You searched. You scrolled. You asked everyone you know. And still, the doubts linger.
That is fair. Lab-grown diamonds are still a new conversation for many buyers in India, and there is a lot of conflicting information out there. So the House of Quadri team sat down and answered the 25 questions we hear most often, clearly, honestly, and without the fluff.
The Basics: What Are Lab-Grown Diamonds?
1. Are lab-grown diamonds real diamonds?
Yes. Fully, scientifically real. Lab-grown diamonds share the same carbon structure, chemical composition, and physical properties as mined diamonds. They are not simulants. They are not imitations. The only difference is the origin.
2. What exactly are lab-grown diamonds?
Lab-grown diamonds are created in a controlled laboratory environment that replicates the extreme heat and pressure found deep inside the Earth. What nature takes billions of years to do, technology achieves in a matter of weeks, with the same result.
3. Can anyone tell a lab-grown diamond apart from a mined one?
Not with the naked eye. Not even most gemologists have specialised equipment. The two are visually identical. What differs is the journey, not the stone.
4. Are lab-grown diamonds the same as cubic zirconia or moissanite?
No. Cubic zirconia and moissanite are simulants. They look similar but are chemically different materials. Lab-grown diamonds are actual diamonds, not look-alikes.
Quality and Grading
5. How is the quality of a lab-grown diamond measured?
The same way as a mined diamond, through the 4Cs: Cut, Colour, Clarity, and Carat. For a full breakdown of what each C means, our Diamond Education guide is a good place to start.
6. Do lab-grown diamonds have flaws?
They can, just like mined diamonds. Clarity grading applies equally to both. That said, the controlled growth environment often allows lab-grown diamonds to achieve higher clarity grades than their mined counterparts.
7. What is a Type IIa diamond?
Type IIa is the purest form of carbon found in a diamond. Fewer than 2% of mined diamonds are classified as this. The majority of House of Quadri's lab-grown diamonds are Type IIa, which translates to exceptional brightness, transparency, and visual clarity.
8. Do lab-grown diamonds sparkle the same way?
Yes. Sparkle comes from the cut and the carbon structure. Both are identical in a lab-grown diamond. A well-cut lab-grown diamond will outshine a poorly cut mined diamond every time.
Certification and Authenticity
9. Do lab-grown diamonds come with certification?
They should, and at House of Quadri, they always do. Every diamond we sell comes with an IGI (International Gemological Institute) certificate, the most trusted grading body for lab-grown diamonds globally.
10. What does an IGI certificate tell you?
It gives you the exact grade of the diamond across all 4Cs, confirms it is a genuine diamond, and specifies that it is lab-grown. It is your written proof of quality and origin. Never buy a diamond, lab-grown or mined, without one.
11. Why does House of Quadri certify through IGI specifically?
IGI is the global standard for lab-grown diamond grading. Their process is rigorous, internationally recognised, and specifically calibrated for lab-grown stones. When your House of Quadri diamond arrives with an IGI certificate, you know exactly what you own, down to the last detail.
Price, Value, and Budgeting
12. How much more affordable are lab-grown diamonds compared to mined?
Significantly. Lab-grown diamonds are typically 40 to 70% more affordable than mined diamonds of the same grade and size. The supply chain is cleaner and more efficient, which removes many of the traditional cost markups.
13. Does the lower price mean lower quality?
Not at all. The price gap reflects the cost of production, not the quality of the stone. You are getting the same diamond, just without the mining premium attached to it.
14. Do lab-grown diamonds hold their value over time?
Here is an honest answer: Diamonds in general, including mined ones, are not reliable investment assets. Resale value varies. Lab-grown diamonds follow a similar pattern. Buy them because you love them, not as a financial strategy.
15. Can I get a larger diamond for the same budget?
Yes, and this is one of the most practical advantages for Indian buyers. The budget you might spend on a 0.5-carat mined diamond could get you a 1-carat or 1.5-carat lab-grown diamond of equal or better quality.
Ethics and Sustainability
16. Are lab-grown diamonds conflict-free?
Yes. No mining means no conflict. The origin is clean, traceable, and fully transparent. You know exactly where your diamond comes from.
17. Are they better for the environment?
Lab-grown diamonds carry a significantly smaller environmental footprint than mined diamonds. No excavation, no land disruption, no large-scale ecosystem damage. It is a more conscious choice without any compromise on the stone itself.
18. Is the lab-growing process ethical?
Yes. Production takes place in regulated facilities with full accountability. For buyers who care about where their jewellery comes from, lab-grown diamonds offer a clarity that mined diamonds often cannot.
Buying Lab-Grown Diamonds in India
19. Are lab-grown diamonds legal in India?
Completely. India is one of the world's largest producers and processors of lab-grown diamonds. The industry is recognised, regulated, and growing rapidly.
20. Is GST applied to lab-grown diamonds in India?
Yes. Lab-grown diamonds attract GST in India. All House of Quadri pricing is transparent and inclusive of applicable taxes. If you have questions about specific pricing, our team is happy to walk you through it before you decide on anything.
21. Where can I buy certified lab-grown diamonds in India?

Durability and Daily Wear
22. Are lab-grown diamonds durable enough for everyday wear?
Diamonds score a 10 on the Mohs hardness scale, the highest rating possible. Lab-grown diamonds are no different. They are built for everyday wear and will not scratch, cloud, or deteriorate under normal conditions. Read more in our guide on the Mohs hardness scale.
23. How do I care for lab-grown diamond jewellery?
The same way you would care for any fine diamond piece. Clean with mild soap and warm water, use a soft brush, and store separately to avoid surface contact with other jewellery. Avoid harsh chemicals unless your jeweller specifically recommends otherwise. House of Quadri also offers an Annual Complimentary Cleaning Service to keep your piece looking its best.
24. Can lab-grown diamonds be used in engagement rings and bridal jewellery?
Absolutely. Many House of Quadri couples choose exactly that. Lab-grown diamonds are equally suited to solitaires, bridal sets, and everyday fine jewellery. If you are exploring bridal options, our engagement ring collection is a good place to begin.
Making the Right Choice
25. How do I decide between a lab-grown and a mined diamond?
Start with what matters to you personally. If you value a traceable, ethical origin, a better size for your budget, and zero compromise on quality, lab-grown diamonds make a clear case. If you have a deep sentimental preference for a stone formed inside the earth, that is a valid reason too. There is no wrong choice, only an informed one.
