Lab-Grown Diamond Engagement Ring

Sunlight catches the gentle curve of an oval lab-grown diamond, its elongated silhouette casting a soft glow across the hand. This halo setting cradles a 7 x 5 mm center stone in polished platinum, where delicate pavé diamonds trace a luminous frame, amplifying every flicker of light.

Crafted with a low-profile setting, the ring balances elegance with everyday wearability—its comfort fit band smooth beneath the finger, designed to slip easily under gloves or stack alongside other bands. Each facet is meticulously inspected in our Williamsburg studio, ensuring the clarity and brilliance that define our approach to fine jewelry.

Rooted in sustainability, the lab-grown diamond offers a conscious choice without compromising on radiance or integrity.

Ideal for those who appreciate a refined silhouette that elongates the finger, this ring suits hands seeking a blend of subtle drama and timeless grace.

Resizing is available to ensure a perfect fit, with care instructions provided to maintain the platinum’s soft sheen over time.
