A 4.1 carat moissanite, graded D for colour and VVS1 for clarity, on a band of solid 925 sterling silver finished in rhodium, the same plating jewelers apply to white gold.

Moissanite has more fire than a diamond. That is measured, not marketing: its dispersion is 0.104 against a diamond's 0.044, which is why it throws red, green and blue where a diamond mostly returns white. At 9.25 on the Mohs scale it is harder than sapphire and well above emerald, which is what makes it sensible to wear every day.

Every stone is GRA certified. The certificate ships with the ring, recording its weight, colour, clarity and cut against a reference number, in a gift box with a care card.

Covered by our Lifetime Stone Guarantee. If the stone ever dulls, clouds or chips in normal wear, we replace the ring.

Fire

It throws colour a diamond cannot.

Step into sunlight and your ring flashes red, green and blue where a diamond gives back mostly white. That is dispersion, a measured property, and moissanite has more of it than any diamond ever cut: 0.104 against 0.044.

It is the flash people catch from across a room. It is also the reason the stone reads as alive rather than merely expensive.

Colour

Icy white, with nothing above it.

Stone colour runs from D, completely colourless, down to Z, visibly yellow. Most stones sold as white sit several letters down and read faintly warm the moment they are set against silver.

Yours is graded D, the top of the scale. It stays bright on your hand in daylight, in candlelight, and in every photograph anyone takes of it.

Clarity and cut

Flawless to your eye. Every time you look.

VVS1 means a trained grader has to hunt for an inclusion at ten times magnification. At arm's length you will never find one.

Cut to Excellent on top of that, so the light that goes into the stone comes back out at you instead of leaking away through the bottom. That is what makes a stone look awake rather than glassy.

Durability

Put it on and leave it on.

At 9.25 on the Mohs scale, moissanite is harder than sapphire and well above emerald, a shade under diamond. It will not scratch dull at the sink, at the gym, or against a steering wheel.

This is a ring you wear every day for decades, not one you keep for occasions. We guarantee the stone for as long as you own it.

The arithmetic

The same look, without the five figure invoice.

A mined, D colour, VVS1, Excellent cut diamond at this weight runs well into five figures before anyone has set it in anything.

On your hand, across a table, in a photograph, the difference is invisible. What differs is the supply chain behind it. Ours is a laboratory, which is also why the grades come out consistent rather than lucky.

What arrives

GRA certified, so you can prove what is on your hand.

Every stone is GRA certified. The certificate travels with the ring, recording its weight, colour, clarity and cut against a reference number.

That is the difference between being told a stone is D colour and VVS1 and being able to show it. You know exactly what you own, and so does anyone who asks.

Lifetime Stone Guarantee

If it ever dulls, you get a new ring. For as long as you own it.

Moissanite does not cloud, yellow or lose its fire with age, and we are willing to put that in writing for life. If it ever happens, or if the stone chips or cracks in normal wear, we replace the ring. For the first twelve months the setting is covered too, and after that a setting failure gets you a replacement at half price.

Not covered: loss, theft, impact damage, chemicals, third-party resizing, or wear to the rhodium finish. Read the full terms.

Questions

Everything people ask before they buy.

Is moissanite a real gemstone?

Yes, and not a simulant or a coating. Moissanite is silicon carbide, first identified by the chemist Henri Moissan in a meteorite crater in Arizona in 1893. Natural moissanite is far too rare to cut into jewellery, so the stones in our rings are grown in a laboratory, chemically and optically the same material. You are wearing a real gemstone. Just not a rare one, which is the entire point.

Will it pass a diamond tester?

On the basic thermal tester most jewellers reach for first, usually yes, because moissanite conducts heat much the way diamond does. It will not pass a modern dual thermal and electrical tester, and it will not pass a gemologist. We tell you that up front. The point of this ring is that it looks like a diamond on your hand, not that it has to pretend to be one.

Will it cloud or go dull over time?

No. Moissanite is chemically stable and does not cloud, yellow or lose its fire with age, and we back that with the Lifetime Stone Guarantee. If it ever happens, you get a new ring. The one thing that does change is the rhodium finish on the band, a surface plating that softens with wear exactly as it does on white gold, and any jeweller can redo it.

How does it compare to a diamond on hardness?

9.25 on the Mohs scale against a diamond's 10, which puts it above sapphire and far above emerald. In practice the gap between 9.25 and 10 is one you will never meet. This is a stone you can wear through the washing up, the gym and twenty years of ordinary life without babying it.

What is the GRA certificate?

Your stone's certificate from the Gemological Research Association. It ships in the box with the ring and records the weight, colour, clarity and cut against a reference number.

It means the grades on this page are documented rather than claimed. Every Baffour stone is certified before it is set.

What if the size is wrong?

Exchange it within 30 days for either of the other two sizes and we pay the return postage. If none of the three fit, send it back inside the same window for a full refund. There is no version of this where you are stuck with a ring that does not fit.

Is the band solid silver?

Solid 925 sterling with a rhodium finish on the surface, never plated base metal. Rhodium is the same finish jewelers apply to white gold, and like all rhodium it wears over time and can be redone by any jeweller.
