Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, dramatic shadow that seems to dance with every movement. This semi-set three-stone engagement ring foundation in cool platinum invites your choice of center stone, designed to frame and elevate a 10 x 5 mm marquise with architectural grace.

Handcrafted in our Williamsburg studio, the ring features a low-profile setting that balances presence with everyday comfort. The platinum band is meticulously finished to a smooth, satiny touch, ensuring it sits comfortably against the skin while offering durability for daily wear. Each prong is carefully shaped to secure the stone while allowing light to flood the facets, enhancing brilliance without bulk.

Our commitment to ethical jewelry is reflected in the exclusive use of lab-grown diamonds, combining clarity and sustainability in one refined design.

Ideal for those who appreciate a statement piece that remains understated in its wearability, this mounting suits slender to medium finger sizes and pairs beautifully with stackable bands or a wedding ring of similar profile. Its streamlined silhouette slips easily beneath gloves or sleeves, making it a versatile choice for modern life.
