Experts teach you how to choose jade

What aspects should we start with when selecting jadeite and what should we pay attention to? Simply put, it means "color, water quality, and heavy flaws"

"color"

Color is the most important factor affecting jadeite. The value of color includes four aspects: "positive, strong, positive, and uniform".

Positive: refers to the purity of the color, whether the color is pure green, yellowish, blueish, or other tones (the purer the green, the better, and green with a yellow tint is better than green with a bluish tint)

From left to right: True green, green with a hint of yellow, green with a hint of blue

Thick: refers to the depth of the color (usually the thicker the better)

From left to right: thick, medium, light

Yang: refers to whether the color is bright or gray (the brighter the color, the better)

From left to right: light color, dark color

Uniform: refers to whether the color is uniform or uneven (the more uniform the color, the better)

From left to right: very even, fairly even, uneven

Selection of colorless jadeite

The most common jade on the market is nearly colorless jade. There is no difference in purity, concentration, and uniformity in colorless jade, but there is a difference in yang degree, that is, it is brighter or darker (if other qualities are equal, try to choose a brighter colorless jade).

From left to right: very bright, medium brightness, dark gray

The selection of floating flowers and oily green jade can also refer to the selection principles of colorless jade.

"water"

Refers to the transparency of jadeite. The higher the transparency, the better.

From left to right: glass, ice, ice glutinous, glutinous, bean, stone

The "type" in the most commonly used terms such as "glass type", "ice type" and "glutinous type" is not exactly the same concept as the "water" here, but with the help of these customary classifications, the water conditions can be well distinguished.

There are two other common ways to classify "water":

1. Transparent, sub-transparent, semi-transparent, slightly transparent, and opaque are equivalent to glass, ice, glutinous, bean, and stone respectively.

2. Three points of water, two points of water, and one point of water are roughly equivalent to glass, ice, and below ice.

"kind"

Refers to the texture of jadeite, which is the thickness and density of crystals in jadeite (different from the "type" commonly referred to as "glass type", "gold wire type" and "oil green type").

From left to right: very thin, thin, slightly thick, thick

(The first piece of jade has very fine and dense crystals, often called "old jade", the next two pieces of jade have coarse crystals and loose texture, often called "tender jade" or "new jade", and the second piece of jade is in between the two)

"flaw"

The defects of jadeite mainly include cotton, dirt (variegated color), cracks (cracks)

Cotton: There are fine cotton spots and large cotton balls

Mixed colors: including yellow, brown, black spots and blocks

Grain: Generally thin and short

Cracks: Usually straight, deep, and long, and can be felt with fingernails when on the surface

The impact of defects is not only related to the type of defects, but also to the size, number and location of the defects.

Usually, small cotton spots in inconspicuous positions have little impact on the value of jadeite, with an impact of about 5-10%. Obvious and serious cracks have a great impact on the value of jadeite. The price of jadeite may drop to about 1/10 or even lower than that without such defects.

"work"

The craftsmanship of jadeite includes the shape proportion, polishing, design creativity, etc.

Modeling proportion: accurate modeling, appropriate proportions, and smooth lines are good carvings, otherwise it is not

Grinding and polishing: requires flatness, uniformity and brightness

Design creativity: Good creative design makes full use of the characteristics of the material, and the design is exquisite and distinctive

Good craftsmanship: exquisite and detailed carving

Normal craftsmanship: proper proportions and neatness

Poor craftsmanship: inaccurate shape, unfamiliar lines, poor polishing
