Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along a graceful arc. This three-stone semi-set ring in 14K yellow gold offers a modern-minimal frame, where clarity and structure meet quiet confidence.

Crafted in Williamsburg, the band’s smooth finish and low-profile setting ensure the ring sits comfortably for daily wear. The semi-set design invites your choice of a 10 x 5 mm marquise center stone, flanked by two smaller gems that enhance its architectural elegance. Each piece undergoes meticulous hand inspection to guarantee precision and polish.

Our lab-grown diamonds provide the same optical brilliance as mined stones, with a significantly lighter environmental footprint—an ethical choice that complements the ring’s refined simplicity.

The slender band suits those who appreciate clean lines and a contemporary aesthetic, while its subtle height makes it glove-friendly and stackable with other bands. The marquise shape’s elongation flatters slender fingers and adds a distinctive edge without excess.
