Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, luminous beam that seems to stretch beyond the hand. This three-stone semi-set engagement ring in 18K yellow gold frames a 10 x 5 mm marquise center with two delicate side stones, each facet catching light with quiet brilliance.

Crafted in Williamsburg, the band’s warm gold hue is polished to a soft glow, its gentle curve designed for comfort and daily wear. The semi-set foundation invites your choice of a lab-grown marquise diamond, known for its graceful taper and vintage-inspired drama, balanced by a secure yet low-profile setting that slips easily beneath gloves or alongside stackable bands.

Each piece reflects a commitment to ethical jewelry, with lab-grown diamonds offering clarity and sustainability without compromise. The ring’s slender shank and three-stone layout suit those who appreciate romantic detail and a refined silhouette that elongates the finger.

Resizing is available to ensure a perfect fit, with careful hand finishing that preserves the ring’s delicate proportions. Lead times reflect our bespoke approach, allowing for thoughtful customization in our Brooklyn studio.
