The marquise cut center diamond is secured in a classic four-prong basket that protects both pointed tips while allowing generous light to enter through the open cathedral gallery. Its elongated silhouette creates elegant finger coverage and emphasizes the graceful proportions of the center stone.
Round brilliant diamonds form delicate floral-inspired clusters beside the center, while marquise accent diamonds continue the flowing botanical theme along the shoulders. The slender comfort shank keeps the design refined and balanced so every decorative detail naturally frames the center diamond.
