1. Emerald is green, but it is an iron dragon. Tielongsheng, a kind of jadeite in Gan Qing, is a mid-range jadeite with bright green color, poor opacity, loose structure and columnar crystals arranged in a certain direction, which can often be seen in the market.

2. Jade is opaque. It is likely that the internal structure, impurities, color, thickness and other factors of jade will seriously affect the permeability of jade bracelets. Structure refers to the degree of crystallization of minerals that make up rocks, that is, the size, uniformity and shape of jade particles.

3, too thick or quality problems. Some jadeites are too thick, so the lighting is opaque. This kind of jade still depends on the quality to determine the value! The more transparent the underwater light of the same kind, the cleaner the bottom, the more delicate the meat quality, and the higher the value of jadeite without floating cotton.

4. The jadeite itself is poorly planted with water, and the jadeite crystal particles are coarse. After waxing or soaking, the color is improved, making the color darker and brighter. After wearing it for a period of time, the paraffin wax is oxidized and peeled off, and it is reduced to the original seed water of jadeite. The transparency is weakened, and the color transfer and mapping ability is poor, which makes the color fade.

5. No, whether it's nephrite jet or jadeite jet, the flashlight can transmit light. The original stone can also transmit light unless the light is wrong.
