The distinctive marquise outline creates an eye-catching focal line along the finger, while the six-prong basket setting provides structural confidence. Wearers appreciate how the open gallery keeps the design feeling light and balanced for everyday wear.

Crafted to highlight geometric symmetry, this three-stone design puts a marquise lab-grown diamond at the focal point. The central gem is supported by a three-stone basket structure and anchored with six dedicated prongs, ensuring balanced hold and structural integrity. Because the gallery remains open, light enters the lab-grown diamond from multiple angles, maximizing its shape definition. The ring transitions smoothly into standard shoulders that blend directly into an uniform, round shank. A high-polish finish covers the band, creating a smooth tactile feel against the finger. Available in platinum, silver, and yellow, rose, or white gold, this piece offers a clean profile that layers comfortably alongside other bands or stands comfortably on its own.
