Some people call water foam a killer fake in the jade market, but after all, the two can still be distinguished. Look carefully, it seems that the luster is very weak. When asked, it's blisters, 200 yuan each, which is actually more expensive than the average A-grade jadeite. The colorful foam bracelet also sells thousands of pieces, which is much more expensive than agate water crystal chalcedony.
A few hundred yuan of foam.
Tens of thousands of dollars of glass jade.
What's the difference between the price of foam and jade?
Emerald, as a treasure on the earth-rare, beautiful and durable, has played a very important role in human life. The associated foam was not found a few years ago, and now it has spread all over the country. The history of foam in jadeite market is as long as jadeite. Because of its good head, it is transparent or translucent "ice seed" jade-like, with white or grayish white color, few white spots and leucorrhea, uneven distribution, and often blue and green colors float, which is unknown to ordinary merchants and easy to be "captured" by them. There are many kinds of foam in Tengchong and Ruili markets, and those with blue ribbons are called "blue flowers floating in the water". Percussion sounds crisp and sweet, and looks like jade with good quality. It is often processed into bracelets, placards, carvings, etc. and sold in the market, but the price of foam is far from that of jadeite. The price difference between blister bracelets and ice jade bracelets may be several times or even hundreds of times.
It should be noted that the appearance of water foam and jade is very similar, but the price gap is dozens of times. Don't buy a foam with the money you bought jade.
1. Water foam is not emerald like natural A jade, but has more white cotton.
2. The specific gravity of water foam (2.57 ~ 2.64) is much smaller than that of jadeite, and it has obvious light floating feeling compared with jadeite.
3. The refractive index of water foam (1.52 ~ 1.54) is much smaller than that of jadeite.
4. The gloss of water foam is weak, which is due to the low refractive index.
5. Look at the characteristics of blisters-bubble string. Note that it is generally not the expected large bubbles, but usually a small, parallel string of small bubbles. At first glance, it looks like a grain. Under the magnifying glass, you will find a small bubble string, but the small bubble string may be filled with impurities, forming a floating flower.
6. When you look at the grains through the light, you can see the grains of water foaming through the light. Uniform in size, with a diameter of 1-2mm, and its shape is different from that of jadeite.
