Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it traces a subtle arc of brilliance that seems to stretch beyond the hand. This semi-set solitaire invites you to choose a 5 x 3 mm marquise center stone, its tapered points lending a quiet drama to the design.

Crafted in 18K white gold, the mounting balances delicate elegance with everyday wearability. The slender prongs cradle the stone securely while maintaining a low profile that slips comfortably beneath gloves or alongside stackable bands. Each ring is meticulously finished by hand in our Williamsburg studio, ensuring smooth edges and a comfort fit that feels as natural as a second skin.

Our diamonds are lab-grown, offering clarity and sparkle with a lighter environmental footprint—an ethical choice made without compromise. The solitaire’s refined silhouette suits those who appreciate modern romance with a hint of architectural grace, especially flattering on slender fingers or as a distinctive accent in a curated stack.

Should you need a custom size, resizing is available with care to preserve the ring’s integrity and finish. Lead times reflect our commitment to thoughtful craftsmanship rather than rush.
