Are there so many different kinds of luster in jade? Learned something new again!

Jewelry, jewelry, brilliance. It can be seen that for jewelry, luster is a must and very important. The same is true for jadeite. Its physical properties are defined as glass luster , while in daily life it is often referred to as fluorescence, hard light , etc. So how many types of jadeite luster are there and how can we distinguish them?

Jade is a jade stone with a polycrystalline interwoven structure . Simply put, it is a collection of countless translucent mirrors with their own reflective properties. The "mirrors" of jade not only reflect each other, but also shoot at each other. These optical reactions constitute what we often call the gloss of jade.

Generally speaking, for a jade product with a thickness of about one centimeter and a round shape, when it shows visual effects of fluorescent light, oily light, rigid light, glass light, waxy light, and stone light, the quality, water quality, and transparency of the jade crystal can be divided from the side accordingly.

There is no strict distinction in the luster of jade. In addition to the glass luster defined by physical properties, in the jargon , fluorescent luster, hard luster, and oily luster are usually the best, followed by waxy luster, and the worst is stone luster.

1. Fluorescence

The luster of jade is actually a normal optical phenomenon.

When the micro-crystals inside jade are arranged neatly and orderly, when the light enters the jade, the overall refractive index becomes more obvious, which is often called luster.

Jade with a fluorescent feeling can give people the feeling that the jade is brighter than its surroundings at any angle.

The fluorescence of jadeite is related to its quality and water content. Jadeite with good quality, sufficient water content and high transparency will have obvious fluorescence. On the contrary, it will need to be seen under strong light.

Theoretically speaking, all jadeite of the glutinous grade and above can exhibit the fluorescence phenomenon, and the closer the shape of the jadeite is to a perfect circle, the more obvious the fluorescence effect will be . This is also one of the reasons why most jade products are round or have rounded lines.

2. Oily light

Oily luster can also be understood as a sticky feeling, which means that visually, the jade appears to be very smooth, which requires the jade crystals to be quite delicate.

When light enters jade, the same beam of light is decomposed into many rays of uniform size that gradually diffuse. They are evenly distributed on the surface of jade crystals, ensuring the transparency of the jade while also reflecting the shape of the light when it shines on a single crystal.

3. Rigid light

Rigid light represents the excellent transparency and reflective ability of jade crystals, which is often referred to in the market as "full of rigidity, having a strong rigidity, and having rigidity" and so on.

Jade crystals are translucent. Relatively speaking, the intensity of reflected light determines the transparency quality of jade from the side. Jadeite with strong rigid light can also produce a similar glowing effect under natural light.

4. Glass luster

Glass luster is a light characteristic possessed by most natural jadeite. The surface is as bright as glass and the transparency ranges from transparent to translucent.

5. Waxy light and stone light

As for the waxy luster and stone-like luster, they generally appear on inferior or acid-washed B-grade jadeite.

The main problem with jadeite of poor texture is that the crystals are loose, the quality is tender, and the light transmission effect is poor. No matter how good the water head of the jadeite is, it will have a loose visual effect. This is waxy light.

Stone luster, as the name suggests, means that jade is like stone and its luster is not strong. Jadeite with this kind of glossiness, after polishing, has very poor transparency and lacks spirituality, looking like a piece of stone, which is the so-called heavy stone nature .

After reading this, everyone should have a better understanding of the luster of jadeite. Only by mastering the secret of jadeite's "light" can you buy the jadeite you like more accurately~
