Did you know the world’s most valuable pink diamond—dubbed “The Eternal Pink”—can now be recreated in a lab, virtually indistinguishable from the original? Lab grown diamonds are not only real—they're revolutionising luxury. These green diamonds achieve the same exceptional hardness and refractive brilliance as natural diamonds, meeting every benchmark of quality without compromise.
Rated a perfect 10 on the Mohs Scale for hardness, they stand shoulder to shoulder with earth-mined diamonds in both resilience and radiance. But here’s where they truly shine— lab grown diamonds in India are making exquisite diamond jewellery more accessible than ever, without compromising on elegance, ethics, or value. These eco-friendly diamonds don’t cost the Earth (literally), making everyday luxury a smart and conscious choice.
What Are Lab Grown Diamonds?
Lab grown diamonds possess the same chemical composition, optical properties, and physical structure as natural diamonds extracted from the earth. Put them side by side: no human eye, no classic gemmology tool, not even a diamond veteran can spot the difference. The only giveaway? Science, not soil. Grown in state-of-the-art laboratories using advanced technology, these diamonds replicate nature’s process— just much faster.
Instead of waiting billions of years for carbon to crystallise under the Earth’s crust, lab grown diamonds are formed in controlled, high-temperature environments. They exhibit the same brilliance, hardness, and structure—and they’re turning the diamond jewellery market on its head.
The future of luxury is lab grown. And it's only just getting started.
How Lab Grown Diamonds Are Made
The science behind lab grown diamonds centres on two advanced methods: High Pressure High Temperature (HPHT) and Chemical Vapour Deposition (CVD).
-
HPHT: Mimics Earth's natural environment by using extreme heat and pressure to convert carbon into diamonds.
-
CVD: A cleaner, more precise process where carbon-rich gases are ionised in a chamber to crystallise carbon into diamond.

The Secret Behind Their Sparkle
One look at a lab grown diamond, and you’ll be drawn in by the brilliance. Why? Born in precision labs—not unpredictable earth—these diamonds grow flawlessly, often emerging with even greater clarity than their mined counterparts.
Fewer inclusions mean higher purity—resulting in better light reflection and that unmistakable sparkle.
For instance, the Enchanted Kreis Diamond Ring is a brilliant example of how clarity and craftsmanship meet. Featuring a dazzling round-cut centre diamond gracefully embraced by a delicate halo of pavé-set diamonds, it is set in a sleek, minimal band.
If you’ve ever held a lab grown diamond in sunlight, you’ll know—the sparkle is nothing short of breathtaking. That unmatched brilliance comes from being created in a controlled environment, free from many of the impurities and inconsistencies found in mined diamonds.
Since lab grown diamonds form under precisely controlled conditions, they tend to have fewer inclusions and greater purity, especially in the higher-quality Type IIa category. This means more light enters, bounces, and dances—creating a vivid sparkle that’s hard to miss.
If you're after diamond jewellery that makes a lasting impression— lab grown is the smart, striking choice.
They Are Similar To Mined Diamonds
From carat and cut to clarity and brilliance, lab grown diamonds match mined diamonds in every measurable way. They weigh the same, look the same, and are certified by the same respected international gemological laboratories.
And when you choose a lab diamond, you’re not just making a smart investment in luxury—you’re buying with confidence, knowing you’re getting a genuine diamond that’s ethically made, expertly crafted, and built to last a lifetime.
Quality
Lab grown diamonds shine under the same 4Cs microscope as mined gems—cut, colour, clarity, and carat—proving their brilliance is equally real, just more responsibly made.
At Limelight, each piece is meticulously inspected to ensure only premium-quality diamonds make it into your jewellery box.
Lab Grown Diamond Engagement Rings
A diamond is more than a symbol of love— today, it’s a symbol of a smart, stylish choice.
Lab grown diamond engagement rings are quickly rising in popularity among modern couples who want it all— unmatched beauty, ethical origins, and exceptional value.
Just like their natural counterparts, lab grown diamonds come in a stunning variety of styles, cuts, and designs—giving you more freedom to express your unique story.
Here are 5 must-have engagement ring cuts:
-
Round Brilliant
-
Princess
-
Baguette (long and rectangular)
-
Marquise (elliptical shape)
-
Pear
Every cut tells a story—especially in lab grown diamonds. Every Limelight ring starts with a diamond cut to ideal proportions—not just for light performance, but for emotion.
Certifications
When buying a lab grown diamond, certification is essential. Always ensure your jewellery is authenticated by trusted global grading bodies like GIA, SGL or IGI.
At Limelight Diamonds, every piece comes with certified assurance, so you can shop with complete confidence.
Clarity
Limelight’s lab grown diamonds include Type IIa CVD diamonds, which are the purest of the pure. With minimal inclusions or blemishes, these diamonds have clarity levels that surpass most mined diamonds, making every piece effortlessly radiant.
Colours
Like mined diamonds, lab grown ones are graded from D (colourless) to Z (light yellow). Choose from near-colourless to warm, romantic tones, depending on the emotion you want your jewellery to evoke.
Curious about how cut, clarity, colour, and carat affect diamond quality? Here’s a detailed guide to understanding the 4Cs of lab grown diamonds.
Conclusion
Here’s a sparkling truth: lab grown diamonds cost up to 40% less than their mined counterparts, while offering equal—if not superior—brilliance and beauty. So, if you're dreaming of diamond jewellery that feels good, looks unforgettable, and reflects your values, lab grown is the way forward.
