Moissanite vs Diamond: Pros and Cons

What is Moissanite?

Moissanite has surged in popularity in the last decade as people look for alternatives to natural diamonds, both due to economic and environmental pressures. Though moissanite can occur in nature, it is extremely rare. Instead, modern science created avenues for these to be replicated in controlled lab environments, resulting in a mining-free stone which couples can feel good about wearing.

Is Moissanite A Good Choice For Engagement Rings?

For engagement rings, the biggest considerations should be beauty, durability and price. Like mined diamonds and lab-grown diamonds, moissanite can be used in any setting, and set in any metal. Moissanite is only second to diamonds in terms of durability. The “Mohs scale” measures the “hardness” of a gemstone. On this scale, a moissanite measures 9.25-9.5 whereas a diamond measures at 10.

Our Moissanite stones compliments any ring setting and metal colour.
Our Moissanite stones boast a higher refractive index, and sparkles brighter than your average diamond.

Moissanite also [controversially] sparkles even more than diamonds. At Cullen Jewellery, our Radiant Beauty moissanite stones have a clarity grading of VVSI-2 [very very slightly included]. Where moissanite differs from diamonds is its “refractive index” which refers to how light interacts with the stone, and what kind of effect it has on the appearance. Moissanite has a higher refractive index than diamonds, meaning when light enters the stone, it bends more, and so it sparkles more brightly than a diamond.

Why You Shouldn’t Get a Moissanite Ring

There is no big secret which should deter anyone from choosing a moissanite ring, only if your heart is perhaps set on a natural diamond, or a lab-grown diamond. The average person can’t tell whether your ring is a moissanite or natural diamond, so instead this decision is one you must make for yourself.

One thing to be aware of is that generally, moissanite are chosen by those wanting a high carat weight, and so the setting and band are usually simple, allowing for the stone to be the star of the show

Most people cannot distinguish the difference between Moissanite and Diamonds. So you can still choose an elegant gemstone at an affordable price.

How Does a Moissanite Compare to a Diamond and Lab Grown Diamond?

Mined diamonds have somewhat of a murky reputation, especially with savvy Gen Z and millennials who are sceptical about greenwashing. The fact remains that though energy is consumed in the process of making moissanite in a lab, it still doesn’t compare to the energy and labour needed to mine natural diamonds, nor the condition it leaves the land and surrounding community in once mining has been completed.

On a physical level, diamonds are graded according to their clarity, colour, cut and carat weight. In regards to the clarity and colour, these don’t vary significantly with moissanite as the stone is produced in a controlled setting, and so it takes some of the investigative work out of the shopping process. Moissanite is also a great way that couples are getting a bang for their buck when it comes to engagement rings, and is becoming a popular option for brides who like the look of a big rock, but not necessarily the price.

Our Moissanite Rings are produced using efficient processes that don’t impact the land, such as mined diamonds.

Moissanite vs Lab Diamond

To the naked eye, you may think there won’t be many differences between moissanite and lab-grown diamonds. Both are grown in controlled settings, but make no mistake – the quality still varies. Like mined diamonds, moissanite has a higher refractive index than lab-grown diamonds. So their sparkle looks colourful, compared to a bluey-grey sparkle of a lab-grown diamond.

If you’re looking for a classic stone, a moissanite is a great option, but what it doesn’t offer is a pop of colour. Lab-grown diamonds come in just about every colour, so you can emulate the look of your favourite celebrity ring for less, like JLo’s pink diamond engagement ring. Yes, you could choose another gemstone like sapphire to create the same look, but this is unlikely to be as durable as a lab-grown diamond.

Each type of stone is available at Cullen Jewellery for a reason. The fiery sparkle of moissanite can’t be replicated by a lab-grown diamond. Nor can the durability of lab-grown diamonds be matched by moissanite. If you’d like to discuss both options with our experts, book a free consultation here.
