Lab-Grown Diamond Jewellery

Showing 27 of 296 products

Lab grown diamond jewellery is the same carbon, the same hardness and the same brilliance as a mined diamond, at roughly a quarter of the price per carat. Every centre stone above 0.30 ct carries its own IGI report and every gold or platinum mount is BIS hallmarked, so the stone and the metal are both independently documented. Compare a lab-grown stone with a natural one at our Sector 45, Gurugram showroom, or learn how to read an IGI report before you order.

Lab-grown diamond jewellery buying guide

Lab-grown diamonds are real diamonds, chemically and optically identical to mined stones, grown in a controlled environment instead of the earth. GemHub sets IGI-certified lab-grown diamonds in BIS-hallmarked gold and 950 platinum, made in our own Gurugram workshop and sold direct.

Why buyers choose lab-grown

  • Value. The same carat, colour and clarity costs a fraction of a natural diamond, so a 2 to 3 carat solitaire or a full tennis bracelet becomes realistic.
  • Certification. Every centre stone above 0.30 ct carries an IGI report with a laser-inscribed number you can verify online.
  • Traceability. Lab-grown diamonds carry no mining footprint and a documented origin.

The 4Cs, briefly

Carat is weight; cut controls sparkle (ask for Excellent or Very Good on rounds); colour D to F is colourless and G to H is near-colourless and better value; clarity of VS or VVS is clean to the eye. Our stock is typically E to F colour and VS to VVS clarity.

CVD or HPHT?

Both growth methods produce genuine diamonds and both are graded by IGI on the same scale. What matters is the grade on the certificate, not the growth method.

Frequently asked questions

Are lab-grown diamonds real diamonds?

Yes. Lab-grown diamonds have the same chemical composition, crystal structure, hardness (Mohs 10) and brilliance as mined diamonds. They are graded on the same 4Cs by laboratories such as IGI.

How do I verify a GemHub IGI certificate?

The IGI report number is printed on your invoice and, on most stones, laser-inscribed on the diamond's girdle. Enter the number on the IGI website's report verification page to see the full grading report.

Why are lab-grown diamonds cheaper than natural diamonds?

Growing diamonds in a laboratory is faster and more scalable than mining, and there are fewer middlemen. GemHub manufactures in-house, which removes distributor margins as well.

Do lab-grown diamonds hold up to everyday wear?

Yes. They are as hard and durable as mined diamonds and are the standard choice for engagement rings, studs and tennis bracelets worn daily.

Can I customise lab-grown diamond jewellery?

Yes. Choose the carat, shape, colour and clarity and the metal, approve a free CAD render, and we craft the piece in 7 to 15 working days.
