Flamingo, diamond simulant

Fake diamond has a better name : "Diamond Simulant". Flamingo is not the only brand in diamond simulants. Another brand is Carat which has shops in prestigious shopping places like the IFC and the Lane Crawford. With the advance of technologies, I'm sure that these simulants are getting very closely resembled to the naturals. And you can buy a one-carat fake diamond ring for just HK$2-3,000, a fraction of the price of a real one. To many people, it's a reasonable price to pay and I heard these diamond simulants are quite popular among the OLs. Is it really good value for money ? It's all about the psychology of reference pricing. People find these diamond simulants reasonably priced because references are made with the real natural diamond. According to the website of Flamingo, its simulants are made from carbon under extremely high temperatures and pressure, like the formation of natural diamonds. Carbon plus mass production, I guess this business could be profiteering. Price is psychological.
