Jadeite occupies a large proportion in China’s jewelry market and is deeply loved by people. In addition to the color, the transparency, 構造, 明確さ, carving, and size of jadeite also have a great influence on its value.

Brightness-the transparency of jadeite is also called “water head”. Most jadeites are translucent or opaque, and a few can be transparent. The size, 形, and arrangement of the mineral crystals that make up jadeite all affect its transparency. The higher the transparency of jadeite, or the more the water head, the higher its value. When evaluating the value of jadeite, the color of middle and low-grade jadeite is the primary factor of its value, because the value of water and colorless is not as good as colored and anhydrous; when the jade has a certain color, transparency is more important than color, high-end Jadeite must have water and color.

The structure of jadeite is also called texture, which refers to the size, shape and combination of its mineral particles. It directly affects the “species”, “水”, luster and hardness of jadeite. Jadeites with fine particles and tightly integrated are warm and delicate, which is a prerequisite for high-grade jadeites; on the contrary, the quality of jadeites with coarse particles and loose structure will be significantly reduced.

The clarity of jadeite refers to the factors that affect the appearance of jadeite, つまり, the number of defects such as dirty color and cracks. The black blemishes in jadeite are mainly minerals such as amphibole, which are mostly black spots, black silks and black bands, and appear in dark jadeite. The white blemishes in jadeite are mainly minerals such as feldspar, which are mostly granular or massive, and are more common in jadeite with coarser texture. The presence of dirty colors and cracks will affect the appearance of jadeite. The fewer these flaws and the higher the clarity of the jadeite, the higher the quality and value of the jadeite.

Jadeite products generally include two categories: plain surface products and carved products. The plain surface is mainly oval, marquise or saddle-shaped, 等. The raw material is required to be free from cracks. The evaluation mainly depends on the proportion, 厚さ, symmetry and polishing. Carved parts are mainly listed, 花, figures and other sculptures. The price depends on whether it is manual carving or machine carving. It depends on the material design, cutting ratio, carving technology, 等. The ingenious ideas and skill of the craftsmen will play an extremely important role. effect.

The value of jadeite products is not strictly limited by size, but if the quality of color, テクスチャ, 透明性, 等. is the same or similar, the larger the volume, the greater the quality, the higher its value.
