Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated facets of a marquise diamond, casting a slender, dramatic silhouette that draws the eye along the length of the finger. This semi-set three-stone engagement ring foundation in warm 14K yellow gold invites your choice of a 12 x 6 mm center stone, framed by two delicately crafted side settings that balance presence with subtlety.

Each band is hand-shaped in our Williamsburg studio, finished with a smooth comfort fit that rests lightly for daily wear. The low-profile mounting ensures the ring slips easily beneath gloves or stacks gracefully with other bands, while the artisan polishing reveals the soft glow of yellow gold’s natural warmth.

Our commitment to sustainability shines through the lab-grown diamond option, offering clarity and brilliance without compromise. This ethical choice aligns with a modern approach to fine jewelry, mindful of origin and impact.

Designed for those who appreciate architectural elegance and refined craftsmanship, this marquise semi-set suits hands that welcome a statement piece with a slender, elongating effect. The three-stone style adds dimension without overwhelming, ideal for layering or standing alone.
