Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a 12 x 6 mm marquise diamond, its tapered points drawing the eye along the finger with subtle drama. This semi-set halo ring in 10K yellow gold frames the center stone with a delicate circle of smaller diamonds, enhancing brilliance without adding bulk.

Crafted for everyday wear, the low-profile setting keeps the ring close to the hand, reducing snagging while maintaining a confident presence. The warm glow of yellow gold complements the marquise’s vintage-inspired shape, finished with a smooth comfort fit band that feels natural from morning coffee to evening strolls.

Each piece is meticulously inspected in our Williamsburg studio, where precision meets quiet elegance. The lab-grown diamond at its heart offers a clarity and sparkle indistinguishable from mined stones, with a fraction of the environmental impact.

Ideal for those who appreciate architectural lines paired with practical design, this halo setting balances statement with subtlety. Its size and shape suit slender to medium fingers, and the semi-set format invites you to select a center stone that reflects your personal story.

Resizing is available to ensure a perfect fit, and our team is happy to guide you through care recommendations to preserve the ring’s brilliance over time.
