Color is the first factor to evaluate jade. The standard to achieve good color is: strong, positive, positive, and.
Concentration: refers to the depth of the color. In terms of green jade, the concentration is preferably between 70% and 80%, and 90% is already too thick.
Yang: refers to the brightness of the jade color. The brightness of the jade is mainly determined by the proportion of green and black or gray in the jade. The green color ratio will be brighter. If it is black or gray, the color will be gray. Experts often adopt the image method to express the fresh color of the color. For example: boxwood green, parrot green, green onion, green pepper, all refer to the color of fresh yang. Spinach green, oil green, river green, black green, refers to the dull dark green color.
The more fresh the jade, the higher the natural value.
Positive: It refers to the range of hue, depending on the ratio of the primary color to the secondary color, that is, to be pure, not to mix other colors. Otherwise the value will decrease.
And: refers to the uniformity of the color distribution of the jade. The color distribution of jadeite is generally uneven, and it is not easy to get a jadeite with a uniform color distribution.
The best color of jade: it should be pure color, concentration is 70%-80%, Yanyang is bright, color distribution is even, this kind of high-grade jade, the customary habit is called old pit.
