Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, luminous shadow that dances with every movement. This semi-set engagement ring invites you to choose a center stone that echoes that graceful, tapered drama.

Crafted from warm 10K rose gold, the band is hand-finished in our Williamsburg studio to a soft, satin touch that feels natural against the skin. Its low-profile solitaire setting balances secure prongs with an open gallery, allowing light to flood the marquise’s facets while maintaining everyday wearability.

Each lab-grown diamond offers a clarity and brilliance that honors sustainable practices without compromise. This ring’s ethical foundation reflects a quiet commitment to responsible luxury.

The slender band suits hands that appreciate subtle elegance, while the marquise shape visually elongates fingers, creating a refined silhouette. Its comfort fit and modest height make it ideal for stacking or daily wear beneath gloves.

Should you wish to adjust the band size, our in-studio artisans provide precise resizing to ensure a seamless fit.
