The Indian jewellery market is undergoing a quiet revolution. Lab grown diamond engagement rings once considered a niche alternative are now the first choice for a growing number of couples across India. And it's easy to see why: the same brilliance, the same IGI certification, and a price that makes a 1-carat solitaire genuinely accessible.
Whether you're shopping in Mumbai, Bengaluru, Delhi, or ordering online, this guide covers everything you need to know before buying a lab grown diamond engagement ring in India in 2026.
What Is a Lab Grown Diamond?
A lab grown diamond is a real diamond chemically, physically, and optically identical to a mined diamond. It's created in a controlled environment using either High Pressure High Temperature (HPHT) or Chemical Vapour Deposition (CVD) technology, replicating the natural process that takes billions of years underground.
The result? A diamond that a gemologist cannot distinguish from a mined stone without specialised equipment. We've covered this in depth in our post on Lab Grown vs Natural Diamonds worth a read if you're still weighing your options.
Why IGI Certification Matters When Buying in India
When purchasing a lab grown diamond engagement ring in India, always insist on an IGI (International Gemological Institute) certificate. IGI is the world's leading certification body for lab grown diamonds and is widely recognised by jewellers and resellers across India.
Your IGI certificate will grade the diamond on the 4Cs Cut, Colour, Clarity, and Carat and confirm it is lab grown. This protects you from misrepresentation and gives you a verifiable record of exactly what you've purchased. Every ring in the Unii Jewels collection comes with a full IGI certificate.
Most Popular Engagement Ring Styles for Indian Brides
Choosing a ring style is as personal as choosing a partner. Here are the four styles our customers love most:
Solitaire
The timeless classic. A single diamond, centre stage, with nothing to distract from its brilliance. Solitaires are the most popular engagement ring style in India and work beautifully with both traditional and contemporary outfits. Browse our Solitaire Engagement Rings the Haloria Radiant Solitaire and Rylisse Round Solitaire are perennial favourites.
Halo
A centre diamond surrounded by a ring of smaller diamonds, creating a halo effect that dramatically amplifies sparkle. Halo rings look larger than their carat weight suggests ideal if you want maximum visual impact. Explore our Halo Engagement Rings, including the stunning Aravellea Round Halo.
Pavé
Tiny diamonds set closely along the band, creating a continuous shimmer. Pavé settings add glamour without overwhelming the centre stone. See the Solmique Round Pavé in our Pavé Engagement Rings collection.
Bezel
A modern, architectural setting where the diamond is encircled by a thin metal rim. Bezel settings are secure, sleek, and growing rapidly in popularity among contemporary brides. The Mytrisa Radiant Bezel is a standout example. Browse our Bezel Set Engagement Rings.
How to Choose the Right Cut for Your Hand Shape
