A 0.75ct round lab grown diamond solitaire, set high in a solid 14K/18K gold mount so the stone catches light from every angle — this ring is built for the moments that call for one perfect stone and nothing more. It is the classic engagement silhouette, reimagined with a certified lab grown diamond that gives you significantly more carat weight for the price of a mined stone of the same size.
What makes this piece special is the honesty of a true solitaire — one 0.75ct round brilliant-cut lab grown diamond, IGI certified, held in a secure prong setting that maximizes light return and keeps the stone as the sole focus. The round brilliant cut is the most light-efficient diamond cut in existence, engineered specifically to throw maximum fire and scintillation, which is why it remains the most requested shape for engagement rings worldwide.

This ring is available in 14K or 18K solid gold. 14K offers everyday durability at a lower price point, while 18K carries a higher gold purity and a slightly richer color and weight — both are solid gold throughout, never plated or filled. Alongside the karat choice, it comes in three gold colors: classic Yellow Gold, romantic Rose Gold, and contemporary White Gold, so you can match it to the rest of your jewelry wardrobe or personal preference.
This ring is available in US ring sizes 5.5 to 9. All ring sizes listed are US ring sizes — measure carefully before ordering, or use an existing ring you own and the guide below to find your match.
Clean it with a mild soap, warm water, and a soft-bristle brush, then pat dry with a lint-free cloth to keep the metal and any stones bright. Store it in its own fabric pouch or a lined ring box, away from other jewelry, so it does not scratch or tangle. Take it off before swimming, exercising, or applying perfume, lotion, or hairspray, as these can dull the finish over time, and have the setting professionally inspected once a year to keep every stone secure.
Every diamond in this ring is IGI-certified lab grown — chemically, physically, and optically identical to a mined diamond, at a fraction of the cost, and just as real. Each order ships fully insured worldwide, arrives with certification included, and is backed by GEMHUB & CO.'s 30-day return policy and lifetime exchange program.
Is this a real diamond?
Yes. The 0.75ct total weight of lab grown diamond in this ring is chemically, physically, and optically identical to a mined diamond — it is a real diamond, just grown in a controlled lab rather than mined from the earth.
Can you tell it's lab-grown just by looking at it?
No. Lab grown and mined diamonds are indistinguishable to the naked eye and even under most jeweler's loupes; only specialized gemological equipment can identify the origin, which is noted on the IGI certificate.
Is it certified?
Yes, every diamond is IGI certified, and certification is included with your order as proof of authenticity, carat weight, and quality grading.
What ring size should I order?
