Type A Jade (Natural Jade):

Type A jade, natural, untreated jade, only undergoes a traditional process, including plum juice washing and polishing with beewax.These procedures are internationally recognized as standard practice and are not defined as "artificial treatments".It is not disguised with any dirt picking, high temperature or high-pressure treatments.The color is natural, so they are called "true color".

Type B Jade:

Type B jade, bleached, polymer impregnated jade. To distinguish Type B jade, you need to know the structure of jade as well as the principle and procedure of the processing of Type B jade. We know that the chemical composition of jade is NaAlSi2O6, which is composite with columnar crystals and the interlocking structure made it to be a very tough mineral stone. Because of oxygenation and hydrolysis, oxides such as iron, manganese and calcium are adhered on the surface and even immerge into the interspaces between crystal, which turn the color of the jade into orange, brown, black, or grew. These impurities influence the transparency, as well as the color of the jade. The purpose of using powerful acid such as sulfuric acid and chemical on the jade is to remove these impurities, improve the transparency and to make the green color of jade uninfluenced by the varied colors (caused by the chrome and iron ion), which make it more delicate and charming (the green color is the original color of the jade which cannot be removed and affected by powerful acid). Sometimes the acid is heated to increase its strength. After the jade has been chemically bleached to remove impurities, it will then impregnated with polymer to enhance translucency. Polymer is injected into the jade with the use of a centrifuge. At this stage the jade is covered with hard and clear plastic like coating.

The quality of this kind of jade is not natural, its structure integrity has been damaged and become loose. The artificially treated Type B jade will become unstable and discolor after a certain period of time since heat or household detergent will break down the polymer.

Type C Jade:

Not only the Type C jade has been chemically bleached to remove impurities, it has been dyed to enhance its color.The color will be very rich but will not retain its brilliant coloration and will discolor after certain period because the chemical used on treatment is not stable.The transparency and equality will be loose under strong light, body heat or household detergent.
