Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated marquise diamond, casting a slender beam that dances along the delicate curves of the band. This solitaire semi-set ring frames a 6 x 3 mm marquise stone, its tapered points lending a graceful drama that elongates the finger with quiet confidence.

Crafted in a fixed two-tone combination of warm 18k yellow and 18k yellow and platinum and cool 18k yellow and platinum, the band balances contrast with harmony—18k yellow and platinum prongs secure the stone while the 18k yellow and 18k yellow and platinum shank offers a soft glow against the skin. The low-profile setting ensures everyday comfort, slipping easily beneath gloves or alongside stackable bands without catching.

Each piece is meticulously finished in our Williamsburg studio, where expert hands polish and inspect every facet to reveal the diamond’s clarity and brilliance. The lab-grown origin of the stone reflects a commitment to ethical jewelry, reducing environmental impact without compromising on radiance.

Designed for those who appreciate subtle sophistication, this ring suits slender to medium finger shapes and adapts gracefully to daily wear. Resizing is available to ensure a seamless fit, crafted with care to maintain the integrity of the two-tone design.
