Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it carves a slender beam that seems to stretch beyond the hand, evoking a quiet drama. This three-stone semi-set ring in 18K white gold frames a 12 x 6 mm marquise center with two delicate side stones, each carefully positioned to enhance the central gem’s graceful taper.

Crafted in Williamsburg, the band’s polished finish and low-profile setting ensure a comfortable fit that slips easily beneath gloves or alongside other stackable bands. The prongs are meticulously shaped to cradle the marquise securely while allowing maximum light to animate its facets. Each piece undergoes thorough inspection to meet exacting standards of symmetry and polish.

Our commitment to ethical jewelry is reflected in the lab-grown diamond’s clarity and provenance, offering a sustainable alternative without compromise. The slender shape suits hands that appreciate refined geometry and a touch of vintage-inspired elegance, while the three-stone design adds narrative depth—past, present, and future in luminous form.
