Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along a graceful, confident line. This semi-set engagement ring foundation in warm 18K rose gold offers a modern-minimal frame, designed to highlight a 6 x 3.5 mm marquise center stone of your choosing.

Crafted with precision in Williamsburg, the band’s sleek profile balances structure with subtle elegance. Accents along the shank add refined clarity without distraction, while the low-profile setting ensures everyday comfort and ease beneath gloves or rings stacked alongside.

Each piece reflects a commitment to ethical jewelry through lab-grown diamonds, combining sustainability with exceptional clarity and brilliance. The rose gold’s gentle blush complements the marquise’s dramatic shape, ideal for those who appreciate architectural lines softened by warm metal tones.

This mounting suits wearers seeking a distinctive yet wearable ring—its slender band and secure prongs accommodate a range of hand sizes and styles. Resizing is available to ensure a precise fit, with care instructions provided to maintain the finish’s subtle glow.
