Note:High carbon diamonds are not simulated diamonds, but gemstones with more fire than diamonds. High-carbon diamonds have a higher refractive index and lustre than South African diamonds, and more than 2.5 times the fire of South African diamonds. The only downside is that high carbon diamonds are not as hard as moissanite or natural diamonds, and they will not pass the diamond test.
