The species of jadeite, also known as the “head of jadeiteâ€, is a comprehensive summary or division of jadeite, which combines the size of the mineral particles inside the jadeite and the closeness of the bond between the mineral particles. The jadeite species in the jade industry mainly refers to two aspects: one refers to the size of the mineral crystal particles inside the jadeite; the second, according to the density, hardness and the degree of bonding between the crystals of the inner mineral crystals of the jadeite. Today we will talk about the four most common species of jade. Old species The age of old-fashioned mineralization is early, the block is full of shape, the sofa is obvious, the fog layer is even, the bottom is dense, and the color is bright. Commonly there are mountains, water stones, half-mountain and half-water stones, all of which are homogenous and multi-image. The composition of the old species is stable, the structure is tight, the hardness is strong, and the specific gravity is sufficient. Throughout the ages, all high-end jewellery and carvings have been drawn from old stone. However, the old seed stones also have differences. Some old stone only experienced a weathering, no fog layer, and the color is not rich enough. Some old stone samples have coarser particles, and the bottom is not delicate enough, often showing insufficient water. Some of the cotton willows stand out, some have too many cracks and so on. In short, there are defects and deficiencies in one or the other. On the contrary, it does not show the precious and hard to find old stone. New species The new species of jade in Myanmar is a typical primary mineral product. There is no weathering process, so there is no skin and no fog. This is the basic feature of the new species of jade. Compared with the older species, the new species has a low degree of compactness, weak toughness, and is easily broken. The color is light and the color is weak. The composition contains more aluminum, the specific gravity is lighter, and the hardness is slightly softer. However, the new type of block is larger, the bottom chapter does not lose the glass luster, and is still the top grade in jadeite. New species of stone are used for carvings and low-end ornaments. Tender seed It is a special product of the transition from primary to secondary. The block has sand shells, water shells, some fog layers, and some without fog layers. Due to insufficient weathering, the thickness of the skin is not uniform, the sand is disorderly and weak, and the color of the soil is more obvious. The pine flowers on the skin are mostly dull and dry, and the fog layer is thin and easy to stalk. If there is cockroach, the brightness of the cockroach is weak. The biggest regret of tender seed is that the color is extremely unstable. Due to insufficient silicon and oxygen, once cut and polished, the color is easy to fade and the finish is low. If the East Millstone, the green will become lighter, the five points of green will fall below four points, the gloss is only between glass and rouge, although the tender stone is not mature enough, in many mid-range and above, there are still many With tender stone as raw material, once the color is stable, it is still a rare jade. variant The jade variant is a normal phenomenon that occurs in all natural minerals. From the perspective of genesis, many blocks that should form jadeite are the transitional stage in which the rock mass is metamorphosed and confessed. The geological effect has changed, making it impossible to become an authentic jade. Variants of jade have different composition, structure and physicality, and have the characteristics of jade in appearance, which makes it difficult to distinguish and identify. The performance of the variety of jade, the field is unknown, the seeding is difficult to change, the flesh is not divided, the structure is loose, the hardness is low, the specific gravity is light, the water is short and evil, and it is easy to break. Most of the varieties of stone can't be cut and produced, and basically have no value.
