Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender beam that dances across the hand. This semi-set three-stone engagement ring invites you to choose a center stone measuring 12 by 6 millimeters, its tapered points lending a graceful drama to the design.

Crafted from warm 18K yellow gold, the band is shaped and polished in our Williamsburg studio to a smooth comfort fit that rests lightly for daily wear. The three-stone setting balances architectural precision with artisan finish—each prong hand-formed to cradle your chosen diamond securely while maintaining a low profile that slips easily beneath gloves or sleeves.

Our commitment to ethical jewelry shines through the option for a lab-grown center diamond, offering clarity and brilliance with a smaller environmental footprint. This ring’s silhouette suits those who appreciate a statement piece that elongates the finger, pairing beautifully with slender stacking bands or worn solo for focused elegance.

Should you need resizing, our in-studio experts ensure a seamless adjustment without compromising the ring’s integrity. Typical lead times reflect the custom nature of the semi-set design, allowing you to select a stone that speaks uniquely to your story.
