Complete Guide to Buying Lab Grown Diamonds in India

In recent years, jewellery buyers in India have started asking an important question when choosing diamonds: Should I buy a lab grown diamond? What was once a small niche has now become a mainstream choice. Couples, young professionals, and even traditional families are turning to lab grown diamonds for weddings, engagements, and everyday jewellery.

India is also one of the largest producers of lab grown diamonds, making them widely available across markets such as Surat, Mumbai, Delhi, and Bangalore. This guide will walk you through everything you need to know before buying a lab grown diamond in India.

What are Lab grown diamonds?

Lab grown diamonds are real diamonds that are created in modern laboratories using advanced technology. They are not substitutes or look-alikes like cubic zirconia or moissanite. Instead, they are chemically, physically, and optically identical to mined diamonds. Both are made of pure carbon in a crystal structure, both shine with the same brilliance, and both are equally durable with a hardness of 10 on the Mohs scale.

The only difference is how they are formed. Natural diamonds are created deep within the earth over billions of years, while lab grown diamonds are created in controlled environments within weeks. To the naked eye, both look exactly the same, and even professional gemologists need advanced tools to tell them apart.

How Are Lab Grown Diamonds Made?

Lab grown diamonds start with a small diamond seed placed inside a chamber that replicates the conditions deep within the earth. Carbon atoms then build up around the seed until a rough diamond forms. This rough stone is cut and polished the same way as natural diamonds.

There are two methods used to grow diamonds in labs:

CVD (Chemical Vapor Deposition): Carbon-rich gases are heated inside a chamber, and carbon atoms deposit layer by layer onto the diamond seed. This process produces high-quality, clean diamonds.
HPHT (High Pressure High Temperature): A diamond seed is exposed to extreme heat and pressure, mimicking natural conditions. Carbon crystallizes around the seed, creating a rough diamond.

Both processes produce real diamonds, certified and graded on the same standards as mined stones.

How to Check Diamond Certification

A diamond certificate is an independent report that describes the characteristics of your diamond. It is issued by trusted gemological laboratories and serves as proof of authenticity. When buying a lab grown diamond in India, checking the certificate is just as important as choosing the stone itself.

Key points to understand about certification:

4Cs Grading: The certificate includes details of the diamond’s Cut, Color, Clarity, and Carat.
Identification Number: Every certified diamond has a unique number that is often laser-inscribed on the stone for easy verification.
Origin: Certificates for lab grown diamonds clearly mention that the diamond is lab created.
Proportions and Measurements: The report lists the exact dimensions of the diamond, which influence its brilliance.
Security: Certificates are tamper-proof and cannot be duplicated.

Trusted Certification Bodies:

IGI (International Gemological Institute): Widely recognized in India, especially for lab grown diamonds.
GIA (Gemological Institute of America): Global leader in diamond certification, trusted worldwide.
SGL (Solitaire Gemological Laboratories): Also provides certification in India.

Buying Tip: Always ask for the certificate and verify the identification number on the diamond against the certificate. A certified diamond ensures you are getting what you paid for and protects you from misleading claim

Diamond Shapes and Types – How to Choose

When buying lab grown diamonds, shape is one of the most important decisions. Each shape creates a different look on the finger or in jewellery, so understanding how they appear in real designs will help you choose confidently.

Round BrilliantThe most popular shape, known for its Brilliance. Round diamonds look beautiful in solitaires, halos, and pavé rings. They suit all hand shapes and are perfect for someone who wants a timeless, classic look.

Princess CutSquare in shape with sharp edges, the princess cut gives a modern look. It works well in engagement rings, especially when set with side stones or halos. It appeals to buyers who want something elegant but with a contemporary touch.
Emerald Cut
With its rectangular shape and step-cut facets, emerald cuts have a mirror-like shine instead of a fiery sparkle. Emerald cuts are perfect for vintage-inspired or Art-deco style jewellery.
Oval Cut
Oval diamonds make the fingers look slender and longer. They are often chosen for solitaire rings and pair beautifully with pavé bands. A good choice for someone who wants brilliance with a slightly unique shape.
Cushion Cut
A soft square with rounded corners, cushion cuts have a romantic charm. They look stunning in halo rings or antique-style settings. Cushion cuts are ideal for buyers who prefer a softer sparkle with a classic yet unique feel.
Pear Cut
Shaped like a teardrop, pear diamonds combine the brilliance of round with the elongation of marquise. They are often set in solitaire rings pointing upward, which elongates the finger. Pear cuts also look striking in pendants and earrings.
Marquise Cut
Long with pointed ends, marquise diamonds appear larger than they actually are. They create a dramatic, bold look and make the finger look slender. Perfect for statement rings or unique engagement rings.
Baguette Cut
Rectangular with step cuts, baguette diamonds are not usually used as solitaires but shine as side stones or in eternity bands. They give jewellery a sleek, modern, and structured appearance. Great for customers who love geometric, minimalist styles.
