What’s the difference? Lab Grown Diamond vs Moissanite

If you've just started your journey for the perfect engagement ring and are considering alternatives to traditional diamonds, chances are you've come across two popular choices: lab-grown diamonds and moissanite. 

Both stones offer a great alternative to mined diamonds and we are going to identify the differences to make your ring journey easier. 

What is a Lab-Grown Diamond?

Lab-grown diamonds offer an amazing alternative to traditionally mined diamonds. Mined diamonds are naturally formed in the earth for millions of years however lab-grown diamonds are, just as the name suggests, grown in a lab. Choosing a lab diamond is not only more ethical but also more affordable. Lab-grown diamonds have the same physical, chemical and visual properties as a traditional mined diamond. The only difference between a lab-grown diamond and a mined diamond is the way it is harvested and the cost.  

What is Moissanite?

Moissanite is a gemstone (not a diamond) composed of silicon carbide and is known for its brilliance and durability. It has become a popular alternative to diamonds due to its lower cost, ethical considerations (as it's lab-created), and remarkable sparkle. Moissanite typically exhibits more brilliance than diamonds, making it an attractive option for those seeking a stunning and budget-friendly alternative to traditional and lab-grown diamonds.

How can you tell the difference?


A key difference between Moissanite and Lab-grown diamonds is sparkle. Moissanite sparkles more than a diamond and more colourfully. Lab diamonds, on the other hand, display a high level of brilliance, characterised by white light reflection and sparkle. This brilliance is often compared to the sparkle of traditional mined diamonds, as lab-grown diamonds share the same crystal structure and optical properties. Overall, Moissanite sparkles with colourful flashes, while lab-grown diamonds shine with a brilliant sparkle. Your choice depends on the sparkle you prefer.


Moissanite has a hardness of 9.5 (1-10) on the Mohs scale, meaning it is very resistant to scratching making it a great affordable alternative to a diamond.

Lab-Diamonds have a hardness of 10 on the Mohs scale giving them the highest rating, making them extremely resistant to scratching and perfect for everyday wear.

The verdict:

Choosing between a lab diamond and moissanite stone is completely up to personal preference. If you are after an engagement ring that offers a similar look to a diamond, is more affordable and you don’t mind the very-slight difference in appearance, then moissainite could be an option for you. If you are looking for an engagement ring that replicates a traditional diamond with lower costs and more ethical practice, then a lab-grown diamond would be the stone for you.
