We grow, cut, certify and craft lab-grown diamonds — and we believe each one is more than a stone. It's a promise, a memory, a moment worth keeping.
Welcome to C6 Labgrown Diamonds, where every sparkle holds a story and every shimmer carries a sentiment. We believe in the enchantment of diamonds — not just as adornments, but as whispers of love, beacons of trust and echoes of timeless elegance. Each gem we present is a testament to our dedication to quality and craftsmanship.
Choosing a diamond isn't just a decision; it's a heartfelt exploration of connection and commitment. We understand the weight of that journey, and we're here to make it effortless and joyful. Our team isn't just here to sell — we're here to guide, to share and to listen, whether you're seeking advice, searching for the perfect fit, or simply looking to add a little sparkle to your life.
“You're not just buying jewellery — you're investing in moments, in memories, in magic.”
The C6 promise
Because we control every step, we can promise quality at every step — and pass the savings on to you.
Each diamond begins as a tiny seed, grown layer by layer in our own lab.
Master cutters shape every stone to bring out its fire and brilliance.
Independently graded by IGI and GIA, so every promise is on paper.
Set into fine jewellery by hand in our workshop — or your own design.
Insured shipping to clients across the USA, Hong Kong, India and beyond.
We don't want to be just another jewellery brand. We want to be your companion through life's ups and downs — a world where diamonds aren't just possessions but cherished companions, where every facet reflects a facet of your own story, and beauty runs soul deep.
To sprinkle a bit of magic into every moment and celebrate life's journey with brilliance and beauty. We don't just sell jewellery — we create connections, weaving stories that intertwine with yours.
Every stone is graded and documented. No guesswork, no surprises.
Real diamonds — chemically identical to mined — with a smaller footprint.
Our team is here to listen, advise and help you find the right fit.
Crafted to be worn every day and treasured for a lifetime.
Visit us in New York's Diamond District, Texas, Hong Kong or at our home in Surat — or meet our experts on a video call.
Discover a diamond as unique as your journey — certified, handpicked and crafted with care.
