Only rare large carat diamonds are eligible to be among the auction houses, so that rich ladies can bid at high prices. Ordinary pawn shops and jewelry stores in the market prefer to recycle 999 gold rather than diamonds under one carat. China's second-hand jewelry market lacks strict supervision. Are there new and old standards for diamond jewelry recycling? Can the seller provide the original invoice and appraisal certificate? What criteria are used to define the price of second-hand diamonds? At present, salted fish is the largest second-hand trading platform in China. The news that selling idle jewelry is a routine is not uncommon. Is to keep stepping on thunder and not make money. Many people don't want to sell at all, and few people are willing to pay for it.

Therefore, it can be seen that although diamonds are expensive, their cost performance is really low. As a commodity, Mosang stone's jewelry characteristics and cost performance are the most real factors. The hardness of mulberry stone is 9.25, which is only lower than that of diamond. The dispersion value is 0. 104 and the refractive index is 2.648-2.69 1, both of which are higher than that of diamond. Therefore, mosan stones with better colors seen in the market are mostly optimized and can be said to be excellent substitutes for diamonds.

The poor quality of Mosan stone is also a wrong idea. As mentioned above, the hardness of mosan stone is second only to that of diamond, and the cleanliness of high-quality mosan stone is also excellent, usually reaching VS2 to VVS. Compared with colorless diamonds, the colorless Mosanite of Mo Wei jewelry is also very cost-effective. Mosan stone also has better fire color than diamond. Moss stone is harmless to human health and will not cause cancer. And as jewelry, Mosang stone is very suitable for daily wear.

Two diamonds with the same carat and mosan stone have reached the D-color VVS clarity. Bian Xiao carefully observed the two gems and found that there was no difference in appearance. Experts told me that ordinary people can't tell a diamond from a Mosan diamond with the naked eye. Subsequently, the industry directly distinguishes it in two very simple ways; Using specific gravity liquid, diamonds sink and mosan diamonds float. Another way is to draw a line on white paper and put two gems on the straight line. What you can see through the gem is the Mosan diamond, but what you can't see is the diamond.
