Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated curves of a marquise diamond, casting a slender, luminous shadow that dances with every turn of the hand. This three-stone engagement ring in 14K white gold frames a 6 x 3.5 mm marquise center with two delicately tapered side stones, creating a quiet narrative of balance and grace.

Each diamond is set low to the finger in a refined prong setting, ensuring a sleek profile that slips comfortably beneath gloves or daily wear. The band’s polished finish and subtle taper enhance the ring’s sculptural flow, while the comfort fit interior invites effortless wear.

Crafted in our Williamsburg studio, this ring features a lab-grown marquise diamond—cultivated with precision to reveal sharp facets and a distinctive, tapered silhouette that elongates the finger. Our sustainable approach reflects a commitment to ethical jewelry without compromise.

Ideal for those who appreciate a blend of classic romance and modern refinement, this piece pairs beautifully with stackable bands or worn solo as a statement of enduring affection. Its low profile and balanced weight make it suitable for active lifestyles and everyday elegance.

Should you need a custom size, resizing is handled expertly in-house to maintain the ring’s integrity and finish. Typical lead times reflect our dedication to meticulous craftsmanship.
