Comparing Quorri DymondIX® to Moissanite
The first difference you notice when comparing a Quorri DymondIX® to Moissanite is the colour. Moissanite stones suffer from a tendency towards muddiness; their hue is usually a faint yellow or grayish 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 colour range, which is the equivalent of a low-grade, inferior diamond. The brilliant white Quorri DymondIX, on the other hand, rates in the upper colorless range of E, which is comparable to very expensive mined diamonds.
A gem’s hardness is measured according to the Mohs scale, where it will achieve a rating somewhere between 1 (the softest) and 10 (the hardest). As expected, diamonds are a 10 on this scale. Moissanite, in comparison, has a hardness rating of 9.25 Mohs. Quorri DymondIX, however, rates at an impressive 9.1 overall.
Brilliance – or sparkle – is compared using a Refractive Index, which measures how much slower the speed of light becomes when it passes through the gemstone. The higher a stone’s Refractive Index, the more light it reflects from its surface. A diamond is singly refractive, with a rating of 2.42.
Moissanite, as presently synthesized, has a rating of 2.65 – 2.70. However, it’s what is referred to as “doubly refractive.” In other words, its brilliance is fuzzier and less focused. This effect is perceived as a doubling of the stone's back facets, which appear blurry to the naked eye.
A Quorri DymondIX®, like a diamond, is singly refractive, with an even higher rating of 2.46. Its facet lines always appear clean and sharp when you look through the top of the stone at various angles.
What we perceive as a glittering rainbow of colour emitting from a stone is called dispersion. This is what gives a gem its fire and brilliance.
When compared to a diamond, Moissanite has a dispersive power nearly 2.5 times greater (0.104 vs. 0.044). However, Moissanite handles light differently than a diamond, and produces birefringence, or double reflections. This causes the fire of Moissanite to seem excessive and fake – the disco ball effect.
The Quorri DymondIX®’s dispersive power is almost identical to a diamond’s – 0.046 – which gives it the same intense fire and brilliance.
Because Moissanite has different optical properties than a diamond, it cannot be cut to the same standards. A Quorri DymondIX on the other hand, is cut to exact diamond proportions, allowing it to display the same intense fire and incredible brilliance as an expensive mined stone.
Despite its drawbacks, created Moissanite has been heavily marketed as exclusive to Charles and Colvard, which means it commands a premium price. In contrast, Quorri DymondIX has diamond-like quality with a beauty that’s virtually indistinguishable from the real thing – yet it remains reasonably priced. It’s truly a brilliant alternative.
Choose Quorri DymondIX. Pure perfection, only better!
