Lab-Grown Diamond Engagement Ring

Light catches the marquise’s tapered points, casting a delicate silhouette that elongates the finger with quiet drama. This three-stone semi-set in platinum frames a 6 x 3 mm marquise center, its sleek shape evoking a refined balance between bold geometry and graceful movement.

Crafted in Williamsburg, the platinum band is polished to a satiny finish, offering a cool, substantial feel that molds comfortably to the hand. The low-profile setting ensures everyday wearability without sacrificing the ring’s sculptural presence. Each prong is meticulously aligned to cradle your chosen center stone securely, while the side stones add a subtle shimmer that complements without overwhelming.

Our commitment to ethical jewelry shines through the use of lab-grown diamonds, which provide exceptional clarity and brilliance with a smaller environmental footprint.

Designed for those who appreciate a statement that remains understated, this ring suits slender to medium finger shapes and layers effortlessly with other bands. Its streamlined silhouette slips easily beneath gloves or sleeves, making it a versatile choice for daily life.

Should you need resizing, our Brooklyn studio offers expert adjustments to ensure a perfect fit without compromising the ring’s integrity.
