The 18K Lab Grown Diamond Round-Cut Halo Ring is built around a dainty halo of round lab-grown diamonds, finished in solid gold and designed for everyday India — from festive gifting to quiet, everyday moments that deserve a little sparkle. Every stone is lab-grown diamond, letting you choose real diamond brilliance at a more accessible price point.
A lab-grown diamond is chemically, physically, and optically identical to a mined diamond — the only difference is that it's grown in a controlled lab environment over weeks instead of being mined from the earth over millions of years. It carries the same hardness, fire, and brilliance as a natural diamond, but typically costs 30-40% less for the same carat weight, which is why lab-grown diamond jewellery has become one of the fastest-growing categories in India. The round cut used here shapes how light travels through the stone, giving this piece its particular sparkle pattern.
A cluster of 17 round lab-grown diamonds is set in a tight halo around the centre stone, creating the look of a single larger diamond while keeping the piece light on the finger. It's the everyday-elegant pick for someone who wants sparkle without a heavy setting.
This design is offered in 18K solid gold. Each karat option is available in Yellow Gold, Rose Gold, and White Gold, so you can match the metal tone to your existing jewellery or personal style — Yellow Gold for a classic, traditional look, Rose Gold for a warmer contemporary finish, and White Gold for a cool, modern edge that lets the diamond take centre stage.
This ring is available in US ring sizes 5.5 to 9. All ring sizes listed are US ring sizes — please check the size chart below before ordering, and reach out to our team if you're unsure which size to pick.
Clean your ring with mild soap, warm water, and a soft-bristled brush to keep the diamond and gold settings free of everyday buildup. Store it in a separate soft pouch or the compartments of your jewellery box so it doesn't tangle with or scratch other pieces. Avoid contact with chlorine, perfume, and lotion, as these can dull the gold's finish over time. We recommend getting the setting professionally checked once a year to make sure prongs and settings stay secure.

Is this a real diamond?
Yes. Lab-grown diamonds are real diamonds — identical in composition and brilliance to mined ones, just grown in a lab. Every piece ships with an IGI certificate confirming authenticity.
Can you tell it's lab-grown just by looking?
No — lab-grown and natural diamonds look identical to the naked eye and even under most jewellers' loupes. Only specialised lab equipment can tell them apart, which is why every GEMHUB diamond ships with an IGI certificate.
What ring size should I order?
