Lab-Grown Diamond Engagement Ring

Sunlight catches the delicate curve of a 3.8 mm round diamond, its facets whispering quiet brilliance against the soft glow of 14K white gold. This semi-set solitaire invites you to choose a center stone that reflects your story, framed by a slender band finished in warm rose gold for a subtle contrast that feels both intimate and modern.

Crafted in Williamsburg, this ring balances refined craftsmanship with everyday wearability. The low-profile setting keeps the diamond close to the hand, while the smooth comfort fit ensures it moves with you, never against. Each band is hand-polished and carefully inspected to meet exacting standards before it leaves the studio.

Our diamonds are lab-grown, offering clarity and sparkle without compromise, aligned with a commitment to sustainability and ethical sourcing.

Designed for those who appreciate understated elegance, this solitaire suits a variety of hand shapes and pairs effortlessly with stacking bands or a wedding ring. Its modest scale and gentle curves make it glove-friendly and ideal for daily wear.

Should you need resizing or prefer a custom adjustment, our Brooklyn studio offers personalized consultations to ensure a perfect fit.
