Diamond Engagement Rings

Elongated shapes. Oval, pear, marquise and emerald cut spread their weight over a longer outline, so they show more surface than a round brilliant of the same weight, and they lengthen the finger too. A round is deeper for its width, so more of its weight is hidden below the surface, although it returns the most light.

If face-up size is the priority, compare an oval or pear with a round at the same budget. The measurements in millimetres on each listing tell you more than the carat weight.

Both suit an oval, but for different reasons. On short or wide fingers an oval lengthens the line of the hand. On long fingers it sits comfortably without looking narrow, especially in a slightly wider oval.

Set east-west or north-south, it changes the effect. The way to settle it is to try a few on. You can compare oval rings in our showroom, or browse the oval collection first.

A solitaire is a single diamond in a plain setting. A halo surrounds the centre stone with a ring of small diamonds, making it look larger and adding sparkle. A hidden halo places those small diamonds beneath the centre stone so they show only from the side, keeping the top view clean.

Solitaires are the easiest to clean, halos give the most visual impact, and hidden halos sit between the two. See solitaire, halo and hidden halo rings.

An emerald cut has long, open step facets that create flashes of light rather than sparkle. Because the facets are so clear, colour and clarity are easier to see than in a brilliant cut, so it is worth choosing a little higher on both.

Look at the length-to-width ratio, which sets how slim or square the stone appears, and choose a setting that protects the corners. Browse emerald-cut rings.

Yes, when they are made well. The smaller stones sit lower and are protected by the setting, and many people find a side-stone ring more secure on the hand than a tall solitaire. Check that the side stones are matched in colour and cut to the centre stone and set flush, and be aware that rings with more stones need a little more cleaning.

Yes. Send us a photograph, a sketch or a design you have seen, and our team will tell you what is possible, which diamond shape and metal would suit it and what it would cost. We design and make in Hatton Garden, and we can adapt an existing design, change the metal or stone, or draw something new in CAD for your approval before we make it.

Start with the enquiry form or send us a message on WhatsApp.

Yes. A lab-grown diamond has the same chemical composition, crystal structure and hardness as a mined diamond, and it is graded on the same colour, clarity, cut and carat scale. The difference is origin: it was grown in a controlled environment rather than formed in the earth.

That origin is why it costs less for the same grade. See lab-grown versus natural diamonds.

Decide what matters most. If you want the most size or the highest grades for a given budget, lab-grown usually delivers more. If you value a diamond formed by nature and are comfortable paying more for it, choose natural.

Side by side at the same grades they look and behave the same, and both can be set in any design we offer. We sell both, so we have no reason to steer you. Tell us your budget and we will show you the same ring in each so you can compare.

GIA grades the natural diamonds we sell, and IGI grades the lab-grown ones. Where a ring is sold as certified, the product page names the laboratory and report number, so you can check it on the laboratory's own website.

A report verifies the diamond's grades and measurements. It does not describe the ring or its metal, and not every ring or small side stone carries one, so read each listing. See GIA and IGI reports explained.

Tell us the ring and your budget and our team will recommend the options that give you the most value, and explain what each step in price buys. You see the report, where there is one, and the price before you commit.

There is no pressure and no obligation to buy.

Yes. We can lay stones and rings side by side at our showroom, or send you videos and reports so you can compare them at home.

Carat is a weight, not a measurement. A shallow-cut diamond spreads more weight across its top and looks larger but may be less brilliant. A deep one hides weight below the surface and looks smaller. Shape matters too, as an oval or pear looks bigger than a round of equal weight.

Compare the millimetre measurements and the cut grade where one is given, rather than carat alone.

Platinum is white, dense and holds its colour and its prongs well, so it is the usual choice for a ring worn every day for decades. 18K gold has a richer colour and is a little softer. 9K is the hardest-wearing of the golds and the most affordable, with a paler, less pure colour.

All three are offered across this collection. See gold versus platinum.

A little. Yellow gold reflects its warmth into the diamond, so a near-colourless stone looks slightly warmer than it does in platinum or white gold. Many buyers like this, and it means you can choose G or H colour with confidence. If you want the whitest possible look, choose platinum or white gold, or a higher colour grade.

Rose gold adds a pinker warmth. We can show you the same ring in each metal.

Borrow a ring she already wears on the correct finger and measure the inside diameter, or trace it on paper and send us the outline. A friend or family member may know her size. If you cannot find out, choose a common size and rely on our free resizing for life on eligible rings.

Our ring size guide explains the methods.

Yes. Resizing is free for life on eligible rings. Most solid-band rings can be adjusted by a size or two either way, and some designs, such as full eternity bands, cannot be resized easily. Resized and made-to-order items cannot be returned, so it is best to get the size right if you can.

Tell us the ring you are interested in and we will say whether it can be resized.

Yes. A high-set stone or a halo can stop a straight band lying flat, so we can shape the engagement ring's profile or make a curved or notched wedding band to fit around it. We can do this for rings from Amada or from elsewhere.

Bring the ring to Hatton Garden or send photographs. See our wedding and eternity rings.

A lower setting sits closer to the finger, so it catches on clothes and gloves less, feels more secure and allows a wedding band to sit flush. The trade-off is less light entering the diamond from below, and a little less height on the hand. Bezel and low-set claw designs are the most protective.

If you work with your hands or want a ring that lasts, ask us for low-profile options.

The collection runs from a few hundred pounds to several thousand, and a large share of it falls under £2,000. Around £1,000 you will mostly find lab-grown solitaires and side-stone rings. At £2,000 there is a wider choice of larger lab-grown stones, halos and platinum settings. At £3,000 and above you can choose larger stones, higher grades and natural diamonds.

The right answer depends on shape and metal, so tell us your figure and we will show you real options.

No. We tell you what each option offers and recommend what is right for you, with the aim of giving you the most value for your money.

Our pricing page explains how we price.

We source diamonds through the trade and make the rings ourselves, so there are fewer layers between the stone and the customer. Our listings show the metal, carat weight and quality, and we explain how we price on our pricing page.

We do not claim a set percentage saving against other retailers, because grades and settings vary. We encourage you to compare like for like.

The product page and the delivery estimate at checkout show which applies, and the ready-to-ship collection gathers rings we hold. Many styles in this collection can also be made in a different metal or stone size.

If you are not sure, ask us on WhatsApp and we will confirm for the exact ring.

Many can. Ready-to-ship rings usually dispatch in one to three working days, and selected made-to-order styles are usually expected in about ten days. This depends on availability, finishing, hallmarking and courier timing, and is not a guarantee.

If you have a proposal date, tell us before you order and we will confirm what is realistic for that ring.

Typically three to four weeks from approval of the design. That includes CAD drawing, sourcing or matching the diamond, casting and setting, polishing and hallmarking.

We will give you a date for your own ring when we quote. Bespoke rings are made for you and cannot be returned, so we share a design drawing for approval first.
