Gemstones have been cherished and recognized as symbols of love, luxury, and undying elegance. It is no question that diamonds, out of all gemstones, are the most sought-after type of gem. However, a dazzling competitor has emerged in recent years: moissanite.

You may be thinking to yourself “No way. Diamonds are so much better than moissanite!” But we have some secrets to unlock on both stones, so keep reading about diamond vs moissanite and what makes moissanite up for the battle. 

Are Moissanite Diamonds?

 Moissanite, a diamond simulant, is made of silicon carbide and is one of the hardest stones naturally grown on Earth. 

 Moissanite diamonds were discovered in the 19th century, and moissanite is a lab-grown gemstone with excellent qualities that are similar to diamonds and in some ways even better than diamonds.

Diamond is made from one element which is carbon, unlike moissanite which is made from silicon carbide (a mixture of silicon and carbon). 

This distinction in the elements of diamond vs moissanite makes the whole difference between them on all levels: social perception, price and value, and appearance. 


Durability refers to toughness and hardness which reflects the stone’s ability to resist wear, high temperatures, and chemical substances. 

When measuring the durability of a moissanite ring vs diamond experts found that diamond has a hardness of 10 whereas moissanite has a hardness of 9.25-9.5 making it the second of the world’s hardest gems. 

This means that there’s no significant difference between diamond vs moissanite on the Moh Scale of Hardness as both of them are highly durable and have what it takes to resist tough conditions when worn daily or even occasionally, such as wearing James Allen diamonds for unmatched beauty.

If you’re searching for an alternative to diamonds, then buying a moissanite ring is your best option as it’s very tough against scratches with everyday use. 


When it comes to the clarity of diamond vs moissanite and which is clearer, experts found that moissanite has better clarity than diamonds. 

This can be seen in the small imperfections or inclusions that appear under the examination of moissanite vs lab diamond and natural diamond where moissanite wins for having minimal imperfections. 

It is worth noting that the clarity level in any type of diamond or gemstone affects its value. For instance, when comparing the price of lab grown diamond vs moissanite we find that their clarity level affects the price and value of both gems, so be careful when selecting engagement rings for their clarity scale, and we encourage you to check out James Allen diamond rings as they offer different clarity levels.

Also, it is noted by experts that lab-grown diamonds are clearer than natural diamonds, making them a top choice for many buyers seeking a very clear diamond stone.

Within a gemstone, color represents the natural pigment or absence thereof that is perceptible.

The human eye can’t always notice the difference in the color of diamond vs moissanite but labs can. 

Moissanite has a light yellowish color that is hard to notice when the stone is small to medium in size.

However, the bigger the moissanite stone, the more noticeable the yellowish color it reflects, so always keep the size of the stone in mind when opting for a new moissanite ring for your engagement. 

A diamond, on the other hand, could be colorless or yellowish, depending on the diamond’s color grade. For example, diamonds with lower grades (I, J, K and lower) can resemble a yellowish color.

Nevertheless, many diamonds are famous for their pure white appearance, which enables diamond rings to take the color of the skin naturally without any coloring in reflections. 

Discovering James Allen vs Blue Nile diamond rings options save you time and effort when choosing fancy colored diamond rings like purple, yellow, and pink. Although colorless diamonds are classic, Blue Nile colored diamonds are rapidly trending.


Describing brilliance in diamond vs moissanite involves capturing the way light reflects from within the gem, creating a radiant effect.

Moissanite is the most brilliant gem in the world, and diamonds come second among the shiniest stones for engagement rings worldwide. 

Moissanites reflect rainbow colors while diamonds reflect a pure white color and this difference between moissanite and diamond is the most prominent one of all the comparison aspects.

Love the reflection of rainbow colors on a moissanite diamond ring? We urge you to pick a moissanite ring with a rainbow reflection as it is more brilliant than diamonds when comparing moissanite rings vs diamond under sunlight.

While some individuals adore the vibrant, multicolored bursts produced by moissanite diamonds, others express concerns that the heightened brilliance of moissanite may result in a “disco-ball” appearance, particularly when exposed to sunlight.
