Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it carves a striking, elegant shadow that feels both bold and refined. This semi-set platinum band awaits your choice of a 12 x 6 mm marquise center, designed to showcase the stone’s tapered drama with architectural precision.

Crafted in platinum for enduring strength and a cool, luminous finish, the mounting features delicate accent settings that frame the center without overpowering it. The low-profile design ensures everyday comfort and ease beneath gloves or stacked rings, while the smooth interior promises a gentle fit on the finger.

Each piece is meticulously hand-finished in our Williamsburg studio, where expert jewelers inspect every facet and prong to balance security with sleek minimalism. The ethical clarity of lab-grown diamonds complements this modern silhouette, offering brilliance with a lighter environmental footprint.

Ideal for those who appreciate structured elegance and a confident statement, this setting pairs beautifully with elongated hands or those seeking a distinctive shape that elongates the finger. Resizing is available to ensure a precise fit, crafted with care to maintain the ring’s clean lines.
