Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it carves a striking beam across the hand—an elegant statement of refined geometry and quiet confidence. This semi-set platinum mounting awaits your choice of a 12 x 6 mm marquise center, designed to showcase the stone’s tapered drama with a modern-minimal frame.

Crafted in platinum for enduring strength and a cool, luminous finish, the setting features delicate accent stones that enhance the center’s brilliance without distraction. The low-profile design ensures comfortable daily wear, while the secure prong arrangement balances protection with maximum light exposure.

Each piece is meticulously finished and inspected in our Williamsburg studio, reflecting a commitment to precision and subtle sophistication. The lab-grown diamond option offers a clear, sustainable choice—ethical jewelry that honors both beauty and responsibility.

Ideal for those who appreciate architectural clarity and a confident silhouette, this mounting pairs effortlessly with stacking bands or stands alone as a statement of modern romance. Its streamlined shape fits comfortably beneath gloves and complements a variety of hand sizes.
