Jade refers to jadeite, which is green and jadeite is reddish yellow. Its hardness should reach 6-7, and the specific gravity should be 3.32---3.45. The refractiveindex is about 1.66-1.7.

Jadeite - glass species

As the name suggests, the glass species is as transparent as glass, the quality is very fine, and the hardness is about 7, which is the highest hardness in jadeite, and it is also the best in jadeite.

Emerald - Ice Species

The hardness of the ice species is also high, second only to the glass species, and it refers to the water of various colors of jadeite. It is whiter than the glass species, and the transparency is worse than that of the glass species.

Jadeite - glutinous rice species

Glutinous rice also belongs to the top grade of jadeite, with a hardness of about 7, second only to ice, the color is like glutinous rice, and the transparency is not as good as ice.

Jadeite - oil green species

Oil green species is a kind of dark green jadeite, the color is grayish and blue, but the seed is good and the quality is fine. The light transmittance also varies greatly depending on the stone, but the color is darker.

Jadeite - white background green species white background green species hardness is lower than the above varieties, the background color is white or gray, but the light transmittance is poor, basically opaque, foundation, but individual also have ice bottom, the structure is generally thicker, and the green is relatively bright. Because the green color is bright, the price is also relatively high.

Jadeite - Fulu longevity species

Fu Lu Shou species is a variety of jadeite, refers to a piece of jadeite stone at the same time green, red, purple (or white) three colors, it symbolizes auspicious wishes, on behalf of Fu Lu Shou, three joys, so called Fu Lu Shou species. Light transmittance also varies greatly depending on the stone, and it can be glass, ice, bean, glutinous rice, foundation, etc., and if it has a color, it is very valuable.

Jadeite - violet and purple sapphire

The color background color of violet jade is purple, including eggplant purple, blue violet, pink purple, etc., and the light transmittance ranges from ice to foundation. Purple sapphire refers to the green color of jadeite with a purple base. Violets are especially loved by Europeans and Americans.

Emerald - bean seed

Jadeite bean is a very common jadeite species, it is characterized by coarse particles, poor light transmittance, low hardness, it has many types, such as bean green seeds, ice bean seeds, oil bean seeds, cat bean seeds, fine bean seeds and so on.

Jadeite - black jade

Black jade is a kind of jadeite, the color is black, in general, the light transmittance is medium, when thick, it is not transparent, but when it is cut into thin slices to make carvings, it is dark green, and it can transmit light when it is thin (1mm); It is relatively uniform and has a good polishing degree. The finished products are loved by people in Taiwan, Hong Kong and Southeast Asia.

Jadeite - jade species (can be called ruby, topaz)

Fei refers to the color in jadeite, which is reddish yellow, brownish-red-yellow, brownish-red-yellow, orange-red-yellow. The structure is divided into coarse, medium, and fine grains. Transparency to opacity also varies greatly.

Jadeite - dry green species

The dry green species is a jadeite with a bright green color but poor light transmittance.

The color is malachite green, often containing black, green and black. Its color is intense but uneven; The structure is coarse, with unequal granular and fibrous structures; Poor light transmittance and opacity. The specific gravity is heavier than other jadeite, but the hardness is lower, below 6; It is brittle, and the refractive index is about 1.75 higher than that of other jadeite.

Because the dry green species is too dry, there is no moisture, and the nature is brittle, the hardness is also low, and there are more small carvings.

Emerald - the birth of the iron dragon

Tielongsheng is a transliteration of Burmese, which means full green. However, the structure is granular and the binding mode is relatively loose; Poor light transmittance; Poor hardness. But physical properties: specific gravity

3.30-3.33, refractive index is about 1.66.
