A goods

The jadeite A goods (called the old jade on the market), in short, are simply natural jade without any chemical treatment. In addition to the conventional engraving and polishing process, there are no other jade ornaments that are artificially camouflaged. What is the original and what the finished product will remain.

Under the 10 times magnifying glass, the unique characteristics of jade are generally presented, such as the nucleus of the cleavage surface.

Polished with a gentle undulation of orange peel effect, a veined root and glass - waxy gloss.

"Turtle crack" - B goods

Jade B goods (called "new jade" on the market) is a product that is artificially treated with natural jade stone. It is washed with strong acid to remove impurities and glue to increase the strength of jade. Because the resin glue filled in the jade jade gap is low in hardness, it is easy to form concave grooves and cracks during the cutting and polishing, which is called "etching texture". The pickled jade background is very white because the pickling removes the tan and grayish black in the jade.

Jade B goods are harmful to the human body. Because the internal heavy metal content of B goods is seriously exceeded, it will have adverse effects on the human body after long-term wear, and serious endocrine disorders may occur. Women may cause adverse reactions such as menstrual cramps and dizziness.

"Green Tree Roots" - C goods

C goods are artificially dyed jade. Generally, green dyes can only be attached thinly to the grain gap near the jade crack, forming a green color shape distributed in a tree-like shape. It is worth mentioning here that the color formed by the reduction of secondary colors such as maroon, maroon and oil cyan is naturally formed in the interstices of mineral particles.

"Loofah" - B+C goods

B+C goods are jadeite that has been soaked with strong acid and added with a dye and then filled with resin. After pickling, large pores are formed between the particles constituting the mineral, and the dye enters and precipitates on the surface of the particles to form a three-dimensional network structure. It is accompanied by the blurring of the green ribbon and the identification of the B-type emerald acid-etched net.
