Lab-Grown Diamond Engagement Ring

Imagine the subtle elongation of your finger framed by a 12 x 6 mm marquise diamond, its tapered points softened by a delicate halo that catches light from every angle. This semi-set engagement ring foundation in 10K yellow gold offers a low-profile silhouette designed for everyday grace without compromising presence.

Crafted with precision in Williamsburg, the band’s smooth finish and secure halo setting ensure comfort and durability, making it an ideal choice for those who favor a refined yet practical design. The semi-set style invites you to select a center stone that resonates personally, allowing for a truly bespoke expression.

Each piece features a lab-grown diamond option, reflecting a commitment to ethical sourcing and environmental mindfulness without sacrificing brilliance or clarity.

Its slender band and modest height make this ring glove-friendly and stackable, suited for hands that appreciate subtle sophistication alongside active lifestyles.
