Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along a sleek, architectural line. This semi-set platinum mounting awaits a 6 x 3.5 mm center stone, designed to showcase the marquise’s dramatic shape with modern-minimal clarity.

Crafted in platinum for enduring strength and a cool, luminous finish, the setting features delicate accent details that frame the center stone without distraction. Its low-profile design ensures the ring sits comfortably for daily wear, while the precise setting technique secures the stone with subtle elegance.

Each lab-grown diamond offers a sustainable alternative, reflecting a commitment to ethical jewelry without compromising brilliance or clarity.

The slender band and refined silhouette suit those who appreciate architectural form and confident understatement, pairing effortlessly with stackable bands or worn solo. Its comfort fit and modest height make it glove-friendly and ideal for an active lifestyle.

Should you wish to adjust sizing, our Brooklyn studio offers expert resizing to ensure a perfect fit without altering the ring’s integrity.
