From a scientific point of view, cultivated diamonds are exactly the same as natural diamonds, the only difference being where they are formed.
Cultivated diamond has no difference with natural diamond in color, granularity, clarity and other aspects, but the market price of cultivated diamond with the same granularity and grade is only half or even lower than that of natural diamond. According to statistics, the retail price of cultivated diamond in 2016 is about 80% of that of natural diamond. From 2017 to 2020, this proportion will be reduced to 65%, 50%, 50% and 35%, respectively. Lower production costs and retail prices provide strong support for cultivating diamonds to further expand market share.
In the global diamond consumer market, the United States is the main consumer market, accounting for 80% of the market share, China is the second largest consumer market, accounting for 10% of the market share, other countries accounted for 10% of the market share.
