Lab-Grown Diamond Engagement Ring

Imagine the subtle drama of a marquise diamond catching light with every turn of the hand—its elongated shape lending a refined silhouette that feels both bold and graceful. This three-stone semi-set engagement ring in platinum offers a structured, modern-minimalist frame, designed to highlight the center stone’s sharp clarity and confident geometry.

Crafted in platinum for enduring strength and a cool, luminous finish, the mounting balances architectural precision with everyday wearability. The low-profile setting ensures the ring sits comfortably beneath gloves or sleeves, while the three-stone arrangement adds depth without excess bulk. Each piece is meticulously hand-finished in our Williamsburg studio, inspected for flawless symmetry and smooth edges.

Our diamonds are lab-grown, offering a transparent origin and a smaller environmental footprint without compromising brilliance or clarity.

Ideal for those who appreciate clean lines and a statement that’s quietly assured, this ring complements slender to medium finger sizes and pairs well with stackable bands or a simple wedding band. The semi-set design invites you to select a center stone that reflects your personal vision.

Should you need resizing or guidance on stone selection, our Brooklyn studio team is ready to assist with care and expertise.
