Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a delicate shimmer that seems to dance with every movement. This semi-set halo engagement ring in 18K rose gold frames a 6 x 3.5 mm marquise stone, its pointed ends lending a graceful, almost poetic tension to the design.

Crafted with a low-profile halo setting, the ring balances intricate detail with everyday wearability. The warm blush of rose gold complements the diamond’s crisp facets, while the halo’s fine pavé work enhances brilliance without overwhelming the hand. Each curve is hand-finished in our Williamsburg studio, ensuring a smooth comfort fit that slips easily beneath gloves or stacks seamlessly with other bands.

Our diamonds are lab-grown, offering a clarity and sparkle equal to mined stones but with a lighter environmental footprint. This ring’s ethical foundation is quietly woven into its beauty.

Ideal for someone drawn to romantic shapes with a modern edge, the marquise elongates the finger and lends a subtle drama without excess height. Its semi-set nature invites you to select a center stone that speaks personally, making the design uniquely yours.
