Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it casts a striking, tapered brilliance that draws the eye along the finger. This semi-set solitaire ring offers a refined foundation for a 9 x 4.5 mm marquise center, designed with a low-profile setting that sits close to the skin for everyday comfort.

Crafted from warm 18K rose gold, the mounting is finished with a smooth polish and precise prongs engineered to secure the stone while maintaining a sleek, unobtrusive profile. The band’s gentle curve and balanced weight ensure it feels natural for daily wear, whether worn solo or paired with complementary bands.

Each piece reflects our commitment to ethical jewelry, featuring a lab-grown diamond option that combines clarity and sustainability without compromise. This ring’s silhouette suits those who appreciate architectural elegance with a modern edge, especially flattering on slender fingers due to its elongating shape.

Resizing is available to ensure a perfect fit, and the semi-set design invites you to select a center stone that resonates personally. Lead times vary slightly depending on customization but are communicated clearly throughout the process.
