Jadeite is a highly sought-after mineral that is often used in jewelry and decorative objects. Some sources estimate that up to 90% of jadeite in the market has undergone some form of jadeite treatments. While untreated jadeite, or Grade A jadeite, is the most valuable and desirable option, it is rare to find untreated jadeite in the market, especially in larger sizes and higher qualities. Thus, many buyers are left to consider if they should purchase Grade B or Grade C jadeite that has undergone a treatment process. To make an informed decision, it is important to educate yourself on the various types of treatments and their associated pros and cons.
Common jadeite treatments
- Impregnation with polymer resin: This treatment is also know as “jade stabilization” or “jade enhancement”. It is often used on low-quality jadeite that has visible cracks or pores. This jadeite treatment involves impregnating jadeite with a polymer resin to fill in cracks and pores, making the stone more transparent and improving its appearance. This treatment can also enhance the color of the jadeite, making it more vibrant.
- Bleaching: This jadeite treatment s used to remove discoloration from jadeite. It involves soaking the stone in an acid solution to remove any brown or yellow hues. This can make the jadeite more desirable for use in jewelry, as it can improve the overall appearance of the stone.
- Dyeing: This treatment involves soaking the jadeite in a solution of dye to enhance its color. This is often done with lower-quality jadeite that would otherwise be unsuitable for use in jewelry. The dye can change the color of the jadeite, making it more vibrant and appealing. However, this treatment is generally considered less desirable than natural coloration, and the value of the stone may be diminished as a result.
- Heat treatment: This treatment involves heating the jadeite to high temperatures to improve its color and clarity. The heat can remove impurities from the stone and enhance its transparency. This jadeite treatment is often used on lower-quality jadeite to improve its appearance, but it can also be applied to high-quality stone to enhance their beauty.
- Wax treatment: This treatment is used to improve the luster of the jadeite. A wax or oil-based substance is applied to the stone, which adds a glossy sheen and enhances its color. Pros & cons of treated jadeite.
