Frequently Asked Questions

Everything you need to know about lab-grown diamonds, IGI certification, gold, shipping, and buying from Inasha Diamonds.

About Lab-Grown Diamonds

Are lab-grown diamonds real diamonds?

Yes. Lab-grown diamonds are 100% real diamonds — chemically, physically, and optically identical to mined diamonds. They are composed of pure carbon in a cubic crystal structure, score 10 on the Mohs hardness scale, and cannot be distinguished from mined diamonds by standard diamond testers. The only difference is origin: lab-grown diamonds are created in controlled scientific facilities over weeks rather than underground over millions of years.

How much cheaper are lab-grown diamonds compared to natural diamonds?

Lab-grown diamonds are typically 50–70% less expensive than mined diamonds of identical cut, colour, clarity, and carat weight. A 1.0 Ct IGI-certified round brilliant lab-grown diamond that might cost ₹3,00,000 as a mined stone is available as a lab-grown diamond for approximately ₹85,000–₹1,20,000. The price difference is due to a shorter, more efficient supply chain — not any difference in the diamond itself.

Are lab-grown diamonds a good investment?

Lab-grown diamonds are best viewed as luxury goods rather than financial investments — their retail value has declined significantly since 2020 as production scaled. However, the jewellery itself — the craftsmanship, the gold or platinum setting, the design — retains value. Buyers who prioritise owning a larger, more brilliant certified diamond within their budget will find lab-grown diamonds exceptional value.

What diamond shapes does Inasha Diamonds offer?

Inasha Diamonds offers lab-grown diamonds in all major shapes: Round Brilliant, Oval, Pear, Marquise, Emerald, Cushion, Radiant, Asscher, Princess, and Heart. For engagement rings, round brilliant and oval cuts are our most popular choices. For pendants and earrings, round, marquise, and pear cuts are particularly sought after.

Certification & Quality

What does IGI certified mean?

IGI (International Gemological Institute) is the world's largest independent gemological laboratory. An IGI certificate confirms a diamond's exact 4Cs — Cut, Colour, Clarity, and Carat weight — as assessed by independent gemologists. The report number is laser-inscribed on the diamond's girdle and can be verified online at report.igi.org. Every diamond sold by Inasha Diamonds carries an IGI certificate.

How do I verify my IGI diamond certificate?

Visit report.igi.org and enter the report number printed on your IGI certificate. The IGI database will display your diamond's exact 4Cs specifications within seconds — free of charge, from anywhere in the world. Your diamond also has this report number laser-inscribed on its girdle, which can be verified under magnification.

What is BIS Hallmark gold?

BIS Hallmark is India's official gold purity certification, issued by the Bureau of Indian Standards. A BIS Hallmark guarantees the stated purity of the gold (9K, 14K, or 18K) and includes a unique HUID number verifiable at bis.gov.in. Under Indian law, all gold jewellery sold in India must carry a BIS Hallmark. Every Inasha Diamonds piece is set in BIS Hallmark certified gold or 950 platinum.

What is the difference between 9K, 14K, and 18K gold?

The K (karat) indicates gold purity. 18K gold is 75% pure gold — the standard for fine diamond jewellery in India and the UK, offering the richest colour and highest intrinsic value. 14K gold is 58.5% pure — more durable and more affordable, the most popular choice in the USA. 9K gold is 37.5% pure — the most affordable and durable option, ideal for everyday jewellery. Inasha Diamonds offers jewellery in all three gold types plus 950 platinum.

Can I get a diamond ring custom made?
