Gemstone Jewellery

Start with the colour you love and how you will wear it. Sapphire and ruby are the toughest and suit everyday rings. Aquamarine is cool and clean, and suits pendants and earrings as well as rings worn with care. Emerald and tanzanite are more delicate and suit occasion wear or protective settings.

See our guide above and our sapphire, ruby, emerald, aquamarine and tanzanite collections.

A sapphire is corundum, very hard and usually a deeper, richer blue. Aquamarine is beryl, paler and cooler, with a lighter blue-green tone, and it is slightly softer.

Sapphire is the better choice for a ring worn daily. Aquamarine offers a fresh, light blue, often with greater clarity, at a lower price.

A ruby is, as it is as hard as sapphire. An emerald can be, but it is more brittle and usually contains inclusions, so it needs a protective setting and a little more care.

If you would like a coloured engagement ring, tell us how you live and we will suggest a stone and setting. See engagement rings.

Strong, even colour makes a stone look richer. A pale stone looks delicate, and a deep one looks bold. Metal and surrounding diamonds change this: yellow gold warms, white metals cool, and a diamond halo brightens.

Colour also changes with light, so see it in daylight and indoors.

No. In most stones, the most valuable colour is a strong, vivid one of medium tone. A very dark stone loses its brightness and can be worth less. A pale stone is usually less valuable, though some, such as aquamarine, are prized for lightness.

Value also depends on clarity, size and origin.

Often, yes. Tell us the stone, colour, shape, size and budget, and we will search through our suppliers and show you options before you commit.

Use the enquiry form or WhatsApp.

Earrings and pendants are the easiest, because you do not need a size. A birthstone pendant or a pair of studs is a personal choice. For a bigger gesture, a ring with a diamond halo is a classic.

See our earrings, pendants and bracelets.

A solitaire has one stone alone. A halo surrounds the centre stone with small diamonds, which makes it look larger, adds sparkle and gives the coloured stone extra protection.

A halo works well with a coloured stone, because the diamonds frame the colour.

Yes. Yellow gold adds warmth, which suits emerald and ruby, and can make a blue sapphire look slightly greener. Platinum and white gold are neutral, keeping blue stones crisp.

We can show you the same stone in two metals at the showroom.

Yes. Many designs combine a coloured centre stone with diamond accents, and we can offer natural or lab-grown diamonds in a custom piece. Most of the diamonds in our ready-made pieces are described on the product page.

Ask us when you enquire.

Yes, with the right stone. A sapphire or ruby bracelet is tough enough for regular wear. Softer stones, such as emerald, are more likely to chip, so we would suggest them for occasions.

Check that the clasp is secure and the links are even. See gemstone bracelets.

Yes. Send us a photograph or sketch, tell us the stone and your budget, and we will advise and quote. We draw the design in CAD for your approval before we make it.

A bespoke piece typically takes three to four weeks and cannot be returned.

Sapphire and ruby, which are very hard and tough. Aquamarine is also good with sensible care. Emerald and tanzanite are better for occasions or for jewellery that is knocked less, such as earrings and pendants.

A protective setting helps any stone.

Emeralds are brittle, and they usually contain internal inclusions and are often treated with oil to improve their clarity. A hard knock can chip them, and ultrasonic cleaners and heat can damage the treatment.

Clean an emerald gently in warm soapy water, and avoid ultrasonic and steam cleaners.

It can be worn, but it is softer than sapphire and can scratch or chip. A protective setting and a little care help. Many people wear tanzanite rings for occasions and choose earrings or pendants for daily wear.

Avoid heat and ultrasonic cleaners.

Soak it in warm water with a few drops of mild washing-up liquid, brush gently with a soft toothbrush, rinse and dry with a soft cloth. Avoid harsh chemicals.

Have the claws checked once a year, which we do for free at our London showroom.

Carat is a weight in both, but different stones have different densities. A one-carat sapphire is smaller than a one-carat diamond in size, and an emerald is lighter and looks larger.

Compare the dimensions in millimetres.

No two natural stones are identical. Colour may vary a little within a stone and from one stone to another, and small inclusions are normal in many types. Photographs and screens vary.

We can send a video or show you the piece, so you see the true colour.

Most of our gemstone jewellery is set with natural stones, and the product page describes each piece. Some of the diamonds used as accents may be lab-grown or natural, and the page says which.

If you are unsure about a particular piece, ask us before you buy.

It depends on the piece. Diamonds in some pieces carry GIA or IGI reports, and the product page names them. Coloured stones in our ready-made jewellery are not always supplied with a laboratory report.

If you want a report on a coloured stone, tell us and we can source one with a report. We will confirm what you will receive for the exact piece.

Screens vary, so we cannot promise a perfect match. We photograph our pieces carefully and can send a video in natural light. You can also view the piece in the showroom.

Eligible ready-to-ship pieces can be returned within 30 days if unworn and undamaged.

Colour, clarity, origin and treatment drive the price. A vivid green emerald with few visible inclusions costs far more than a paler, more included one. Treatment also affects value.

Compare colour and clarity as well as size, and ask us to explain the difference.

Yes. Tell us the piece and we will send photographs and a short video in natural light, so you can judge the piece before you decide.

You can also choose in person: book an appointment.

Yes. Tell us your budget, stone and style, and we will propose a stone and setting that fit it, with a clear quotation. We can suggest ways to save, such as a slightly smaller stone or a different metal, without losing what matters to you.
