What is Type "B" Jadeite?

Type B jadeite is a type of jadeite that has been treated with chemicals and/or heat to enhance its color and clarity. It is considered to be a lower quality and less valuable form of jadeite compared to Type A jadeite.

The treatment process for Type B jadeite involves soaking the stone in a solution of acid and polymer resin, which fills in any cracks or fissures and enhances its color. The stone is then heated to improve its clarity and remove any remaining impurities. This treatment process can improve the appearance of jadeite and make it more affordable, but it also means that the stone has been artificially altered and is not as valuable as natural Type A jadeite.

Type B jadeite is commonly used in commercial jewelry and carvings because it is more readily available and less expensive than Type A jadeite. However, it is important to note that some unscrupulous dealers may try to pass off Type B jadeite as Type A jadeite, so it is important to purchase from a reputable dealer and to have the stone authenticated by an expert if necessary.
