Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of the marquise diamond, its pointed ends drawing the eye along a graceful arc. This semi-set halo ring foundation in 18K yellow gold offers a warm, luminous frame for an 8 x 4 mm center stone, ready to be chosen and set with care in our Williamsburg studio.

Hand-forged by artisans, the band’s smooth polish and delicate halo setting balance durability with refined detail. The low-profile design ensures the ring sits comfortably for daily wear, while the secure prongs cradle the stone to protect its distinctive shape. Each piece undergoes meticulous finishing and inspection to meet exacting standards.

Crafted with a lab-grown diamond in mind, this ring embodies a commitment to ethical jewelry—minimizing environmental impact without compromising brilliance or clarity.

Its slender band and modest height make it ideal for those who appreciate subtle elegance and a ring that layers seamlessly with wedding bands or stackable rings. The marquise shape, with its vintage-inspired drama, elongates the finger for a flattering silhouette.
