Choosing a lab-grown diamond ring starts with one question: one diamond at the centre, or a row of them across the band? A centre-stone ring is the natural choice for an engagement. You pick the shape first, then the carat weight, usually between 1 and 4 carats, with prices from AED 4,530. An eternity band sets its diamonds in a continuous line and comes in one fixed weight, from about 3 to 6.7 carats, up to AED 12,520. It works on its own or stacked beside an engagement ring.
Whichever you choose, the diamonds are graded EF for colour and VVS to VS for clarity, with an Excellent cut, and the ring is made in 18K white, yellow or rose gold in sizes 49 to 62. We don't keep finished stock, so your ring is made after you order it.
Shape is the first decision, because it changes the character of a ring more than carat weight or gold colour does. Our centre-stone rings come in six shapes, plus one two-stone design:
If you already know this is an engagement ring, most of these designs also sit in our Bridal collection.
Carat is a weight, not a size, so two 2-carat rings can look quite different on the finger. Marquise, pear and oval stones spread their weight over more surface than a round, so if you want the diamond to look as large as possible for your budget, start with those.
Moving up in carat weight costs less than you might think. On the Lumière, going from 1 to 4 carats adds AED 4,180. Centre stones above one carat also come with an IGI certificate, as well as the YAZ & Co Authenticator that records your stone and gives the ring its own serial number. Our Diamond Guide explains how cut, colour and clarity affect what you see.
An eternity band runs a line of matched diamonds across the top of the ring. Worn alone or beside a centre-stone ring, it doubles as a wedding or anniversary band. We make one in each main shape:
To build a stack, match the band to the shape of your centre stone. The Royale Eternity sits naturally with the Aura, the Radiant Eternity with the Althea, and the Prestige Eternity with the Grace. The tennis rings match our other tennis pieces by stone size too. The Majesté's 5 mm diamonds are the same size as those on the Majestic Tennis Bracelet and Majesté Tennis Necklace, and the Éternité ring pairs with the Éternité Tennis Necklace. You'll find them all in Tennis Classics.
Two rings sit outside these groups. The Twin Norvia Ring (about 3.27 ct) arranges round diamonds in a layered design and is part of our Bridal collection. The Majesty Bloom Ring (about 2.62 ct) gathers them into a bolder, more sculptural setting and belongs to the Signature collection.
Our rings come in sizes 49 to 62. These measure the inside circumference in millimetres, the European system, so if you know your size in US terms, the range runs from roughly a US 5 to a US 10. The Ring Size Guide has the full chart and two ways to measure.
Measure late in the day, when your fingers are at their largest, and if you're between two sizes, take the larger one. Take extra care with eternity bands. A continuous row of diamonds leaves no plain metal to cut and rejoin, so most can't be resized later. And because every YAZ & Co ring is made to your specifications, it can't be exchanged for another size once you've approved the design. If you're unsure, our boutique team can size you free of charge.
Production takes 15 to 20 business days once payment is confirmed. Delivery then takes 3 to 5 business days in the UAE or 7 to 10 business days elsewhere, tracked and insured by DHL. That means allowing about five weeks if you're in the UAE and six weeks for international delivery. Import duties abroad depend on your country.
You can add engraving when you order and a handwritten note at checkout. The ring arrives in our signature packaging with its Authenticator, and the 5-year warranty covers verified manufacturing defects.
At YAZ & Co, between AED 4,530 and AED 12,520. The Lumière and Harmony at their smallest carat weight are the least expensive, and the Majesté Tennis Ring is the most. On centre-stone rings, the price follows the carat weight and shape you choose. Eternity bands each have one fixed price, from AED 7,670 to AED 12,520. Gold colour and ring size don't affect the price.
Whatever looks right on your hand and suits how you live. As a rough guide, 1 carat looks refined and is easy to wear every day, 2 carats gets noticed straight away, and 3 to 4 carats is a statement. For context, The Knot's 2025 Real Weddings Study found that lab-grown centre stones averaged 2.0 carats, compared with 1.6 carats for mined diamonds. Shape changes the picture too, so try a few on before you decide.
Yes. It's crystallised carbon with the same structure, hardness and fire as a mined diamond. The only difference is that it grew in a lab rather than underground. The US Federal Trade Commission stopped using "natural" in its definition of a diamond when it revised its Jewelry Guides in 2018, and The Knot's 2025 Real Weddings Study found that more than half of engagement rings now feature a lab-grown stone. Our lab-grown vs natural diamonds guide compares the two, and Lab-Grown Education explains how they're grown.
Treat it as a ring to wear, not an asset. There's little resale demand for lab-grown stones so far, so expect to get back well under what you paid if you sell. The benefit comes at the start instead: the same budget buys a noticeably larger, higher-graded centre stone than it would in a mined diamond.
Yes. Diamond scores 10 on the Mohs scale, the top of the hardness range, so the stone itself copes well with daily life. The weak point on any ring is the setting, so take it off for the gym, heavy lifting and cleaning with chemicals, and have the setting checked now and then. Hand cream and soap leave a film that dulls the sparkle, which our free cleaning and inspection service takes care of.
Photos can't show you how a 2-carat oval compares with a 2-carat round on your own hand. At our Abu Dhabi boutique you can try sample rings side by side, compare gold colours in daylight and get your finger sized properly. Book a private appointment, or if you're overseas, our concierge team can help over WhatsApp or a video consultation. Planning the whole day? See our bridal jewellery, and pair your ring with lab-grown diamond earrings or a tennis bracelet.
