Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender beam that dances across the skin. This three-stone engagement ring in warm 14K rose gold cradles a 9 by 4.5 mm marquise center, its tapered points echoing a quiet elegance that feels both intimate and striking.

Each diamond is meticulously set in a low-profile, three-stone arrangement that balances presence with everyday wearability. The rose gold band is hand-finished in Williamsburg, its subtle blush complementing the diamond’s fiery facets while offering a smooth comfort fit that slips easily beneath gloves or alongside stackable bands.

Crafted with lab-grown diamonds, this ring reflects a commitment to ethical jewelry—minimizing environmental impact without compromising brilliance or clarity.

Ideal for those drawn to refined geometry and romantic symbolism, the marquise shape visually elongates the finger, lending a graceful silhouette that suits slender to medium hand sizes. Its low-profile setting ensures it remains a companion for daily life, not just special moments.

Should you need a custom adjustment, resizing is handled delicately in-studio to preserve the ring’s integrity and finish.
