The first difference you notice when comparing an Aterna® to Moissanite is the color. Moissanite stones suffer from a tendency towards muddiness; their hue is usually a faint yellow or greenish tone that becomes even more prominent as the stone increases in size.
Unfortunately for Moissanite, diamonds are valued by how closely they approach colorlessness. Most Moissanite stones would grade within the I-K color range, which is the equivalent of a very low-grade, inferior diamond. Newer versions of Moissanite have been introduced, but they still only range in the G/H color. The Super brilliant Aterna, on the other hand, rates in the upper colorless range of D-F, which is comparable to very expensive mined diamonds. Simply take a look at the two rings below - one created with Moissanite and the other with Aterna lab gems. The difference is very noticeable and the choice is obvious!
Because Moissanite is faceted to maximize the high refraction of Silicon Carbide it has different optical properties than a diamond. It cannot be cut to the same diamond standards and produces a lower carat weight for the same size stone. Aterna, on the other hand, is cut to exact diamond proportions -- Every Aterna is Ideal / Excellent cut allowing it to display the true essence of a diamond.
