wholesale costume jewelry The quality of jade

Pubblicato il da Kingjy

It is said that gold is priceless and jade is priceless. The quality of jade directly determines its value. COSÌ, how to distinguish the quality of jade?

One is to look at the color. Color is the most important factor in evaluating the quality of jade. The jade whose color is even, positive, dense and positive is the top grade. “Uniform” refers to uniformity; “Yang” refers to bright colors, giving people a cheerful and non-slumping feeling; “Dense” refers to darker colors; “Positive” refers to no other variegated colors mixed together.

The second is to look at the texture. Jade is a polycrystalline mineral formed by silicate under high temperature and high pressure. The size of its constituent crystals will directly affect the smoothness, transparency and color tone after polishing. Perciò, the finer the polycrystalline structure, the better the texture of jade.

The third is transparency. Transparency is a physical phenomenon that complements texture. The finer the texture, the higher the transparency. If the degree of transparency of jade is like glass, the fineness of its inner crystals can make the light transparent without being blocked.

The fourth is to look at acquired processing. When the jade is mined, it is just like the ore. The colored parts of the stone must be carefully cut into different shapes by experienced professional craftsmen, then processed, polished and carved, polished and waxed before being sold on the market. Perciò, the processing of jade also has a decisive influence on its value.

Five look at the crack. Cracks on the jade may be caused during mining or processing. With cracks, no matter how good its color, texture and transparency are, it will affect its value. Sometimes the cracks are not obvious on the surface, but they can be seen by careful observation in the sun. Especially for jade that has been bleached, faded or dyed, cracks are common.

While distinguishing the quality of jade, it is also necessary to prevent artificial jade from being fake. Artificial jade is made by dyeing glass, plastic and other materials. Glass imitation jade mostly contains bubbles, and the color is different from real jade.

Ovviamente, there are many articles on the identification of jade, which can not be learned overnight, but as long as you have mastered the big principles and have some practical experience, you can still judge the authenticity.
