Lab-Grown Diamond Engagement Ring

Imagine the quiet thrill of a heart-shaped diamond poised to catch the light with every subtle movement of your hand. This semi-set engagement ring foundation in warm 18K yellow gold awaits your choice of a 5 x 5 mm heart-cut stone, its gentle curves promising a tender, symbolic silhouette.

Crafted in our Williamsburg studio, the band is shaped with artisan precision—smooth to the touch and designed for daily wear. The low-profile setting balances presence with comfort, allowing the eventual center stone to sit close to the finger without catching on fabric. Fine accents along the shank hint at delicate craftsmanship, each detail hand-finished and inspected for flawless execution.

Our commitment to sustainability is reflected in the exclusive use of lab-grown diamonds, offering clarity and brilliance with a lighter environmental footprint.

This ring suits those who appreciate romantic symbolism paired with practical elegance—its modest height and comfort fit make it ideal for stacking or wearing solo. The 18K yellow gold complements warm skin tones and invites a lifetime of wear.
