>There are three categories of jade, type A jade which is of superior quality and type B and C grades. Type A grade jades are more in demand and the prices for them are higher too. To fulfill the customers demands the manufacturers use chemical bleach to remove the impurities from lower jades thus damaging the structure in the process. This jade then gets classified as B grade and C grade jades.
• Types A Jade – this is a natural, untreated jade which undergoes natural processes of plum juice washing and polishing with beewax. This procedure does not classify under artificially processed method as they is no high temperature or high pressure treatment used.
• Type B Jade – this is an artificially treated jade which is oxygenated and hydrolyzed with oxides like magnesium, iron and calcium which tend to change the color of the jade into brown, black, orange or grey. Strong acids are used for its treatment to remove the impurities and the original color of jade is not affected by powerful acid treatment. However this jade can discolor or become unstable as time passes.
• Type C Jade – this jade has been chemically treated to remove impurities and been dyed as well to improve the color. The color will look impressive but will not retain the quality with passage of time.
