You've found the perfect diamond ring. The sparkle's right, the design's right, even the price checks out. Then the salesperson hands you a certificate covered in letters that mean nothing to you. IGI. SGL. GIA. And just like that, buying the diamond feels harder than picking it ever did.
Here's the thing: certification for lab-grown diamonds in India matters just as much as the design you fell in love with. It's what tells you the sparkle is real, and that you're paying for exactly what's in the box, nothing more, nothing less.
This lab made diamond authenticity guide breaks down what each certification actually means, and which one you should really be paying attention to.
Understanding diamond certifications
A diamond certificate is an independent report that evaluates a diamond's characteristics, including its cut, colour, clarity, and carat weight. It serves as proof of quality and helps you compare diamonds objectively. Let’s walk you through your lab made diamond authenticity guide before making a purchase
International Gemological Institute (IGI)
IGI is one of the most widely recognised laboratories for grading lab-grown diamonds worldwide. Most leading jewellery brands in India offer these reports, and they tell you exactly what you're paying for, down to the diamond's quality.
For most people purchasing lab grown diamonds jewellery, an IGI certificate is considered a trusted and reliable choice.
Solitaire Gemmological Laboratories (SGL)
SGL is an Indian gemological lab that certifies both natural and lab-grown diamonds. It's well recognised within the domestic market, and you'll often spot it on jewellery sold by Indian retailers.
It can offer some assurance about quality, sure. But it's still worth going through the report yourself, and buying from a reputed brand.
Gemological Institute of America (GIA)
GIA is one of the world's most respected gemological institutions. While it has long been regarded as the benchmark for natural diamond grading, it also grades lab-grown diamonds.
However, in India, GIA-certified lab-grown diamonds are less commonly available than IGI-certified ones, especially for everyday jewellery collections.
Which certification matters most for lab-grown diamonds in India?
IGI certification is usually the safer bet for lab-grown diamonds in India. Retailers recognise it widely, the grading reports are thorough, and it makes comparing diamonds across brands so much easier.
That said, don't let the certificate do all the deciding. A jeweller worth trusting will also be upfront about pricing, walk you through the grading report, and be clear about exchange and after-sales policies.
Rather than asking, "Which certificate is best?" ask, "Can I trust both the certificate and the brand behind it?" The answer to both questions should give you complete confidence before you buy.
At Jewelbox, certified lab-grown diamonds are paired with transparent guidance, allowing customers to compare designs, understand certifications, and choose jewellery with confidence.

Frequently Asked Questions
Which certification is best for lab-grown diamonds in India?
IGI tends to be the go-to certification for lab-grown diamonds in India, mostly because it's so widely accepted and the grading reports don't leave much room for guesswork. SGL and GIA are trusted too, it really just depends on the retailer and the diamond you're looking at.
Are IGI-certified lab-grown diamonds real?
Yes. IGI certifies genuine lab-grown diamonds and evaluates their cut, colour, clarity, and carat weight using recognised grading standards.
Does certification affect the value of a lab-grown diamond?
Not really. Certification doesn't make the diamond worth more. What it does is give you peace of mind, proof that what you're buying matches what you're being told. And when you're comparing a few diamonds side by side, that's exactly what makes the comparison fair.
How can I check if my lab-grown diamond is authentic?
Verify the grading certificate, match the laser inscription (if available), and purchase from a trusted jewellery brand that offers transparent documentation.
Should I buy certified lab-grown diamond jewellery online?
Yes, you can, as long as the retailer checks a few boxes. Here is a detailed blog on it. Click here.
