Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, dramatic sparkle that dances with every movement. This 9 x 4.5 mm marquise center stone is nestled securely in a 14K white gold setting, where delicate accent stones trace the band’s gentle curve, adding subtle shimmer without overwhelming the diamond’s distinctive shape.

Handcrafted in our Williamsburg studio, the ring features a low-profile mounting designed for daily wear—its smooth comfort fit ensures it rests naturally on the finger. Each facet is meticulously polished, and the prongs are shaped to protect the pointed ends of the marquise, balancing elegance with durability.

Our commitment to sustainability shines through the lab-grown diamond’s clarity and brilliance, offering an ethical alternative without compromise. This ring’s refined silhouette suits those who appreciate architectural grace paired with artisanal detail, ideal for stacking or wearing solo with understated confidence.

Should you need adjustments, resizing is handled in-house with care to maintain the ring’s integrity and finish. Typical lead times reflect our dedication to precision and quality.
