“Is it a real diamond?” It’s the first question we hear in our Mangaluru showroom, and it deserves a straight answer: yes. A lab-grown diamond is a real diamond — not a substitute like cubic zirconia or moissanite. Here’s what’s the same, what’s different, and how to decide.
What’s exactly the same
Chemistry and structure. Both are pure carbon in the same crystal structure. A lab-grown diamond isn’t “like” a diamond; it is one.
Hardness and durability. Both measure 10 on the Mohs scale — the hardest natural material known. Your ring will outlast you either way.
Sparkle. Same refractive index, same fire, same brilliance. Even a trained gemologist cannot tell them apart by eye; it takes specialised lab equipment.
Grading. Both are graded by the same laboratories (IGI, SGL, GIA) on the same 4C scale. An E-colour VS1 lab-grown diamond meets the identical standard as an E-colour VS1 mined one.
What’s actually different
Origin. Mined diamonds formed underground over a billion or more years. Lab-grown diamonds are crystallised over several weeks in a controlled facility, using the same conditions of extreme pressure and temperature (or a carbon-vapour process). Different birthplace, same stone.
Price. Because supply isn’t constrained by mining, lab-grown diamonds cost far less — commonly 60–70% less for the same size and grade.
Footprint. No mining means no displaced earth and none of the sourcing concerns that have followed the mined-diamond trade. Every one of our stones is grown and certified, with a paper trail.
Resale mythology. You’ll hear that mined diamonds “hold value.” In practice, jewellers buy back mined diamonds well below retail too. What protects you is a written buy-back policy — ours is 80% exchange on diamond value and 60% buy-back on invoice, in writing, for lab-grown pieces.
How to tell them apart
You can’t — and neither can we, by eye. Certified lab-grown diamonds carry a microscopic laser inscription on the girdle with the certificate number, so there’s never confusion about what you own. That inscription plus the IGI/SGL certificate is your guarantee.
Which should you choose?
If the romance of a billion-year-old stone matters to you and budget is no constraint, mined diamonds are beautiful things. If you want the identical sparkle, a certificate from the same lab, and a much saner bill — lab-grown is simply the smarter buy. Come compare both side by side at our showroom in Mangaluru, open daily 11 AM – 7 PM, and decide with your own eyes.
