Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, fiery beam across the skin. This three-stone semi-set engagement ring in 18K rose gold frames a 6 x 3 mm marquise center with two delicate side stones, each carefully positioned to enhance its tapered drama.

Handcrafted in our Williamsburg studio, the band’s warm rose gold is shaped with a subtle comfort fit, its smooth interior inviting daily wear. The setting holds the stones securely yet low-profile, designed to slip easily beneath gloves or stack alongside a wedding band without bulk.

Each diamond is lab-grown, offering a clarity and brilliance that honors both the environment and your values. The marquise’s distinctive shape elongates the finger, lending an elegant, architectural grace that suits those drawn to refined, vintage-inspired geometry.

Resizing is available to ensure a precise fit, with careful finishing to maintain the ring’s seamless silhouette. Whether you choose to complete the center stone through our studio or bring your own, this mounting invites personal expression within a crafted framework.
