…These treatments are considered fraudulent unless disclosed. Another coating treatment applies a thin film of synthetic diamond to the surface of a diamond simulant. This gives the simulated diamond certain characteristics of real diamond, including higher resistance to wear and scratching, higher thermal conductivity…
Its low cost and close visual likeness to diamond have made cubic zirconia the most gemologically and economically important diamond simulant since 1976.
