The relationship between transparency and the quality of jade jade

Transparency is the expression of matter through the intensity of light. Gemstones and jade have transparency. The transparency of the industry is very important. It is one of the important indicators for testing the quality of gemstones and jade. The term for transparency of a certain material is called “water head”. "Dizi Ling" or "Pit Ling"; poor transparency is called "no water head", "land question" or "boring pit", the former indicates that the material is good, the latter indicates that the material is finished. For example, the two emerald colors are basically the same, but the transparency is different. The transparency (head) is many times higher than the quality of the secondary transparency (no head).

Gems and jade absorb light, and because of the amount of light absorbed, gems and jade have varying degrees of transparency. Gems and jade can absorb light, which is a non-transparent body; if not all light is absorbed, it will have various transparency.

For the same substance, the thickness is different and the transparency is different. Water is a transparent body, but the bottom of the deep sea is a dark black, because the depth of the sea, the light has been gradually absorbed.

When illuminating with strong light, the transparency increases, and when the light is weak, the transparency is weakened, which is the effect of the light source on the transparency.

Therefore, the transparency of gemstones and jade should have three conditions: one is the light source; the other is the absorption of light by gemstones and jade; the third is the thick thickness of gemstones and jade. In these three conditions, the material absorbs light energy as an invariant source and the thickness is variable. Under the same conditions of light source and thin thickness, it can be said that this jade is larger or smaller than the jade. However, gemstones and jade are completely transparent or completely opaque, and are more transparent and translucent. As far as the transparency of gems and jade is concerned, the strict boundaries are not distinguishable and can only be relatively transparent, translucent or opaque.

Transparency has a good effect on the texture and color of gemstones and jade. The transparency is good, and the quality and color of the material can be more beautiful, and the brilliance of fineness and color is weakened. Because transparency is so important, most gemstones and jade are tested for transparency. The transparency of each type of gemstone and jade is within a certain range. It is impossible to go beyond the scope. In this range, there is an optimal standard of transparency. If the transparency is not too transparent, it is not necessarily good. Not the more transparent the better.

In addition, the depth of the color has a great influence on the transparency, the color is deep, the transparency is weakened, and the light transparency is increased.

Both crystal and smoky crystals are transparent and can be mirrored, and the transparency of the crystal is much better.

Look at the transparency of gems and jade, use the sun as the light source, or use a constant light source. In the wild, it is often to knock a piece of material (jade) and use the eyes to experience

To determine the level of transparency, to provide the basis for the selection of the stone.

Observe the transparency of gems and jade, and polish gems and jade, because it can be accurately identified only in the case of light.

The transparency of gems and jade is generally divided into four levels:

Transparent body: Under normal thickness (in terms of products), it can completely see other objects, such as crystal, amber, diamond, zircon and so on.

Translucent body: Under normal thickness, only the outlines of other objects, such as agate and hibiscus, can be blurred.

Micro-transparent: It can transmit light at normal thickness. But I can't live through the image, such as jade, jade, Henan jade, jade jade and so on.

Non-transparent body: In the case of a comparison, there is a strong light source, which can only transmit some light or no light at all, and can not see objects such as malachite, lapis lazuli, turquoise, coral, etc.

The use of transparent gemstones and jade can reflect the inner color, which has great significance for the use, identification and value of gemstones and jade.

Gems and jade have transparency, and you can use the color inside to increase the translucent beauty of the product. The degree of transparency has different reflections on the hue, chromaticity and color form of the inner color. In the use, the advantages of hue, chromaticity and color form can be exerted, and the range of good color is expanded. When identifying and estimating value, transparency is also applied to check for changes in color and texture to distinguish between true and false and estimated value.
