Enhanced diamonds are also excluded from this definition. Dispersion & fire. Compare the average DI of 20, for natural gems, to the average in the exotic diamond-likes, which is>150! Which diamond simulant shows noticeable doubling and strong fire? Thus, if a diamond simulant's RI and dispersion are too low it will appear comparatively dull or "lifeless"; if the RI and dispersion are too high, the effect will be considered unreal or even tacky. Diamond simulant - A diamond look-alike. Our signature diamond simulants are laboratory grown, have a lifetime guarantee, possess the optical qualities of the finest diamonds, and won't dull or fade overtime. While their material properties depart markedly from those of diamond, simulants have certain desired characteristicssuch as dispersion and hardnesswhich lend themselves to imitation. A diamond simulant may be artificial, natural, or in . In the 6H form, moissanite's refractive index is 0.313.
