This is inferior hetian jade, which can't be called hetian jade. Therefore, merchants and live broadcasters mislead consumers and are suspected of false propaganda and consumer fraud.
Should? Many friends don't know much about jade ornaments like me. I always thought hetian jade was the name of a jade, but it was not, it was the name of a jade.
Hetian jade is a natural tremolite mineral aggregate, which is beautiful, durable, rare and of technological value, and can be processed into ornaments. The secondary minerals may be actinolite, and may contain a small amount of calcite, diopside, graphite, pyrite, chromite, magnetite, yingshi, serpentine, chlorite, epidote, wollastonite, apatite and garnet.
The appraiser also said that if it is Hetian jade, the content of tremolite minerals should reach more than 95%. If it is identified as a carbonate-tremolite jade necklace, it means that the proportion of carbonate is relatively high.
In other words, even if the carbonate-tremolite jade necklace is classified as Hetian jade, it is inferior and should not be sold under the banner of Hetian jade.
In this incident, in addition to the texture of the necklace itself, there is also a certificate that makes consumers suspicious. People like me who know nothing about jewelry and jade can only rely on certificates, but it is very depressing that certificates may not be true from the beginning.
People who bought Hetian jade necklaces in the live broadcast room bought dozens of pieces. As a result, the total weight of jade marked on all appraisal certificates is 40 grams. But I went to find out, in fact, due to the influence of density, texture and porosity, it is difficult for Hetian jade with the same volume to achieve the same weight.
Hetian jade, which is not the same piece, may have subtle differences in mineral composition, resulting in their different densities. Even the same Hetian jade, because the internal structure and texture are affected by temperature, air pressure and mineral state, there will be differences. Moreover, if Hetian jade has pores or cracks, it will also change its compactness and affect its weight.
Therefore, even if the jewelry made of Hetian jade has the same volume and size, it is difficult to ensure that every consumer receives the same product weight. There is also the Hetian jade necklace that this consumer bought in the live broadcast room. All the appraisal certificates are written by 40g, which is not true.
There should be some friends who are as confused as me. If you really want to buy Hetian jade online, you can't buy it once. In fact, ordinary consumers like us who don't understand this can also judge the quality of Hetian jade through some conditions:
Look at the color. Hetian jade is very rich in color. White, cyan, yellow, ink, etc. When judging the quality, focus on the hue, color saturation and lightness of Hetian jade.
Tone the type of specific color, preferably without noise; What is color saturation? Brightness of color; The degree of light and shade is whether the specific color is bright, and it is not good to be too bright or too dark. For example, top-grade topaz should be yellow like a ripe chestnut, good jasper should be green and transparent, and the best jet should be black like pure paint.
See the clarity. To put it bluntly, it refers to the number of defects, specifically cotton pulp, waterline, cracks, impurities, inclusions and so on contained in jade. Most of the dots in Hetian jade are all kinds of mineral impurities. Generally speaking, jade with fewer flaws is better.
Look at the texture of jade. Mainly the degree of exquisiteness and luster. Good hetian jade is mostly made of very fine fibrous tremolite single crystals, which are felt-like. This structure makes it dense, delicate and moist, and has a strong sense of grease.
People like me who don't know anything about jade jewelry generally don't buy it, but if a friend really likes it, I suggest buying it in a physical store. Although the online or live broadcast room is cheap, it is easy to step on the pit.
