At Coluxe, beauty is only the beginning. Every diamond we create in the lab, and every gemstone we set in gold, carries a story of precision, ethics, and trust. That’s why each Coluxe piece is certified by the International Gemological Institute (IGI) - one of the most respected grading authorities in the world.
Why IGI Certification Matters
Luxury is more than brilliance. It is a certainty.
An IGI certificate validates every detail of your Coluxe stone - its cut, colour, clarity, and carat weight. This independent grading ensures that the lab-grown diamonds you choose carry the same verified quality as mined ones, but with the added assurance of ethical creation.
Lab-Grown, Verified by Science
Our diamonds are born in high-tech laboratories, where science replicates the natural growth process with precision and care. What emerges is a diamond that is chemically, physically, and optically identical to mined - but without the social and environmental costs. IGI certification affirms this truth, putting transparency at the heart of every sparkle.
Our Commitment to Transparency
For us, certification is not a formality - it is a principle. From ethically growing each diamond in state-of-the-art labs to carefully setting it in 14K or 18K gold, we insist on standards that can be measured, tested, and trusted. With IGI’s independent verification, every Coluxe stone carries credentials that match its brilliance.
More Than a Document
An IGI certificate is more than paper. It is proof that the diamond you wear - consciously created and expertly crafted - has been graded to the highest standards. It is a promise of precision, of integrity, and of a new kind of luxury that looks forward, not back.
The Confidence You Deserve
Coluxe is fine jewellery for the self-made - intentional, independent, value-conscious. Our lab-grown diamonds let you own brilliance that is both ethical and extraordinary. With IGI certification, your sparkle is not just stunning to the eye; it is verified, transparent, and rooted in truth. Because confidence in what you own is just as important as the way it makes you feel.
