Detailed explanation of the jadeite glass and ice species seem to have a treasure from the inside out, often called Qi Ying. Take a fine colorless glass ring face, shake with your hand to see the fluorescent movement phenomenon. If it is the old pit green glass species, the fluorescent light will cause a green flowing feeling. Different people have different interpretations of what is called Yingying. I personally think that it is not easy to start the fluorescing, and the brightness of the water head is two different things.
The glass material is like white wine. There are hundreds of Maotai and a few dollars of Erguotou. For ordinary people who have not drunk, can you know why? Now, in the jade pendant market, everyone likes to plant, but it is not What kind of glass is sold at the price of Maotai. Generally, the price of glass wool is about 10,000 to 50,000. There is definitely a price difference when you can't afford fluorescence.
Fluorescence is the absorption of ultraviolet light by a substance into an unstable higher energy level. The higher energy level returns to a lower energy level, releasing a specific wavelength of fluorescence.
Qi Ying means that light enters and reflects back and forth between the crystal lattices, so that the light is strengthened, and it feels like the flowing light is inside the jade. Ying Ying depends on the following aspects:
1, the crystal gap should be small - the species should be old.
2. Arrangement of crystals. Is the alignment of the direction is more consistent or the arrangement of the direction is more complicated.
3, the polishing is good or bad, the polished shin is more obvious.
The so-called old species mainly refers to the fine texture, even and round, relatively transparent jade. The so-called ash is actually relatively transparent, and the light does not reflect up and feels dark. The old-fashioned jade crystals are relatively dense, so the "steel-filled" knocking sound is also relatively crisp.
The Burmese jadeite fluorescence is the reflection of the jadeite when it is relatively transparent, which is the same as the convexity of the convex lens. It is not true fluorescence. Therefore, the "fluorescence" of the jade appears in the more full curved part.
