An Edwardian 18ct white gold brooch from circa 1910, designed in an openwork scrollwork floral style with blue sapphires and silver-toned diamonds. The composition incorporates three oval blue sapphires, with a central cushion mixed cut sapphire encircled by twelve claw set diamonds, complemented by two additional oval faceted sapphires and an asymmetrical array of individual claw set Old European cut diamonds. The pierced decorated oval scrolling frame is embellished with pavé set diamonds, and the reverse is secured with a hinged pin and clasp fastening. The piece measures 0.78 cm high, 3.9 cm wide, and 4.1 cm deep. This antique brooch is suited for wear on lapels, collars, or scarves during formal events, celebrations, and significant family occasions. Floral jewellery gained popularity during the Edwardian period to symbolise beauty, growth, and new beginnings.

Edwardian jewellery, crafted between 1901 and 1910, is known for light, airy, and delicate openwork designs often incorporating garlands, scrolls, and ribbon motifs using platinum or white gold settings.

Pieces from this period frequently utilised 18ct gold, platinum, old European-cut diamonds, and high-quality coloured gemstones such as sapphires, pearls, and rubies.

Authentic pieces typically showcase hand-engraved details, millegrain edging, antique gemstone cuts, period-correct hinged pin mechanisms, and historical makers marks or hallmarks.

Antique brooches are frequently displayed within velvet-lined shadow boxes, mounted on framed textile backdrops, or styled atop vintage jewellery trays on dressing tables.

Clean gently using a soft toothbrush, mild soapy warm water, and dry thoroughly with a lint-free cloth; store separately in a soft pouch to prevent abrasion to the stones and metal.
