Teach you how to distinguish between A, B and C grade jadeite in 5 minutes, super practical tips

First of all, we need to determine what ABCD means. Grade A jade is natural jade with pure color that has not been processed. Grade B jade is artificially dyed, and grade C jade is jade that has been dyed and processed. Grade D jade is jade made of other materials.

Jade is actually a very easy to identify jewelry. Generally, jade’s grade can be easily identified through certificates, but we can also identify it with the naked eye before buying. First of all, we need to know that the color of jade is produced because chemical substances in the stone produce chemical changes, and then the color is produced during the long natural growth. The color in jade will have certain growth traces, just like a dot of ink halo in the water. There is a center point, which we call the color root of jade. After having the color root, the color of jade will be blurred and diffused. For example, A-grade jade will definitely have a color root, and its color is spiritual.

Ultraviolet light identification

Merchants nowadays are more cunning. They do not dye the entire item, but dye it piece by piece. However, this dyeing can be revealed by ultraviolet light, because the chemicals used to dye jade will fluoresce under ultraviolet light. Therefore, by using ultraviolet light, it is possible to determine whether the green color of jade is dyed. This is a very convenient way of identification.

Internal Texture

The second thing to look at is its internal texture. This ring is dyed in a different way. By adjusting its inside and dyeing it with acid, if you observe carefully with the naked eye, you can see the spider texture inside.

This spider pattern is caused by cracks created when dye is injected into the jade, which is why this spider pattern appears.
