Lab-Grown Diamond Engagement Ring

When light catches the elongated points of a marquise diamond, it creates a striking silhouette that subtly elongates the finger. This semi-set engagement ring in platinum awaits your choice of an 8 x 4 mm marquise center, designed to showcase the stone’s tapered drama with precision.

Crafted in platinum for enduring strength, the mounting features a low-profile setting that sits close to the hand, minimizing snagging and enhancing comfort for everyday wear. The clean lines and secure prong work ensure the diamond is held with technical assurance, while the band’s smooth finish complements stacking or solo wear.

Each piece reflects our commitment to ethical jewelry, featuring lab-grown diamonds that offer clarity and brilliance without compromise. The semi-set design allows you to select a marquise stone that fits your vision, supported by a setting engineered for balance and durability.

Ideal for those who appreciate refined geometry and a sleek silhouette, this ring suits slender to medium finger shapes, offering a comfortable fit that transitions seamlessly from daily life to special moments. Its low profile makes it glove-friendly and unobtrusive.

Should resizing be needed, our Brooklyn studio handles adjustments with care to maintain the ring’s integrity and finish. Typical lead times accommodate custom stone selection and setting.
