The difference between "Malay jade" and jade

In the 1980s, a bright green and uniform jade appeared in the jade market. The beading or ring face was once deceived by many people and thought it was "a rare high-grade jade". What is this kind of jade? This jade is called Malaysian jade (referred to as Ma Yu, also known as "Malay Cui"), this is just a name. Malaysian jade is not produced in Malaysia. It is the name of a fake jadeite that was sold by some Indian and Pakistani businessmen in the early days of the mainland. Ma Yu is actually a kind of very fine-grained quartzite dyed in green, but there are obvious differences compared with jade:

1. Visually, the color of Malaysian jade is too bright and very unnatural.

2. The proportion of Malaysian jade is 2.65, which is much smaller than the proportion of jadeite 3.24~3.43.

3. The average refractive index of Malaysian jade is 1.55, which is lower than that of jadeite.

4. The color does not turn red under the Charles filter, but the presence of the dye can be observed under the ten-fold mirror, that is, the color is very floating and is a staining phenomenon.
