Moissanite vs. Diamond, what is the difference?

Updated: Dec 12, 2021

In the world of colourless gemstones, there is a lot to choose from and consider when selecting the perfect gift for yourself, a loved one or creating a custom engagement ring.


My clients, family and friends often ask me about the difference between diamonds and other gemstones that look like them.

One of diamond's look-a-likes is Moissanite.


It was first introduced to the market in 1998 and has become increasing popular in the last 10 years.


Moissanite is a much more affordable option compared to a diamond but I have to mention that the difference in value is also significant.

Let's take a closer look at Moissanite:


  • The full name for Moissanite is Synthetic Moissanite

  • It is man-made stone created in a lab

  • Natural moissanite does exist in nature and was discovered in 1893 but there was never enough of it to be used commercially

  • All moissanite currently on the market is synthetic

  • Moissanite is know as a diamond simulant, meaning it looks like a diamond but does not possess the same physical or chemical properties

  • Although Moissanite looks similar to a diamond from afar, it's value is significantly lower than a diamond's

Is Synthetic Moissanite the same thing as a Synthetic Diamond?


No.


Although they are both lab-created, they are completely different stones.


Synthetic Diamond is a man-made / lab created stone that possesses the same physical and chemical properties as a natural diamond.


Synthetic Moissanite is a different stone all together.


Diamond (below) is a natural stone, created by nature.

I know it gets a little confusing!

Durability


In terms of hardness, Moissanite scores a 9.5 out of 10 on Moh's scale.


It is harder than all coloured gemstones and almost as hard as a diamond which scores a 10.


In terms of durability, diamond and moissanite are both great for everyday-wear.

Does Synthetic Moissanite really sparkle more than a diamond?


Synthetic Moissanite has a higher refractive index than a diamond and shows extreme fire, compared to a diamond’s moderate fire. Often, it also has a slightly yellowish colour.


In other words...


These properties create a “disco ball’’ effect in Moissanite which according to some, appears to “sparkle” more than a diamond.


Whether you agree, is up to you!

How much does a Moissanite cost?


As you may know, the cost of a diamond depends on the 4Cs (clarity, colour, cut and carat weight).


When it comes to Moissanite, it is typically the size that affects it's price.


Most Moissanite is the same quality and has a similar price per carat, so you don't have to worry about choosing a quality like you do with diamonds.


Overall, Moissanite is dramatically lower in price than a diamond and holds a very different value.

Moissanite is a great option if you are looking for a large stone at an affordable price. It is also available in a variety of shapes.


If you are looking for a colourless stone that's not a diamond, another great option is a white sapphire (below). The latter is a natural stone and a more affordable option compared to a natural diamond.


Although some white sapphires are similar in price to Synthetic Moissanite and don't show as much sparkle, white sapphires are still considered to be of higher value.

Pro Tip: When purchasing any gemstone, I highly recommend considering it's value over price
