Comparison of moissanite and diamond: Key properties

So what is exactly the difference between diamonds and Moissanite? The following summarises this:


Moissanite scores a 9.25 on the Mohs scale of hardness, while diamonds score a 10. The mohs scale measures a gem’s durability. Diamonds, at 10, are very hard and durable. And since moissanite is close behind at 9.25, it makes a great alternative for engagement rings and wedding rings since the gem can handle the wear of everyday use.


Both moissanite and diamonds have colourless gem options (as well as other similar colour grading equivalents). With both diamonds and moissanite, colour is more apparent in larger gems. Therefore the colour for either is important if looking at larger carat sized stones.

Brilliance or 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 $1,250 at Forever Chic Jewellery which offer best value for money prices, while a 1-carat diamond engagement ring can cost around AUD $4,000 at Forever Chic Jewellery which offer prices up to 50% off diamond rings than most other stores . It’s a huge gap.
