2 Carat Lab Grown Diamond Price in India: Buyer’s Guide 2026

If you are searching for the price of a 2 carat lab-grown diamond in India, it means you are already serious about making a purchase. We understand that a 2-carat diamond is not a small purchase for you. However, it is significant, noticeable, and expensive enough that you cannot afford to make mistakes or rely on incomplete information. And most importantly, most online pages confuse you more than they help.

You might already know about 1 carat lab grown diamond price in India, but once you move to 2 carat, things change fast. The price jump is not linear. For example, small differences in cut, colour, clarity, and certification can change the final amount by lakhs. That is why many customers get stuck at this stage. In India, lab-grown diamond prices also depend on where you buy from, which certificate you choose, and how transparent the brand is.

In this guide, you will understand the 2 carat lab diamond cost, how pricing works in 2026, what SGL-certified 2-carat lab diamond India really means, and how brands like Lukson lab-grown diamonds price their jewellery honestly. If you plan to buy lab diamonds online, this guide is meant for you.

What is a lab-grown diamond? 

A lab-grown diamond is a real diamond, just made in a lab instead of coming out of the ground. The carbon structure is the same. The hardness is the same. Even the sparkle is the same. The only difference is where it is created.

In simple words, you are buying a diamond, but not a diamond that comes from the earth. That is why lab-grown diamonds are graded on cut, clarity, colour, and carat, just like mined ones. Many customers choose them today because you get better quality for the price you pay, without dealing with mining issues.

Key Things That Change the Price of Lab Diamonds

1. Cut and Shape

Cut and shape play a very big role in deciding the final price. Round diamonds are always the most expensive because demand is high and wastage during cutting is higher. That is why round brilliant diamonds are treated as the base price. If you choose oval, cushion, pear, or princess cuts, you pay 15–20% less for the same carat weight. Many customers do this intentionally. These shapes still look big and bright, but help you manage the budget better, especially when you are buying a 2-carat lab-grown diamond.

2. Certification

Certification is something you should never ignore. Diamonds certified by IGI or SGL are trusted more because grading stays consistent. This matters when you want peace of mind after buying. Certified diamonds are easier to compare, exchange, or resell in the future. Because of this trust factor, certified diamonds cost slightly more than non-certified ones. But note it, paying a little extra for certification makes sense, especially when you are spending on a high-value stone like a 2-carat lab-grown diamond in India.

3. Manufacturing Method

Lab-grown diamonds are mainly made using two methods: CVD and HPHT. In India, CVD diamonds are preferred, especially for larger sizes like 2 carats. The reason is simple. CVD diamonds have better consistency, good structure, and more even shine. HPHT diamonds are also real diamonds, but for bigger sizes, buyers often notice colour tones or growth marks. That is why most brands and jewellers recommend CVD when you are buying a higher carat lab-grown diamond.

4. Setting Metal

The metal you choose affects the final price more than many people expect. The diamond price is one part, but the ring or setting adds a big amount. For example, a basic solitaire setting in 18K gold can add anywhere between ₹25,000 to ₹50,000. Platinum costs even more. If you choose heavier bands or custom designs, the cost increases further. So while planning your budget, always calculate the diamond cost and metal cost together. 

Smart Buying Tips for Lab-Grown Diamond Price in India

1. The “Under-Weight” Hack

This is a very common trick smart buyers use, and in fact, it makes a lot of sense. Diamonds priced exactly at 2.00 carats jump sharply because of the price-per-carat rule. But here’s the thing: a diamond weighing 1.90 to 1.95 carats looks almost the same to the naked eye. Once it is set in a ring, no one can tell the difference. By choosing slightly under 2 carats, you save a good amount without losing visual size. This is especially useful when buying lab-grown diamonds.

2. Check Buyback and Exchange Policies

Many people ignore this part, but you should not. Buyback and exchange policies tell you how confident a brand is about its jewellery. Some modern lab-grown diamond brands offer up to 80% cash buyback or even 100% exchange value. Traditional jewellery stores usually offer much less, sometimes only the gold value. When you are buying a high-value diamond, this is very important. It gives you flexibility later, whether you want to upgrade, exchange, or simply feel secure about your purchase.

3. Compare Prices from Major Diamond Hubs

Diamond pricing is not the same everywhere. Cities like Surat and Mumbai are major manufacturing and sourcing hubs for lab-grown diamonds in India. Brands sourcing directly from these hubs often price their diamonds more competitively. This does not mean quality is lower. In fact, many top brands are manufactured there. If a brand clearly mentions sourcing or manufacturing in these hubs, you get better value. This is why you should always compare prices, certificates, and policies together before deciding.

Should You Buy a Lab Grown Diamond or a Natural Diamond?

If you are confused between buying a lab diamond or a natural diamond, you are not alone. So many people ask this question.

1. Natural Diamond:

Natural diamonds have been formed on the Earth for billions of years. And that is why natural diamonds will cost you around 65% to 85% more than lab diamonds. You can buy them as an investment. But you must remember this: natural diamonds come with higher prices, mining concerns, and limited flexibility in budget.

2. Lab-Grown Diamond:

Now, let us turn to lab grown diamonds. These are real diamonds, made of the same carbon, same hardness, same shine. The only difference is where they are created. Because lab-grown diamond jewellery does not need mining, the cost drops a lot. As a result, you can buy affordable diamond jewellery with better size, better clarity, or better design in the same budget.
