This refined antique diamond brooch dates to the Belle Époque (circa 1890–1910), a period celebrated for its elegance, optimism, and extraordinary craftsmanship in jewellery design.

The brooch features a harmonious circular composition, delicately interwoven with floral and leaf motifs. This airy, nature-inspired design is characteristic of the Belle Époque, where jewellery was created to appear light, flowing, and almost sculptural rather than rigid. The refined openwork enhances movement and allows light to pass through, increasing the brilliance of the diamonds.

At its heart are exceptionally white old-cut diamonds, remarkable for their brightness and lively sparkle. Old-cut diamonds are known for their broad facets and soft fire, yet these stones stand out for their unusually crisp white appearance. The warm glow of 18ct rose gold provides a beautiful contrast, emphasizing both the diamonds’ clarity and the elegant lines of the design.

A historically significant and aesthetically timeless piece, ideal for collectors and connoisseurs of fine antique jewellery.
