The Brilliant Story of Moissanite: History, Beauty & Extraordinary Sparkle

Few gemstones have an origin story quite like moissanite.

Its story begins in 1893, when French chemist Henri Moissan discovered tiny crystals of silicon carbide while studying material from the Canyon Diablo meteorite site in Arizona. Initially mistaken for diamonds, the crystals would eventually prove to be something quite different.

The mineral was later named moissanite in Moissan's honour.

More than a century later, moissanite has moved from scientific curiosity to a highly desirable jewellery stone, celebrated for exceptional brilliance, colourful fire and impressive durability.

Yet calling moissanite simply a diamond alternative misses much of what makes it interesting.

Moissanite has its own chemical composition, optical personality and extraordinary history. For many jewellery lovers, that individuality is precisely the attraction.

What Is Moissanite?

Moissanite is the gemstone form of silicon carbide (SiC).

Naturally occurring moissanite is extraordinarily rare. The tiny quantities found in nature aren't a practical source for the jewellery industry, so the moissanite used in modern jewellery is created under controlled laboratory conditions.

That distinction matters.

Lab-created moissanite isn't glass, cubic zirconia or synthetic diamond. It is silicon carbide with its own identifiable gemological and optical properties.

Those properties are responsible for the spectacular appearance that has made moissanite increasingly popular in engagement rings and fine jewellery.

If you'd like to see how those properties translate into different cuts and sizes, explore our loose moissanite collection, where you'll find a broad selection of shapes rather than being restricted to the traditional round brilliant.

Why Does Moissanite Sparkle So Much?

Sparkle is where moissanite becomes particularly interesting.

When light enters a faceted gemstone, its optical properties and the quality of its cut influence how that light travels through the stone and returns to your eye.

Moissanite is renowned for producing intense brilliance accompanied by flashes of spectral colour known as fire.

Under sunlight, spotlights and other directional lighting, a beautifully cut moissanite can produce flashes of red, orange, yellow, green, blue and violet.

That rainbow fire is one of moissanite's defining characteristics.

Some buyers want a gemstone with a more restrained optical personality. Others fall in love with moissanite precisely because they want serious sparkle.

For the classic expression of that look, explore our round brilliant cut moissanites, where the symmetry and faceting of the round brilliant are designed to make light performance the star of the show.

Is Moissanite a Diamond?

No — and it shouldn't be sold as one.

Diamond and moissanite are different gemstones.

Diamond consists of carbon, while moissanite is silicon carbide. Their optical properties differ, and a trained gemologist can distinguish between them.

They can certainly have a similar overall aesthetic, particularly when both are colourless and fashioned into familiar cuts such as round, oval or cushion.

But treating moissanite merely as an imitation diamond undersells the gemstone.

A much better question is:

Which gemstone has the appearance, properties and value that you prefer?

Moissanite vs Diamond: What's the Difference?

Both gemstones can make spectacular jewellery, but there are meaningful differences.

Brilliance and Fire

Both diamond and moissanite can be exceptionally brilliant.

Moissanite is particularly celebrated for its colourful fire, which can become very noticeable under strong lighting. Diamond produces a different balance of brilliance, fire and scintillation.

If you enjoy a gemstone that comes alive under changing light, moissanite can be extraordinary.

Durability

Diamond scores 10 on the Mohs hardness scale.

Moissanite is also exceptionally hard, at approximately 9.25, giving it excellent resistance to scratching and making it well suited to jewellery designed for regular wear.

Hardness isn't the only factor affecting jewellery durability — the metal, setting and design matter enormously — but moissanite's hardness is one reason it works so well in engagement rings and everyday jewellery.

Price

Price is one of the most obvious differences.

Moissanite allows buyers to achieve impressive size, brilliance and durability at a substantially different price point from a comparable diamond.

But describing that simply as cheap gets the proposition wrong.

The real advantage is choice.

A buyer might choose a larger centre stone, put more of the budget into an elaborate setting, choose several stones rather than one, or simply spend less without sacrificing the dramatic visual impact they want.

Origin

Most jewellery-quality moissanite is laboratory-created because natural moissanite is far too rare to supply the jewellery industry in meaningful quantities.

That makes its origin fundamentally different from a mined natural diamond.

Is Moissanite Durable Enough for an Engagement Ring?

Yes.

An engagement ring isn't jewellery that spends its life safely inside a box. It can be worn thousands of hours every year, encountering desks, bags, clothing, door handles and everything else daily life puts in the way of your hands.

That makes durability important.

Moissanite's high hardness and resistance to scratching make it an excellent candidate for frequently worn jewellery.

However, no gemstone or jewellery setting is indestructible.

Prongs can become damaged. Bands can distort. Stones can become loose. Even exceptionally durable gemstones deserve sensible treatment.

For jewellery worn every day, periodic inspection of the setting is worthwhile — particularly with larger centre stones and delicate prong settings.

Does Moissanite Come in Different Colours?

Absolutely.

Colourless moissanite remains a favourite for engagement rings and classic jewellery, but limiting moissanite to colourless stones ignores one of the most exciting parts of the category.

For something less conventional, explore our coloured moissanite collection, where colour gives this already distinctive gemstone an entirely different personality.

Green moissanite, for example, creates a dramatically different appearance from a colourless stone. Our emerald green princess cut moissanites combine vivid colour with the clean, angular geometry of a princess cut.

For someone who wants jewellery that doesn't look like everyone else's, coloured moissanite deserves serious consideration.

How to Choose a Moissanite

There isn't one universally “best” moissanite.

The right stone depends on the look you're trying to achieve.

Start With the Cut

Cut has an enormous influence on a faceted gemstone's appearance.

Good proportions and faceting help determine how light moves through the stone and returns to the eye. A beautifully performing stone can be far more compelling than a larger stone with mediocre cutting.

Don't choose based solely on size.

Choose with your eyes as well as the specification sheet.

Choose a Shape That Suits You

This is where moissanite becomes fun.

Your choices aren't limited to the classic round brilliant. Browse our complete loose moissanite collection to compare different shapes and discover how dramatically a change in cut can alter the personality of a stone.

For maximum classic sparkle, a round brilliant moissanite is difficult to ignore.

For something angular but still intensely brilliant, consider a radiant cut moissanite. Its rectangular silhouette combines beautifully with brilliant-style faceting, producing a more contemporary appearance.

For a softer elongated silhouette, a pear cut moissanite combines a rounded end with a distinctive point and can make a particularly elegant centre stone.

Round, radiant and pear can all be beautiful.

They simply create very different jewellery.

Think About Colour

If you're aiming for a classic colourless aesthetic, colourless or near-colourless moissanite will usually make the most sense.

If individuality matters more, don't automatically dismiss colour.

A vivid green, grey, champagne or other coloured stone can transform a conventional jewellery design into something far more personal.

Don't Automatically Buy the Biggest Stone

One of moissanite's advantages is that it gives you considerably more freedom over size.

Use that freedom intelligently.

Bigger isn't automatically more sophisticated.

The stone should work with the wearer's hand, the proportions of the setting and the overall design. A beautifully proportioned centre stone will generally look more considered than simply choosing the largest size available.

Does Moissanite Look Fake?

A good moissanite doesn't look “fake.”

It looks like moissanite.

The question usually arises because moissanite is constantly compared with diamond. If someone expects every colourless faceted gemstone to behave exactly like a diamond, moissanite's distinctive fire can reveal that it is a different material.

But different doesn't mean fake.

Emerald doesn't need to pretend to be sapphire. Sapphire doesn't need to pretend to be diamond.

Moissanite deserves the same treatment.

Choose a beautiful moissanite because you appreciate what it is — not because you're hoping nobody discovers what it isn't.

How to Care for Moissanite Jewellery

Even an exceptionally brilliant gemstone can become dull-looking when its surface is coated in everyday grime.

Skin oils, hand creams, soap and cosmetics can leave a film on jewellery that reduces the amount of light reaching the gemstone.

Routine cleaning is straightforward.

Use warm water with a small amount of mild dish soap and allow the jewellery to soak briefly. Gently clean around the stone and setting with a very soft toothbrush, rinse thoroughly and dry using a clean, lint-free cloth.

Pay particular attention to the underside of the gemstone, where residue can accumulate unnoticed.

Avoid unnecessary exposure to harsh chemicals and store jewellery carefully so pieces don't continually rub against one another.

For frequently worn rings, occasional professional inspection is also sensible. The gemstone may be extremely hard, but the metal and setting still require care.

What Does Moissanite Look Like in Finished Jewellery?

A loose stone tells only half the story.

Setting, metal colour, stone size and surrounding design can completely change the way moissanite presents itself.

A solitaire can make the centre stone the undisputed focus. A halo can increase visual presence. Earrings introduce movement and flashes of light around the face, while tennis jewellery transforms individual stones into a continuous line of sparkle.

If you'd rather see moissanite already incorporated into finished designs, browse our moissanite jewellery collection.

For a particularly dramatic expression of moissanite's brilliance, a round brilliant moissanite tennis necklace creates an entirely different visual effect from a single centre stone, using repeated round brilliant stones to produce continuous sparkle.

Why Has Moissanite Become So Popular?

Moissanite occupies an interesting place in modern jewellery.

It combines durability, intense optical performance, numerous cuts and colours, and considerably more flexibility around stone size and budget.

But perhaps its biggest advantage is choice.

Jewellery buyers no longer have to follow one formula for what an engagement ring or meaningful piece of jewellery is supposed to contain.

Some people will always want natural diamonds.

Others prefer laboratory-grown diamonds.

Some fall in love with sapphires, emeralds or other coloured gemstones.

And others choose moissanite because its combination of brilliance, fire, durability and individuality is exactly what they were looking for.

That's a much better reason to buy a gemstone than simply because it's less expensive than another one.

Discover Your Moissanite

The best way to understand moissanite is to see how dramatically its personality changes with cut, colour, size and setting.

If you want to choose the gemstone first, start by comparing different shapes and sizes in our loose moissanite collection.

If you're looking for something less conventional, discover our coloured moissanites.

And if you'd rather see the gemstone already transformed into a finished piece, explore our moissanite jewellery.

Don't choose moissanite because you think it's the stone you're supposed to buy instead of something else.

Look at different cuts. Compare colour. Watch the stones under changing light. Decide how much sparkle you enjoy.

Then choose the one that makes you want to look at it again.

That's what a great gemstone should do.
