Radiant Cut Lab-Grown Diamond Engagement Ring in 14K Solid Rose Gold (IGI Certified)

Half emerald cut, half brilliant — a radiant cut lab grown diamond ring gives you elongated, architectural lines and the sparkle of a round in one stone. Here, a 9 × 6 mm IGI certified lab-grown diamond sits inside a vintage milgrain bezel in solid 10K, 14K, or 18K rose gold, with Art Deco scrollwork tracing the shoulders.

A Radiant Cut That Earns Its Name

The radiant cut was engineered to do two jobs at once: keep the elegant, elongated outline of an emerald cut while packing in the triangular brilliant facets that make round diamonds blaze. The result radiates light from every angle — hence the name — and the elongated proportions of this 9 × 6 mm stone stretch visually along the finger, making the diamond look larger than its footprint suggests.

Trimmed corners also make the radiant one of the most durable diamond shapes for daily wear; there are no sharp points to catch or chip. If you love the geometry, you can compare this piece against our full range of radiant cut engagement rings to see how the shape reads in different settings.

Milgrain Bezel and Art Deco Scrollwork

Rather than perching the diamond on exposed prongs, this design frames it in a full bezel — a continuous rim of rose gold finished with milgrain, the tiny beaded edge detail borrowed from antique jewelry craftsmanship. A bezel is the most secure setting style there is, and the milgrain softens it into something that reads heirloom rather than industrial. You will find the same protective logic across our bezel-set engagement rings.

Along the shoulders, decorative scrollwork adds an unmistakable Art Deco influence. It is the kind of detail usually found on vintage and antique-style engagement rings — a ring that looks inherited on day one.

Solid Rose Gold in Your Choice of Karat

This ring is cast in solid rose gold all the way through — never plated, never gold-filled — so the blush color is permanent and runs through the entire band. Choose your karat from the drop-down:

• 10K — the hardest and most affordable option, best for rough daily wear.
• 14K — the classic balance of durability and gold content, and our most popular choice.
• 18K — the highest gold content, for the richest, warmest rose color.

IGI Certified and Grown Above Ground

A lab-grown diamond is a real diamond — the same carbon crystal, the same Mohs 10 hardness, the same fire — created in a controlled lab instead of pulled from a mine. Curious how that works? Read how lab-grown diamonds are made for the full CVD and HPHT story.

This center stone arrives IGI certified, meaning an independent gemological laboratory has graded and documented the diamond before it reaches you. Certification is your objective, third-party proof of quality — our IGI vs GIA certification guide explains exactly what the report covers. Because the diamond is grown rather than mined, it is fully conflict-free and traceable, at a fraction of the per-carat price of a mined equivalent.

Sizing & Care

Select your ring size and karat from the drop-down menus. If you are unsure of your size, our ring size guide walks you through measuring at home in a few minutes.

Care is refreshingly simple: a diamond is the hardest gemstone on earth, so warm water, a drop of mild dish soap, and a soft brush restore full sparkle in minutes. Dry with a lint-free cloth and store the ring in its box away from other jewelry. For a deeper routine, see our guide on how to care for your engagement ring.
