1 Carat Lab Grown Diamond Price in India: A Complete Cost Guide
If you’re shopping for an engagement ring, everyday diamond jewellery, or a statement solitaire, one of the first questions you’re likely to ask is:
“What is the price of a 1 carat lab grown diamond?”
In India today, the 1 carat lab grown diamond price typically ranges from ₹30,000 to ₹80,000 per carat, depending on the brand, certification, and quality. At Vai Ra, a 1 CT IGI-certified lab diamond in the highest quality (DEF colour, VVS1 clarity) is priced at ₹35,000 per carat — offering exceptional value without compromising on brilliance or standards.
In this guide, we break down lab diamond pricing, compare lab diamonds with moissanite and natural diamonds, and help you make an informed buying decision.
What Affects Lab Diamond Pricing? (The 4Cs)
1. Carat
A 1 carat lab diamond weighs exactly the same as a 1 carat natural diamond. However, unlike natural diamonds, lab diamond prices do not increase sharply with higher carat sizes. This makes lab diamonds especially popular for engagement rings and solitaire jewellery.
2. Colour
High-quality lab diamonds fall in the DEF colour range, meaning they are colourless and visually identical to top-grade natural diamonds.
3. Clarity
Lab diamonds graded VVS1 or VVS2 are exceptionally clean, with inclusions invisible to the naked eye. Vai Ra primarily works with these premium clarity grades.
4. Cut
Cut has the biggest impact on sparkle. A well-cut lab diamond will reflect light better and often look more brilliant than a poorly cut natural diamond — regardless of price.
Why the Lab Diamond Price Range Is Wider Than Natural Diamonds
Natural diamond pricing is influenced by the globally accepted Rapaport Price List, which acts as a benchmark for per-carat pricing.
Lab diamonds, however, do not have a universal pricing reference. There is no equivalent of Rapaport for lab grown diamonds. As a result:
- Each brand sets its own pricing
- Retail markups vary widely
- Brand positioning significantly affects cost
This is why you may see a 1 carat IGI-certified DEF VVS1 lab diamond priced at ₹80,000 at some brands, while Vai Ra offers the same grade and certification at ₹35,000 per carat.
Importantly, the diamond itself is no different — the sparkle, durability, hardness, and optical performance remain identical.
Lab Diamond vs Moissanite Comparison
When choosing between lab diamond rings and moissanite rings, understanding the differences beyond price is essential.
At Vai Ra, lab diamonds average ₹35,000 per carat, while moissanite averages ₹8,000 per carat.
Moissanite is an excellent diamond alternative — it offers high brilliance, durability, and affordability. However, quality varies significantly in the market.
Many local jewellers sell lower-grade, uncertified moissanites at cheaper prices. Vai Ra uses SGL-certified moissanites, ensuring verified quality, consistent sparkle, and long-term performance.
While lab diamonds replicate the exact properties of natural diamonds, moissanite offers a bold, budget-friendly option — making both suitable for different preferences.
Natural Diamonds vs Lab Diamonds: How Pricing Behaves
Natural diamond prices increase exponentially with carat size due to rarity. A 2 carat natural diamond can cost more than double a comparable 1 carat stone.
Lab diamonds behave differently. Since they are grown in controlled environments, price differences between carat sizes remain relatively stable. This allows buyers to choose larger stones without a dramatic jump in cost.
Are Lab Diamonds Worth the Price?
If your priorities are beauty, transparency, and value, lab diamonds are absolutely worth it. They are chemically and visually identical to natural diamonds and ideal for modern engagement rings.
However, jewellery — whether lab grown or natural — should not be treated as a financial investment.
Jewellery as an Investment: What Actually Holds Value
Diamonds typically do not appreciate significantly at resale. If maximising long-term value matters to you:
- Choose designs with higher gold weight
- Keep the stone component proportionally lower
- Focus on timeless craftsmanship
Gold consistently retains value better than gemstones over time.
Hidden Costs to Watch For When Buying Lab Diamonds
- Missing or unclear certification
- Inflated brand markups
- Low cut quality hidden behind carat weight
- Unverified colour and clarity claims
Transparency is key — a higher price does not always mean better quality.

Frequently Asked Questions About Lab Diamond Pricing
What is the price of a 1 carat lab grown diamond in India?
The price of a 1 carat lab grown diamond in India typically ranges from ₹30,000 to ₹80,000 per carat depending on brand, certification, and quality. At Vai Ra, a 1 CT IGI-certified lab diamond in DEF colour and VVS1 clarity is priced at ₹35,000 per carat.
Why is there such a big price difference in lab diamonds?
Unlike natural diamonds, lab diamonds do not follow a universal pricing benchmark like the Rapaport list. Each brand sets its own pricing, which results in a wider price range even for identical quality stones.
Are lab diamonds real diamonds?
Yes. Lab grown diamonds are chemically, physically, and optically identical to natural diamonds. The only difference is their origin — lab diamonds are grown in controlled environments instead of being mined.
Is a lab diamond better than moissanite?
Lab diamonds and moissanites serve different preferences. Lab diamonds are true diamonds and ideal for traditional engagement rings, while moissanite offers higher brilliance at a lower cost. Both are durable and suitable for daily wear.
What is the price of moissanite at Vai Ra?
At Vai Ra, moissanite jewellery averages around ₹8,000 per carat. All moissanites used are SGL-certified, ensuring superior quality compared to uncertified stones often sold at lower prices.
Do lab diamond prices increase with carat size?
Unlike natural diamonds, lab diamond prices do not increase exponentially with higher carat sizes. This makes larger lab diamond engagement rings significantly more affordable.
Are lab diamonds a good investment?
Jewellery is best purchased for personal value rather than financial return. If investment value matters, choosing designs with higher gold content and lower stone value helps retain long-term worth.
Which certification should I look for when buying a lab diamond?
Always choose IGI-certified lab diamonds or SGL-certified moissanites. Certification ensures verified colour, clarity, cut, and authenticity.
Can I use lab diamonds for engagement rings?
Absolutely. Lab diamonds are one of the most popular choices for engagement rings today due to their beauty, ethical sourcing, and excellent value.
