How to tell the age of jadeite? A must-learn!

In the industry, jade is often described as old, tender or new . People who don't understand are often confused. What? It turns out that jade can be divided into "old" and "tender" ? Well today I will talk to you about it.

What is a species?

The type refers to the texture of jade, that is, the size of the grains in the internal structure of jade, their arrangement, and the degree of tightness of their integration . Species is also called germplasm, and in mineralogy it is called the structure and texture of a polycrystalline aggregate.

But in reality, the "size" of crystals is described by "coarse" or "fine" ; the tightness of the binding is described by tight and loose ; and the "luster" is the embodiment of equal and unequal particles, order and disorder.

Since the size of the crystal is positively correlated with the degree of bonding between them, if the grains are coarse, the crystal gaps are sparse and the bonding is loose, which means the mineralization age is relatively recent; if the grains are fine, the crystal gaps are small and the bonding is tight, which means the mineralization age is relatively ancient. Therefore, people extended the concepts of old seeds and new seeds, and used "old, new, and tender" to describe the germplasm.

Old species VS new species VS new and old species

Old type: It is also often said "old type", which means that the grains of jadeite are fine and tightly combined, that is, the type is fine and the texture is good, so old type is good type, and old type means good type.

New seeds: also often said as “tender seeds” or “tender seeds”, it is not customary to say “new seeds”. It means that the grains of jade are coarse and sparsely connected, that is, the quality is coarse, or the texture is poor. New seeds are bad seeds, and tender seeds are bad seeds.

New and old varieties: The germplasm between the old varieties and the new varieties is called new and old varieties in the jargon. This statement is more commonly used in raw materials and less in finished products.

In summary, old jade refers to jade with a long mineralization age, fine crystals and good quality, while "new jade" refers to jade with coarse mineralization crystals and poor quality.

Physical diagram

Tender Bracelet——

▲ Bean-type bracelet, with tender seeds, rough base, obvious granularity, no moist feeling, and not transparent under natural light.

▲ Ice-glutinous bracelet, with tender texture, coarse jade, loose structure, obvious granularity, and more cotton and impurities.

An older bracelet -

▲ The glutinous bracelet is relatively old, the jade is fine and the grains are almost invisible.

▲ Hibiscus bracelet, which is an older species, has fine jade quality, good moisture and a certain degree of transparency.

Tender seed pendant——

▲ The bean-type Pixiu pendant has coarse jade, obvious grains, tender quality and very low value.

▲The glutinous white oil green Ruyi is of tender quality, poor carving and low value.

▲The glutinous rice peace locket is tender and has good color, so it is worth some money.

An older pendant -

▲A good quality glutinous Ruyi, the jade is relatively delicate and moist, but the transparency is poor, so it cannot be considered to be of good quality.

▲ An older type of glutinous orchid, also called glutinous orchid, has a delicate jade texture and no grains can be seen when the light is transmitted.

▲Rare old-style glutinous jade peach, the jade is very delicate and soft

Many people believe that the more transparent the jade is, the older it is. In fact, this is not true. Ice jade can also be divided into old and young types . The key to whether the jade is old or young is whether the jade is delicate and moist enough , which has no necessary connection with its transparency.

Tender ice jadeite——

▲ Tender ice type, the jade is rough, the moist feeling is poor, the granular feeling is obvious, there are many cotton and impurities, although it is relatively transparent, but the value is not high.

▲ The ice-type dragon ball still has some luster, but you can tell it is tender when you look through the light

Old ice jadeite——

▲ The leaves of the ice type are old, with a delicate and moist jade texture, and an icy sheen.

▲The leaves of the ice type are considered to be an old type.

▲ The leaves of high ice-type Qingshui are very old, the jade is delicate and pure, transparent and has a strong luster, excellent gloss and very high quality.
