Which one do you like most about jade? What are the factors for evaluating jade? How is the color grade of jadeite divided? With these questions, let's learn how to judge the best jade!
Jade evaluation factor
1, look at the color. See if the color is pure, rich, even, and use a spotlight to check for hidden variegated colors. It is better for the color to be rich, pure, uniform, and the impurities are small. Emerald green has a higher price, followed by red and purple. In the green, it is better to use fresh, slightly yellowish three-water-containing seedling green, followed by gem green, river green, and oil green, all of which are evenly distributed in green.
2. Observe transparency. Observed under strong light, the higher the transparency, the better.
3. Listen to the sound. It is better to have a crisp and sweet sound.
4. Observe the green and stone flowers. For light observation, there are other mineral particles in the jade (ie, green), and often have closed block white flowers and stone flowers. Both are less good. The finer the structural particles, the better, and the best.
5. Look at cracks and dark spots. Some of the cracks are present in the ore, and some are caused by processing, and less is better. Black spots are black spots everywhere in the jade, but also small and small.
6, look at the processing level. "Jade can't be a weapon." Observing the design, carving the shape and polishing, it is better to have a smooth surface, good polishing, positive shape and novel style.
Emerald color grading
1, special grade: bright green (emerald green), apple green, glass ground (translucent, fine texture), even and bright, no impurities, no cracks.
2, commodity grade: green, oil green, micro-transparent, miscellaneous and translucent grandmother green veins and spotted green.
3, ordinary grade: è—• powder ground, bean green, light green, white delicate, micro-transparent, opaque jade, generally only jade jewelry.
It can be seen that there are many factors for evaluating jade, and the color grading is also different. Through the above introduction, everyone has a deeper understanding of jade related knowledge, I hope this information can help you.
