Lab-Grown Diamond Engagement Ring

Imagine the gentle curve of a marquise diamond catching the soft morning light, its elongated silhouette casting a delicate shadow across your hand. This semi-set engagement ring invites you to select a 6 x 3.5 mm marquise stone, known for its graceful taper and subtle drama, evoking quiet confidence and refined elegance.

Crafted from warm 14K rose gold, the slender band is polished to a satin finish that feels smooth against the skin, designed with a low-profile setting to sit comfortably beneath gloves or alongside other rings. The solitaire style emphasizes the stone’s unique shape, held securely by delicate prongs that allow light to dance freely through every facet.

Each piece is meticulously finished in our Williamsburg studio, where expert hands inspect every detail to ensure a seamless balance of form and function. The rose gold’s gentle blush complements the marquise’s vintage-inspired charm, creating a ring meant for daily wear and quiet moments alike.

Our commitment to ethical jewelry is reflected in the lab-grown diamond option, offering clarity and brilliance with a smaller environmental footprint. This ring suits those who appreciate subtle romance and modern craftsmanship, especially if you prefer a slender profile that layers effortlessly with wedding bands or stackable designs.
