Large Cushion-Cut Cubic Zirconia Statement Ring in Two-Tone 18k Gold and Silver

This is a significant contemporary statement ring featuring a large, brilliant cushion-cut clear stone, identified as cubic zirconia. The stone is set within an architectural two-tone mounting that highlights intricate metalwork. The setting appears to be constructed from 18k yellow gold accents over a sterling silver or high-grade white metal base, a style often associated with designers like Judith Ripka or Bali-inspired jewelry. The shoulders of the band are adorned with a detailed relief pattern, including granular beads and organic leaf-like motifs that transition into the structural prongs holding the center stone. The metal exhibits a polished finish on the high surfaces with deliberate oxidation in the recessed areas of the carving to enhance the visual depth of the design. The center stone is multi-faceted, providing intense light refraction, though it shows some minor surface abrasions consistent with use. The band is a wide, tapered shank, providing stability for the substantial head of the ring. No specific maker's marks are visible in the provided image, but the craftsmanship suggests a high-quality fashion or fine-jewelry bridge piece from the late 20th to early 21st century. The overall condition is good, showing minor scratches on the band profile and some dulling of the polish on the under-gallery.
