Lab Grown Diamond Price Overview: What Changed in 2026?

How Much Do Lab-Grown Diamonds Cost in India Right Now?

Right now, lab-grown diamond prices in India are much lower than what you saw in 2024 or even early 2025. And this didn’t happen overnight. Production became faster, more factories came in, and buyers also got smarter. Because of all this, lab diamonds today cost around 60–75% less than natural diamonds of the same quality.

On average, lab-grown diamonds are priced anywhere between ₹20,000 and ₹1,50,000 per carat. The exact number depends on cut, colour, clarity, and size. The same quality natural diamond would easily cost you between ₹1.5 lakh and ₹8 lakh per carat. And sometimes even more.

In 2026, prices have more or less settled down. Big drops already happened earlier. Now the market is stable. That said, knowing these numbers helps you spot genuine pricing and avoid paying extra when you buy lab diamonds online or from stores.

1 Carat Lab Grown Diamond Price in India

How Much Does a 1 Carat Lab Grown Diamond Cost in India?

The 1 carat lab grown diamond price in India can vary based on quality factors. Here's a detailed overview of what you should expect to pay.

1 Carat Lab Grown Diamond Pricing Table

Understanding the Price Differences

That price gap you see in 1 carat lab diamonds is not random. The jump from ₹30,000 to ₹80,000 mostly comes down to how clear the diamond is. VVS diamonds are almost spotless, even under magnification. SI diamonds show marks when zoomed in, sometimes even with open eyes. For most people, VS2 clarity with G–H colour hits the sweet spot. You get a clean-looking stone and sensible pricing, usually between ₹30,000 and ₹55,000.

Cut plays a bigger role than people think. A proper, excellent cut can add ₹10,000–₹15,000 per carat. But that extra amount shows clearly in sparkle. A poorly cut diamond looks dull even if everything else is good. This is one area you shouldn’t cheap out on.

Also, keep your eyes open while shopping. If someone is asking ₹1.2 lakh for a VS2, G colour, excellent cut 1 carat lab diamond, that’s straight-up overpricing.

2 Carat Lab Grown Diamond Price in India

How Much Does a 2 Carat Lab-Grown Diamond Cost in India?

A 2 carat lab grown diamond price in India does not always remain in a straight line. It never doubles the 1 carat price. The price keeps fluctuating. Bigger diamonds take more time, more control, more power. Even inside a lab, size is not easy.

1. 2 Carat Pricing Breakdown

If you go for top-level quality like VVS1–VVS2 clarity with D–F colour and an excellent cut, the price will be around ₹1,40,000 and ₹2,00,000. You can choose these types of lab diamonds if the occasion is really big, like milestone anniversaries or heirloom jewellery.

Next comes VS1–VS2 clarity with D–F colour. This range, around ₹1,10,000 to ₹1,50,000, is where many engagement buyers land. For these grades, size is strong and quality is very nice.

The most sensible zone is VS1–VS2 with G–H colour and excellent cut. Prices are around  ₹85,000 and ₹1,25,000. If you set them in gold, no one is going to tell you the difference between G–H from D–F anyway.

If budget is your main concern, SI1–SI2 with G–H colour are going to cost you around ₹65,000 to ₹95,000. You still get the 2 carat presence. And for lab-grown diamond jewellery in India, this range keeps things very easy.

2. Comparing 1 Carat vs 2 Carat Value

A 2-carat diamond costs approximately 2.5 to 3 times more than a 1-carat diamond of similar quality. However, the visual size increase is only about 26% in diameter. This means you're paying significantly more for a moderately larger appearance. For engagement rings where size makes a statement, this premium can be worthwhile. For other jewellery types, multiple smaller diamonds often provide better overall value.

A 2 carat stone costs about 2.5 to 3 times a 1 carat of similar quality. But visually, it only looks around one-fourth bigger. So yes, you pay extra for presence, which is a good thing. For rings, that impact is really important. For other jewellery, smaller stones can be used.

Factors That Affect Lab-Grown Diamond Prices

What Makes Some Lab Grown Diamonds More Expensive Than Others?

1. The 4Cs Impact on Pricing

Cut: Cut is where most of the money goes. A poor cut kills sparkle, even if the diamond is big. An excellent cut throws light properly, and that’s what your eye catches first. That jump alone can push the price up by ₹10,000–₹20,000 per carat, and in fact, you do notice the difference in real life.

Clarity: Clarity changes price based on what you can see, not what a report says. VVS grades cost more because inclusions are hard to spot even under a lens. VS grades are where most people should stop. SI grades are cheaper, but you need to be careful so the marks don’t show once set.

Colour: Colour is also an important part when choosing the lab grown diamond jewellery in India. D–F is fully colourless and priced high. G–H looks the same once the diamond goes into yellow or rose gold, so paying extra rarely adds value.

Carat: Carat weight is another thing that increases the price.  For example, bigger diamonds take more time and control to grow, so price per carat will be on the higher side.

2. Certification and Brand Premiums

Certifications are another thing that impacts prices. There are certifications like IGI, GIA, or SGL. These certifications add a few thousand rupees, but it saves you from overpaying for fake grades.

Brand pricing comes down to trust. For example, you can buy Lukson lab grown diamonds with our premium services. Cheaper sellers may cut costs elsewhere, and that shows later.

3. Metal and Setting Costs

Now comes the metal, which also affects the total bill. A 14K gold setting adds roughly ₹8,000–₹15,000. And 18K goes higher. Platinum jumps even more.

Design also plays an important role in the overall cost. Simple solitaires design will cost less.  Halo and detailed settings push labour up. When you buy lab diamonds online, always check what’s included and what’s not.

The Final Verdict

In 2026, a good 1-carat diamond is going to cost you comparatively less, while a 2-carat diamond will cost you more. That gap itself shows how much you save compared to natural diamonds.
