Only high-end jadeite has the characteristics of luster, glue and hardness. Does the jadeite in your hand have these characteristics?

I believe that when friends are shopping in the market or in the live broadcast room, they often hear merchants say " This jade is shiny/gluey/hard, and the quality is very high! "

But regarding the question of "how to judge whether jade is shiny/sticky/hard", it is estimated that most jade lovers would not be able to give a clear answer.

So, today, following this article, we will systematically understand the luster, glue and hardness of jadeite!

Although there is only one word difference between "qiying", "qijiao" and "qigang", the concepts are different!

One thing that is certain is that only high-grade jadeite with an old species and fine texture will exhibit the above three optical phenomena!

Qiying

The lustre is caused by the fact that the particles inside the jade are arranged too neatly, which creates an uneven contrast of light and dark when light shines on it.

Many friends tend to confuse "reflection" and "luster".

For example, in the jade leaf in Figure 1, the part circled by the yellow circle is not fluorescent, but just reflective!

The part circled in blue in Figure 2 is the real fluorescence! Has a strong contrast between light and dark!

Glue

The stickiness is caused by the irregular arrangement of particles inside the jade, which creates a glue-like stagnant feeling.

If you rotate the jade under natural light, you will find that its surface has a sticky feeling, as if it is continuous.

The piece of jade above has the typical characteristic of glue peeling. Doesn’t it look like a piece of bouncy jelly?

Qi Gang

The hardness mostly appears on old jadeite with tightly combined particles, presenting a cold, metallic light that is relatively strong.

The luster of the jadeite above is obviously much stronger than that of jadeite with a shiny or sticky texture, and it appears sharp and hard.

Most of the time, jade will only exhibit one of the three optical phenomena.

However, there are very few jadeites that exhibit two optical phenomena at the same time.

For example, the jade leaf in the picture above has both the glossy and sticky properties.

Jadeite that is hard often also has a lustrous look. For example, the jade Buddha in the picture above has both a cool and sharp light and a soft, hazy feeling.

But on the other hand, jadeite that is shiny may not necessarily be hard, which is related to the original growth environment of jadeite.

Seeing this, some friends may want to ask: "Which one is the best, the one with gloss, the one with glue, or the one with steel?"

To be honest, there is no superiority or inferiority among these three optical phenomena!

No matter which phenomenon it is, it is a manifestation of the high quality of jade, and its collection value will definitely not be low.

I wonder if the jade in the hands of jade lovers has the above-mentioned optical phenomena?

Some friends can post photos in the comment section so that everyone can appreciate them together.
