Is it true that the bigger the jade is, the more valuable it is?

Anyone who has bought jewelry and gold knows that gold and silver are priced by gram; colored gems are priced by carat; for them, size and weight are the main factors that determine value.

What about jade? Is it the same? The pricing of jadeite is very special, and there are many factors that determine the price. The price is not simply determined by size or weight. A small egg-shaped jadeite, because of its excellent quality, water color and texture, is more expensive than an ornament weighing several kilograms, or even several times more expensive.

In addition to the most basic qualities such as quality, water color, etc., the shape, aesthetics, and cultural connotations will also affect the value of a piece of jade.

Are jadeites with certificates necessarily real jade?

Many jade lovers only look at the certificate when buying jade, and think that if it is written on the certificate that it is A-grade jade, then it is natural jade. But what they don’t know is that now the certificate can also be a “processed certificate”. Yes, certificates can be forged. The jade certificate issued by a professional testing agency is the most reliable. If the jade seller is unwilling to even issue a certificate, there must be a problem!

How to identify the certificate?

1. Check the authenticity of the certificate

First of all, we need to distinguish whether the certificate is authentic. Nowadays, the Internet is so developed that anything can be forged. Even jade certificates can be purchased on shopping platforms.

A formal certificate contains basic information such as number, stamp, QR code, telephone number, etc. With this basic information, we can check whether the certificate is genuine.

2. Check the institution of the certificate

Among the domestic jewelry and jade testing institutions, the most authoritative testing institution is

The appraisal certificates are issued by NGTC (National Jewelry and Jade Quality Supervision and Inspection Center) and GIC (Jewelry Testing Center of China University of Geosciences).

In addition to these two, even if it is a test certificate from other institutions, you should pay attention to whether the three logos of CMA, CAL, and CNACL are printed on the inspection certificate, especially the mandatory certification such as CMA.

What do the big five and medium four in the price of jadeite mean?

When talking about the price of jadeite, we often hear words like big three, small four, and medium five. What does this mean?

The price of jadeite can be divided into several levels based on its quality. There are amounts of hundreds, thousands, tens of thousands, hundreds of thousands, and even millions. In order to facilitate the division of price ranges, this special name was used.

The prefix "big, medium, small" indicates the range of numbers. The range of numbers for "big" is: 7, 8, 9; the range of numbers for "medium" is: 4, 5, 6; the range of numbers for "small" is: 1, 2, 3; the number at the suffix indicates the number of digits.

“Three” means: 100 yuan level;

"Four" means: 1,000 yuan level;

"Five" means: 10,000 yuan level;

For example, "Xiao Si" is within 1000~3000;
