From our Estate Collection, a captivating mid-20th-century floral brooch crafted in luminous 18K yellow gold with platinum-set diamond accents. Designed as a bouquet-inspired spray, this elegant piece features flowing gold stems adorned with vivid blue sapphires and a ribbon-shaped diamond motif at the base. The expressive form and mixed-metal construction reflect the refined artistry and romantic symbolism of classic floral cluster jewelry.

Twelve round brilliant-cut natural sapphires are prong-set along the upper stems, while twelve old mine-cut diamonds are bead-bright set in platinum, adding delicate sparkle and contrast. A graceful and collectible statement piece embodying timeless craftsmanship and period charm.
