What is the type of jade?

The kind refers to the texture of the jade material. Jade with fine texture is called old or old; jade with coarse and loose crystals is called tender. Because jade is a combination of polycrystals, it is vividly divided into glass, ice, egg white, glutinous, bean, etc. Glass type is the best, bean type and below are very poor and not desirable, fine glutinous type and above are good. Most of the materials used to make B-grade goods are coarse bean or lower grade.

Glass type: It looks like glass, is as transparent as glass, and has a fine structure and uniform particle size, giving people a feeling of ice-clear, exquisite, and dripping emerald water. It is characterized by fluorescence that can be seen with the naked eye and a crisp sound when knocked. Glass jade is the best type of jade, but its quantity is small, so it is extremely precious.

Ice type: The internal interwoven fiber structure is visible, the microcrystalline part is indistinguishable to the naked eye, and the cotton and structure are clearly distinct. It has excellent water head, good outer luster, similar texture to glass, slightly lower transparency, and often contains "white cotton" in the form of dots or small pieces.

Glutinous type: The internal structure is hazy and indistinguishable, and the cottoniness is inside the structure. The glutinous type with good water head can reach the level of ice type. In order to distinguish it from ordinary glutinous type, this is also called ice type bottom.

Egg white type: transparent like egg white, with a little turbidity. Glutinous type is more transparent, with uniform particles and sub-glass luster.

Glutinous type: The quality of the jade is like translucent glutinous rice soup, so it is called "glutinous".

Oil green type: refers to a darker green color. The color is not pure green, but mixed with gray or some blue. Therefore, it is not bright enough and appears dull and dull. Its color can range from light to dark. Because its surface gloss is like oily gloss, it is called oil green (oil immersed).

Bean type: The crystals are coarse and easy to see with the naked eye. The boundaries of the crystals can be clearly seen, and they look very much like mung beans. Due to the coarse grains, the transparency is often poor.

Golden thread type: refers to the color of jadeite distributed in thread-like shapes and arranged parallel to each other. We can clearly see that the green appears intermittently along a certain direction. Of course, the green stripes can be thick or thin.

Huaqing Type: The base color of jadeite is green or colorless, the green can be light green or dark green, and the shapes can be silky, veiny, lumpy or irregular. Although it is green, its distribution is extremely irregular, which is also the biggest feature of the Huaqing jadeite. The Huaqing jadeite is opaque to slightly transparent, with rough crystal grains. The shape of the columnar and granular mineral crystals can be easily identified with the naked eye. It lacks wateriness and its transparency is often poor due to its rough structure.

Tielongsheng: Tielongsheng is the transliteration of Burmese, meaning full green. It is a kind of jadeite (controversial). It is produced in the Longken mining area of ​​Myanmar and is also known as "Tianlongsheng". The texture is relatively uniform and fine, with relative water head (higher gloss). The main mineral components are jadeite and chromium-containing jadeite, which account for more than 90%, and high-quality iron ore accounts for more than 95%. Secondary minerals include a small amount of chrome amphibole, chromite, kaolinite, etc. The structures of Tielongsheng jade are mainly granular metamorphic structure, porphyritic granular metamorphic structure, columnar metamorphic structure, etc.
