The most comprehensive jade knowledge popularization in history, you will understand it in seconds after reading it

Today, I will take you to learn about the knowledge of jadeite.

Too many words to say, too many points to make

Let’s get straight to the point!

Strictly speaking

Jade is a kind of jadeite

A mineral aggregate composed of various fine minerals

That is to say, compared with other jades, it is not only the hardest

Reach 6.5~7; and the ingredients are complex and the effects are more

Different from other jades

01. Jadeite vs. Hetian Jade

Hetian jade has a unique felt-like structure and no "emerald nature"

Jade has "emerald nature"

Hetian Jade

02. Jadeite vs. Serpentine Jade

Serpentine Jade has no star-like flashes

The hardness, density and refractive index of jadeite are higher than those of serpentine jade.

And it has "emerald nature"

Serpentine Jade

03. Jade vs. Hydrogrossular

Hydrogrossular is also known as "South African Jade", "Qinghai Jade", "Doll", etc.

It is red under the color filter, obviously different from jadeite.

04. Jadeite vs. Dushan Jade

Dushan jade turns red under a color filter, but jadeite does not.

Dushan Jade

05. Jade vs. Fushan Stone

Fushan Stone is also known as "California Jade"

Its refractive index is much higher than that of jadeite, making it appear brighter

Fushan Stone

06. Jade vs. Glass

Impersonating jadeite with devitrified glass

It is called "quasi-jade" or "Imoli gemstone" abroad.

The refractive index, density and hardness are lower than jadeite.

Devitrified glass

2. How to judge whether it is jadeite?

Observe with naked eyes or a magnifying glass

If a piece of material consists of minerals

They are columnar or slightly elongated columnar

Nearly directional or interwoven arrangement indicates jadeite

This structure of jade is called "interwoven structure"

●Key Points● Interwoven Structure●

There are three types of interlaced structures:

01

It is a "fiber interwoven structure"

This is the most common structure in jadeite.

It can make jade have high hardness, toughness and transparency.

Most high-end jadeite comes from this

02

It is a "granular fiber interwoven structure"

This kind of jadeite has coarse grains and straight boundaries.

03

It is "other structures", except for 1 and 2

Jade may also have porphyritic metamorphic structure and plastic deformation structure

Fracture structure, replacement structure, etc.

Regardless of the structure

The finer the mineral particles of jade, the tighter the bond between the particles.

The better the texture of jade, the better the quality, and vice versa

3. Are all jadeites green?

In addition to green, jadeite also has white and colorless colors.

Different shades of red, yellow, purple, black, grey, etc.

According to different reasons

Some are born, some are made

01. Colorless

Small particles, compact structure, good transparency, like glass jade

02. White

Loose structure and single ingredients

There are gaps between particles and the transparency is poor

03. Purple

There are light purple, pink purple, purple, blue purple

Purple close to blue, etc.

04. Black

Divided into two types

One is black in normal light.

It is dark green under strong light and is a high-grade jadeite.

The other is dark gray to gray-black jadeite.

Looks more friendly

05. Yellow

Secondary color, mostly due to the mixing of limonite

06. Red

Secondary color, mostly caused by mixing with hematite

4. The “type”, “ground” and “water” of jade?

The mineral composition, color, structure, transparency and other aspects of jade

Can be uniformly referred to as "species" by experts

According to the advantages and disadvantages from left to right:

"Old species" is better than "new old species" is better than "new species"

Remove Color

The remaining aspects are collectively referred to as "bottom" by experts.

"Foundation" or "foundation makeup" etc.

From left to right, they are divided into:

Glass ground, ice ground, glutinous ground, lotus root powder ground, bean ground, porcelain ground, etc.

Some newcomers confuse "seed" with "bottom"

It is called "glass type", "ice type", "glutinous type", etc.

The experts did not correct him, and over time, everyone just said it casually.

By the way

Transparency is called "water head" or "water" by experts.

The transparency of jadeite varies from glassy to greasy.

5. How to buy the best quality jadeite?

Grasp these six words and you can buy top-quality jadeite

01. Color

Good jadeite should have a proper color, the more uniform and harmonious the better.

No color, pure color tone

02. Types

A warm and delicate texture is one of the necessary conditions for high-end jadeite

03. Watering

Transparent jade is rare, the more transparent the jade, the better

04. Clean

Good jade should not have impurities or dirty colors.

Cracks and other factors that affect aesthetics

05. Carving

If you don't carve jade, it won't become a useful thing.

A good carver will add points to your jade

06. Weight

The bigger the jade, the higher its value
