Brilliance / Sparkle:

Moissanite and diamonds are so similar in appearance that most people simply can not tell the difference. Brilliance, a gem’s ability to reflect light, gives it its sparkling appearance. A diamond is best known for its brilliance and sparkle however moissanite in fact actually has more brilliance, fire and lustre than diamonds.

The refractive index of moissanite (which refers to the angle of refraction and brilliance score) is 2.65-2.69 while diamonds score 2.42. Diamond and moissanite however have different faceting patterns which refers to how the stone breaks down light into the spectral colours. In large moissanite gems this difference can sometimes cause a slight rainbow sparkle under some lights.


When it comes to choosing between moissanite and diamonds, it really comes down to price for most people. The cost of a moissanite engagement ring varies depending on size and the quality of the stones, just as the cost of diamond engagement rings vary according to cut, carat, clarity, and shape. Lab-grown diamonds are also less expensive than natural diamonds.

The bottom line is that moissanite engagement rings are significantly less expensive than diamond engagement rings: a 1-carat moissanite engagement ring can cost around AUD $2,250 at Forever Chic Jewellery which offer best value for money prices, while a 1-carat diamond engagement ring can cost around AUD $5,500 at Forever Chic Jewellery which offer prices up to 50% off diamond rings than most other stores . It’s a huge gap.
