The Difference Between Diamond Simulants, Lab Created Diamonds, and Synthetic Diamonds

Are lab diamonds, cubic zirconia, and moissanite the same thing?

Many consumers are confused about the differences between diamond simulants, lab diamonds and synthetic diamonds.

Diamond Simulants

Diamond simulants are fake facsimiles of diamonds. Diamond simulants do not have the same chemical composition, physical properties, or optical behavior of a diamond. Every known diamond simulant is weaker and softer than a diamond.

Ada Diamonds refuses to sell diamond simulants such as cubic zirconias, moissanite, white topaz, and yttrium aluminum garnet (YAG), as diamond simulants are not diamonds.

Lab Created Diamonds

Lab Created Diamonds are a crystal of carbon created above the Earth via High Pressure High Temperature (HPHT) Diamond Growth or Chemical Vapor Deposition (CVD) Diamond Growth.

A lab created diamond is, in fact, a diamond. It has all the exact same chemical, optical, and physical properties of a diamond that was formed under the Earth and extracted by an industrial mining operation.

Synthetic Diamonds

A synthetic diamond is another FTC-approved name for a laboratory-grown diamond. 'Synthetic' is the preferred name used by the mined diamond industry as they believe that the term 'synthetic' cheapens the product and promotes the 'fakeness' of lab-created diamonds.

Furthermore, it creates confusion between lab-grown diamonds (which are diamonds) and diamond simulants (which are not diamonds).
