Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along the finger with quiet drama. This semi-set halo engagement ring foundation in warm 14K rose gold offers a delicate frame, ready to embrace a 12 x 6 mm marquise center stone of your choosing.

Hand-forged in our Williamsburg studio, the band’s subtle curve and low-profile halo setting balance presence with everyday ease. The rose gold’s gentle blush complements the diamond’s fiery facets, while the secure prong setting ensures durability without bulk. Each piece undergoes meticulous finishing and inspection to meet exacting standards of comfort and craftsmanship.

Crafted with a lab-grown diamond in mind, this ring reflects a commitment to ethical sourcing and sustainability, reducing environmental impact without compromising brilliance.

Its slender band and modest height make it an excellent choice for those who appreciate a refined silhouette that layers effortlessly with wedding bands or stackable rings. The semi-set design invites personalization, allowing you to select a marquise stone that resonates with your story.
