Home / Lab Grown Diamond / Rings

A lab grown diamond ring uses a real, laboratory grown diamond in a gold or platinum setting. The three things that decide how it looks and what it costs are the centre stone (shape, carat and cut), the metal (9KT, 14KT, 18KT gold or platinum) and the setting style (solitaire, halo, three stone, side stone or band). For an engagement ring, most buyers in India start with a solitaire between 0.5 and 1.5 carat, and for daily wear they choose a slimmer design in 14KT or 18KT gold. At Lucira, solitaire rings with a centre stone above 1 carat were listed from about ₹55,000 in October 2026.

Rings are the most searched lab-grown diamond product in India, and also the one where small decisions change the result the most. This guide takes you through ring types, diamond shapes, carat sizes, metals, settings, sizing, and price, with links to the matching collections so you can see real designs at each step. If you are new to lab-grown diamonds in general, the lab-grown diamond guide explains how they are made, how they compare with natural diamonds, and how to read a certificate.

Types of lab-grown diamond rings

Most ring designs come from a small set of styles. Knowing them makes browsing faster, because you can ignore what does not suit your hand or your routine.

Engagement rings

An engagement ring is the one piece of jewellery most people buy with a deadline and a lot of pressure, so it helps to simplify the decision. While buying an engagement ring, choose the shape first, then the carat range that fits your budget, then the metal. The setting can be settled last.

Lucira keeps a full set of engagement ring collections that you can narrow by style. Start with lab-grown diamond engagement rings and solitaire engagement rings, or go straight to halo, side stone, trilogy or toi et moi styles. There is also a collection for men's engagement rings and one for couples.

Is a lab-grown diamond a good engagement ring?

Yes, and a lot of couples now choose one. You get a real diamond with the same hardness and brilliance as a mined stone, and usually a bigger or better cut stone for your budget. The two things to be clear about are the report, so you know exactly what you are buying, and the exchange terms. Lucira's lifetime exchange and buyback policy and return page set out the conditions that apply.

Choosing a diamond shape

Shape is personal, but it also has practical effects. Round brilliants are cut to return the most light, while step cuts such as emerald show clarity more openly. Elongated shapes tend to look larger for their weight. Our diamond shapes guide covers each one in more detail.

Carat size and what to expect

Carat is weight. On a ring, the visible size depends on the shape and the cut as much as on the number. A fair way to choose is by wear and budget instead of chasing a headline carat figure. These collections are organised by centre stone weight:

• 0.25 to 0.49 carat: delicate, daily wear, a gentle first diamond ring.
• 0.50 to 0.99 carat: the range many first time buyers choose, visible without being heavy.
• 1.00 to 1.49 carat: a clear statement on the hand. See also the 1 carat collection.
• 1.50 to 1.99 carat: noticeably larger, with more room for halo or three stone designs, such as the 1.5 ct princess solitaire ring.
• 2 carat and above: a bold look. See also the 2 carat lab-grown diamond rings.

One practical point: a slightly smaller stone with a better cut often looks brighter and bigger than a heavier stone with a weaker cut. If you are comparing two rings, ask to see both on the hand or on a video call.

Gold or platinum

Lucira rings are available in 9KT, 14KT and 18KT gold on many designs, in yellow, white and rose colours, and platinum is available on selected designs. Karat tells you how much of the alloy is pure gold: 9KT is 37.5 per cent, 14KT is 58.3 per cent and 18KT is 75 per cent. Higher karat gold has a richer colour and costs more. Lower karat alloys are generally harder, which many people prefer for a ring that takes daily knocks.

Gold jewellery in India should carry a BIS hallmark with a HUID where hallmarking applies. Check the marking on the piece you receive.

Settings and everyday wear

A prong setting holds the diamond with small metal claws and lets in the most light. A bezel setting wraps the stone in a thin metal rim, which protects the edges and suits active hands. Neither is wrong, but if you work with your hands, type all day, or play sports, a bezel or a low-profile prong setting will be less likely to catch. If you plan to stack rings or wear a wedding band with your engagement ring, check that the shank and the setting leave room for both. Our ring shank page explains how the band shape affects fit and stacking.

Getting the ring size right

The size options appear on each product page. Use the size guide to measure a ring you already wear or the finger itself. A few things help: measure at the end of the day when fingers are at their largest, avoid measuring when your hands are cold, and allow for a wider band if the design is wide, as wide bands usually fit more snugly than slim ones. If you are buying for someone else, borrow a ring that fits the same finger and check its inner diameter. Eternity bands are harder to resize because the diamonds run around the band, so ask about this before you buy one.

Price guide

The table gives a snapshot of listings in October 2026. Prices depend on gold rates, metal, size and stock, so confirm on the product page.

Choosing the perfect diamond ring is about balancing design, carat weight and budget. Whether you're considering a classic solitaire, an engagement ring or a statement piece, explore Lucira's jewellery on EMI collection to discover payment options that can help you plan your purchase without compromising on your preferred ring design.

Everyday, wedding and couple rings

If the ring is not for an engagement, the choice is mostly about how you will wear it.

• Wedding bands: see the wedding rings collection, with separate pages for women's and men's bands, plus eternity and stackable styles.
• Couple rings: matching or complementary designs in the couple rings and couple bands collections.
• Men's rings: the men's rings collection includes solitaires and bands.
• Custom designs: if you want something that does not exist yet, see the customised jewellery page and the build your own jewellery.

How to choose in five steps

1. Pick the purpose. Engagement, wedding, anniversary or daily wear each point to a different style.
2. Set a budget band. Use the price collections above so you only see rings you would actually buy.
3. Pick a shape. Look at a few on screen, then on a video call or in a store if you can.
4. Choose metal and setting. Think about colour, wear and how you use your hands.
5. Check the details. Report, hallmark, size and the policies before you pay.

For a live look, you can use the video call page or find an experience centre on the store locator. 

Lab grown or natural diamond for a ring?

This is the question behind many searches for "lab grown diamond vs natural diamond ring". The stones are the same material, so the choice is mostly about budget, priorities and how you feel about origin. 

A lab grown stone is usually priced lower than a natural stone of similar size and quality, which means your budget can stretch to a larger centre stone or a better cut, or simply leave room for a more detailed setting. A natural stone appeals to buyers who value its geological origin and its established resale market.

Both are real diamonds, and neither can be told apart by eye. If a ring is a long-term keepsake and you want to pass it on, either stone will last, because both are as hard as diamond gets. If you are buying for daily wear and would rather put the savings into a larger stone, lab-grown makes sense. Whatever you choose, ask for the grading report and compare like with like. Our main guide has the full comparison table.

How can you check that a diamond ring is genuine?

You cannot reliably do it at home. GIA notes that simple diamond testers cannot separate lab grown from natural diamonds, and that foggy breath or scratch tests are no substitute for a laboratory. The practical checks are the grading report, the report number inscribed on the stone's edge where applicable, the metal hallmark on the band and the seller's written policies. Ask to see all of them before you pay, and keep them with the ring.

Frequently asked questions

How much is a lab grown diamond ring in India?

At Lucira, diamond rings were listed from about ₹25,000 for casual designs in October 2026, and from about ₹55,000 for solitaire rings with a centre stone above 1 carat. The final price depends on the stone, the metal and the design, so check the live product page.

What is the price of a 1 carat lab grown diamond ring?

It depends on the cut, the report and the setting. Lucira's 1 carat plus solitaire rings were listed from roughly ₹55,000 at the time of writing. You can compare options in the 1 carat collection.

Are lab grown diamond engagement rings worth it?

For most buyers, yes. The diamond is real and as hard as a natural one, and the price is usually lower for comparable size and quality. Treat it as jewellery to wear and keep, not an investment, and read the exchange policy before you buy.

Which diamond shape looks biggest?

Elongated shapes such as oval, pear and marquise usually look larger than a round diamond of the same weight, because more of the stone is visible from above. Round brilliants tend to be the brightest.

Which gold is best for a diamond ring, 14KT or 18KT?

18KT has a richer colour and more pure gold, while 14KT is generally harder and often more practical for daily wear and lower in price. Both work well. The right choice depends on how you will wear the ring and your budget.

Will a lab grown diamond ring last?

Yes. A lab grown diamond has the same hardness as a natural diamond, so the stone itself is durable. What needs care is the setting, so have the prongs checked occasionally and remove the ring for heavy work. See our care tips.

Can I customise a lab grown diamond ring?

Lucira has a customised jewellery page and a build your jewellery page. Check them for what is currently available and ask the team before you place an order for something made to your design.

How do I find my ring size?

Use the size guide on the website, measure at the end of the day, and allow a little extra for wide bands. If you are unsure, a store visit or video call can help you confirm before you buy.

How can I tell if a diamond ring is real?

Not reliably at home. A grading report from an independent laboratory, a matching inscription on the stone where present, and the BIS hallmark on gold are the dependable checks. Basic testers cannot separate lab grown from natural diamonds.
