Lab-Grown Diamond Engagement Ring

Imagine the gentle warmth of 18K rose gold embracing a square center stone, its precise edges catching light like a quiet promise. This five-stone semi-set invites you to select a 4.5 x 4.5 mm square diamond, whose geometric clarity offers a modern yet intimate presence on the hand.

Crafted in Williamsburg, Brooklyn, the band’s soft polish and subtle taper ensure a comfortable fit that sits low enough for everyday wear without sacrificing sparkle. The five-stone setting balances architectural formality with delicate romance, each prong meticulously finished to cradle your chosen diamond securely.

Our commitment to sustainability is reflected in the lab-grown diamond option, offering exceptional clarity and brilliance with a lighter environmental footprint. This ring suits those who appreciate clean lines and a refined silhouette, ideal for stacking or wearing solo with ease.

Should you need resizing, our in-studio artisans handle adjustments with care to maintain the ring’s integrity and finish. Typical lead times allow for thoughtful customization without rush.
