The grade evaluation of “Jinjiang Jinsiyu†is based on the fineness, density, blockiness, purity, oiliness, transparency, color, shape and other natural conditions of jade.
(1) Fineness, density, oiliness, and blockiness are essential basic indicators. Only when it is fine enough, the density is large enough, the oil is lustrous, can it have the characteristics of "jade". Only when the block is large enough, can it be used as a condition for playing, polishing, engraving and collecting as a "jade";
(2) Purity, color, transparency, shape, etc., are the grade indicators of “Jadeâ€. The purer, the more colorful or the rare or multi-color combination, the higher the transparency and the more perfect the shape, the higher the value of the goods. In general, the red is less, the white is second, the yellow is more, and the other colors are even less. Based on this, the less rare, the more delicate, the oily and pure, the brighter the shape, the better the head, the more dense the hand, the more precious it is.
