In terms of price, synthetic diamonds are about 40% cheaper than natural diamonds with the same number of carats and quality grade (including color, clarity and cut integrity). ). At present, the average price of a 1 carat diamond on the market is about 50,000 yuan, so the price of a one-carat synthetic diamond is about 30,000 yuan.

In the laboratory machinery and equipment, an artificial diamond can be shaped in only three or four days, and the new technology "chemical vapor deposition" can also make the artificial diamond reach the color and purity of high-grade natural diamond, and the carat number is also higher. This convenience makes the artificial diamonds produce in large scale, and there are several such artificial diamond factories in Henan, China. Of course, the large-scale production of synthetic diamonds has also led to the downward trend of their prices.

Although the production of synthetic diamonds has brought convenience to some consumers, people can own a jewel comparable to diamonds without spending a lot of money, but this is limited to wearing. If investment and collection are considered, the irreplaceable scarcity of natural diamonds is the core criterion to determine its value. Even though the laboratory has produced diamonds with the best quality and size, their value can't be compared with natural diamonds.
