How much does a bespoke engagement ring cost in Hatton Garden?

A complete bespoke engagement ring at Hatton Garden Bespoke Jewellery starts at £2,000, which covers the setting and the centre stone together. Settings on their own start at £910. Most commissions land between £3,000 and £12,000.

That is the short answer. The rest of this page explains what moves the number, because the useful question is not what a ring costs but what you are actually paying for and where the money goes furthest.

The three things that set the price

A bespoke ring is built from three costs, and you control all of them at the design stage.

1. The centre stone

This is almost always the largest single cost, and it is the one that moves most. Price rises with the 4Cs, and it does not rise in a straight line. Carat weight steps up sharply at round numbers, so a 0.90ct stone can cost noticeably less than a 1.00ct of the same grade while looking a fraction of a millimetre different.

We have not printed a table of stone prices here, deliberately. Diamond prices move with the market, and a figure published in one month is misleading by the next. Our diamond search shows live prices on graded stones as you filter by shape, carat, colour and clarity, which is more use than any number we could type.

What we can tell you is where the value sits. Hold cut high, because it governs how much a stone sparkles. Treat G to J colour and VS clarity as the value band, since neither is visible to the naked eye once set. Then let carat flex to suit the figure you have in mind. Laboratory-grown diamonds typically cost less per carat than natural, so the same budget reaches a larger or higher graded stone.

2. The setting

Our settings run from £910 to a little over £8,000, and the spread comes down to metal and complexity.

A plain solitaire sits at the lower end. At current metal prices, platinum usually costs less than 18ct gold and more than 9ct or 14ct, and each setting's page shows its price in every metal. Detail adds cost in proportion to the hand work it needs: a halo or a pavé band means dozens of small stones individually set, and a three stone design carries two additional stones as well as the centre.

Because our settings are priced individually and shown with the stone, you can see the effect of each choice as you make it rather than waiting for a quote.

3. The design work

CAD design is from £300. The fee covers the CAD work, it is non-refundable, and it comes off the price of the ring when you go ahead. It is not an additional charge on top of the finished piece.

The reason it exists is straightforward. CAD design is real work done before anything is committed, and charging for it means we can spend proper time on the drawing rather than rushing to a sale. Every ring is designed in CAD and hand finished at our bench inside The Goldsmiths' Centre, then hallmarked at the London Assay Office, which is included in the price rather than added at the end.

What you get at each level

£2,000 to £3,000

A classic solitaire in gold with a smaller natural stone, or a larger laboratory-grown one. This is the range for a simple, restrained ring. You are choosing proportion over carat weight, and a well cut half carat in a clean setting reads better on the hand than a bigger stone in a compromised one.

£3,000 to £12,000

Most of what we make. Expect a centre stone around three quarters of a carat upwards in natural, or larger in laboratory-grown, in platinum or 18ct gold, with a solitaire, halo or three stone setting. There is room here for detail: pavé shoulders, a hidden halo, tapered baguettes.

Above £12,000

Larger natural stones with premium colour and clarity, or elaborate hand set work. This bracket also covers redesigns built around a significant inherited stone, where the architecture is new but the diamond has a history.

How long it takes

Three to four weeks from the moment you approve the CAD design. Allow four to six weeks end to end from the first conversation, which leaves room for choosing the stone and revising the drawing.

Where the money goes

You receive a full, itemised quote before anything is made. You are also buying the ring you asked for rather than the nearest thing in the tray, which means none of your budget goes on features you did not want.

A Hatton Garden address can simply be a retailer buying finished stock. Our guide to buying an engagement ring in Hatton Garden covers how to tell the difference.

How we quote

The first consultation is free and without obligation, in person at the studio or over the phone. We work through budget, stone preferences and design direction, then price the ring before anything is made. Nothing is ordered until you have approved the CAD render.

We ask about budget early and directly, because it saves everyone time. A jeweller who knows your figure can tell you in five minutes what is achievable at it.

Frequently asked questions

What is the cheapest bespoke engagement ring you make?

A complete ring starts at £2,000 for the setting and centre stone together. A setting on its own starts at £910 if you are supplying the stone or buying it separately.

Is the design fee extra?

Only if you decide not to go ahead. CAD design is from £300 and is paid before we start drawing. If you go ahead, the whole fee comes off the price of the ring. If you do not, the fee is not refunded. When you approve the CAD design, a 50% deposit is due, less the fee already paid, and it is non-refundable once production begins. The balance is payable before collection or delivery.

Can I use a diamond I already own?

Yes. Inherited and family stones are a common brief, and we design the new setting around the stone you have. We will tell you honestly if the stone is not suited to the design you want.

Does the price include hallmarking?

Yes. Every piece we make above the legal exemption weight is hallmarked at the London Assay Office, and that is inside the quoted price, not added afterwards.

Why do two Hatton Garden jewellers quote different prices for the same ring?

Usually because the specification is not actually the same. Hold carat, colour, clarity, grading laboratory, metal and setting style still, and the only variable left is the maker. Then you are comparing what you meant to compare.
