Moissanite – Out of This World!

Although the moissanites being used in jewellery today are man-made in a lab, moissanite was originally a naturally-occurring element that didn’t originate on earth!

Moissanite was discovered by the Nobel Prize winning French chemist, Dr. Henri Moissan, in 1893. Taking samples from inside a meteor that landed in Arizona, he believed he had found diamonds and it wasn’t until 1904 that he realised his mistake and that this was a new mineral which he, of course, named after himself – Moissan-ite.

However, moissanite is so rare that scientists devised a way to create the stone in a lab. This led to the creation and use of the moissanite stone at a in jewellery from the mid 90s.

Features of Moissanite

Moissanite must be seen as a gemstone and not as an imitation diamond. Yes, there are similarities to their appearance but there are sufficient differences to tell them apart. A ruby or emerald is not a diamond but are still beautiful stones that most people would be happy to wear and have! Moissanite has its own features which make it unique and, in some ways, better than other stones.

Near perfect appearance

As all moissanites in jewellery are lab grown, they have few if any inclusions or imperfections. Their hardness, second only to diamonds on the Mohs scale, means they are less likely to scratch or scuff than other gemstones. Moissanites are cut to best bring out their own unique features and not to try make them look like a diamond!

Mohs Hardness Scale

  • Diamond – 10
  • Moissanite – 9.25
  • Ruby & Sapphire – 9
  • Emerald & Aquamarine – 7.5-8

Ethically made and conflict-free

Unlike any mined stone, Moissanite is only made in labs. This means it is fully traceable so you can be confident about where your ring came from.

More brilliant than diamond!

Yes, a moissanite stone is more brilliant than a diamond – i.e., it’s shiner. This makes the moissanite the most brilliant gemstone in the world!

In terms of colour, our moissanites are defined as “colourless”, which is the purest of moissanite colours (comparable to D or E of diamonds).

Diamonds and moissanites also reflect light differently so it is a matter of deciding which one you prefer.

Moissanites are lower in price

A major plus when it comes to moissanites is that they are a fraction of the cost of diamonds. Unlike with diamonds, the only factors that alter the price are size and shape.

Diamonds Vs Moissanites

Can you tell the difference between Moissanite, Natural Diamond and Lab Diamond?

Moissanites are not diamonds and diamonds are not moissanites. They are completely different stones that have some similarities. They can be difficult to tell apart at times but when side by side or to the trained eye, it is possible to see the difference. There are also differences in terms of their properties.

Grading of Moissanites

Moissanites are not graded in terms of the 4 Cs– cut, colour, clarity, and carat weight, of diamonds. These measures do not translate across for moissanites, but because of moissanites’ consistent quality – it is unlikely you will find a moissanite with big inclusions or a tinted colour. This is because these stones are formed in the quality-controlled environment of a lab. The differential across moissanites is usually due to changes in size.

The 2 Hardest Minerals on Earth

On the Mohs Scale of Hardness, used to determine the hardness of all gemstones, a diamond ranks a maximum of 10 and the moissanite is in second place at 9.25. It is therefore more durable than most gemstones such as a ruby or sapphire.

Buying Moissanite Stones – Ireland

It’s rare for the average person to notice the difference between a diamond and a moissanite stone simply by looking at it. However, it’s important to keep in mind that moissanites aren’t diamonds. For some, diamonds carry more meaning and see it as of great importance for their engagement ring to have a diamond whereas others just want a ring that suits them. Moissanites are a great alternative for those looking for a lower price. They are also a great ethical choice as they are all lab created.

The Difference Between a Diamond and a Moissanite

There are some differences between diamonds and moissanite. Moissanites are a 9.25 on the hardness scale. This makes the moissanite one of the hardest substances used in jewellery (only behind diamonds). Diamonds are the hardest substance and score a 10.

·       Brilliance

There are also differences in the stones’ brilliance. A moissanite stone gives off a more spectral shine; it disperses light exceptionally well and has a higher brilliance than a diamond. A diamond reflects light in three different ways, giving it its unique sparkle.

·       Price

There is a vast difference in price between a diamond and a moissanite stone. A diamond’s price is dependent on its cut, clarity, and other features. A moissanite stone’s price changes with alterations in size and type of moissanite stone.  So, as a result, a moissanite stone is a fraction of the cost of a diamond.

·       Moissanite Carat, Size and Weight

Moissanite weighs less than a diamond and is measured in millimetres, not carats. Below is a table showing some of the equivalents of the most commonly used sizes in engagement rings.

Moissanite size* Diamond Carat*
5.0 mm 0.50 ct
6.5 mm 1.00 ct
7.0 mm 1.3 ct
7.3 mm 1.50 ct
8.0 mm 2.00 ct
8.5 mm 2.50 ct
9.0 mm 3.00 ct

·       Clarity and Imperfections/Inclusions

Moissanite often has a higher clarity than a diamond. Because they are made in a lab in controlled conditions, efforts are made to minimise their inclusions and flaws.

Negatives of Moissanites

There are some negatives to choosing a moissanite stone over a diamond. A diamond is a colourless stone in its natural state, whereas a moissanite stone can have a grey or yellow hue. Also, although moissanites have a strong brilliance, in certain light, they can emit a rainbow-like refraction that some people dislike while others admire.


In conclusion, a moissanite stone is an excellent alternative to diamonds. If, due to budgetary constraints, a diamond is unsuitable, a moissanite stone will prove a viable option. All the rings available from Bespoke Diamonds are available with a moissanite stone.

Does Moissanite lose its shine or brilliance?

As moissanite is almost as hard as diamond, it will not lose its sparkle over time. The clarity and colour of the stone also won’t change. If any ring (moissanite, diamond or other gemstone) is not cleaned regularly, they may get dirty which will hide the ring’s sparkle. Regular cleaning is advised.
