What is the best man-made diamond or diamond simulant?

Synthetic Moissanite: This is the hardest one to differentiate, and the most convincing one, with a brilliant and fire close to diamond, and a hardness of 9.15 it is the hardest diamond simulant so far. read more

Man-made or diamond simulants are essentially the same and are an object or material with gemological characteristics similar to those of a diamond. The most common diamond simulants are high-leaded glass (i.e., rhinestones) and cubic zirconia (CZ), both artificial materials. read more

Lab diamonds are man-made diamonds that consist of actual carbon atoms arranged in the characteristic diamond crystal structure. Simulants do not have the same chemical and physical properties as diamonds, and merely imitate the appearance of a diamond. Therefore, simulants sell at much lower prices than cultured diamonds. read more

There are two main types of diamonds which are man made - synthetic diamonds and diamond simulants: Simulant Diamonds look similar to real diamonds, but they are physically different from diamonds. Simulant diamonds have been available since the 1970's in the form of cubic zirconia, and in the past decade in the form of moissanite and carbon coated cubic zirconia sold by companies like Asha and Miadonna. read more
