Every ring on this page is drawn live, not photographed. Choose the metal, the stone and the size, then turn it the way you would at a counter. When it's right, we make it.

Prices shown are guide prices. Each stone is priced on its own grade, and we'll confirm the exact figure with the stone in front of you before you pay anything.

True size

How big is one carat, really?

Product photos make every stone look the same size. Hold a bank card to your screen once, and we'll draw your ring on a finger at its real millimetre size. On a phone it's accurate enough to decide from.

Step 1. Calibrate your screen

Place any bank or ID card flat against the screen. Drag the slider until the dashed outline matches the card's edges.

Bank card85.6 × 54 mm

Using an estimate for now. Calibrate for real sizes.

The stones

Four stones, and the truth about each.

A jeweller who only tells you the good parts is selling, not advising. Every stone has a weakness, and knowing it is how you choose the right one for how you'll wear it.

How a commission works

From this page to your hand.

Nothing is paid until you've seen the actual stone. In person at the studio or on a video call with it on the tray, turned under the same lamp.

Specify it here

Your choices travel with your enquiry, so we start the conversation already knowing what you want.

See the stones

We pull three stones that match and show them to you in the studio or on video, with their grading reports.

Questions

Before you ask.

Do you ship internationally?

Yes, fully insured and signed for. Duties depend on your country and we'll tell you the likely figure before you pay the deposit.

I don't know their ring size.

Choose your best guess. We'll send a free plastic sizer with the wax model, and the first resize is free anyway.

Natural or lab-grown diamonds?

Both, and we'll show you both side by side. Lab-grown costs far less for the same look. Natural holds more of its value. It's always stated on the certificate.

How accurate is the true-size view?

Once calibrated with a card, it's within a few tenths of a millimetre on most screens. It shows the stone's width from above, which is what people see when it's on the hand.

Can I bring my own stone or redesign an heirloom?

Yes. Book a viewing and bring it. Reworking a family piece is some of the work we like most.

We'll pull three stones for you.
