the voice of nitrate is crisp. In some cases, jade and nitrate can be identified by their different sounds.
