Edwardian Ostby & Barton 14k Two Tone Gold, Sapphire, and Pearl Filigree Bar Brooch

Created circa 1910 by the celebrated American jewelry firm Ostby & Barton, this refined Edwardian bar brooch exemplifies the grace and exceptional craftsmanship of the early twentieth century. Founded in Providence, Rhode Island, in 1879 by Engelhard Ostby and Nathan B. Barton, the company became renowned for its finely executed gold jewelry and intricate die-struck designs. Pieces bearing the coveted "OB" maker's mark are especially admired by collectors, not only for their quality but also for their historical significance. Engelhard Ostby was among the passengers who perished aboard the RMS Titanic in 1912, lending surviving examples of the firm's work an enduring place in American jewelry history.

Expertly fashioned in 14k yellow and white gold, the brooch showcases the delicate filigree and airy elegance that defined the Edwardian aesthetic. At its center rests a vibrant round sapphire weighing approximately 0.15 carat, flanked by two luminous seed pearls. The harmonious pairing of sapphire and pearls, symbols of wisdom, sincerity, and purity, was especially fashionable during the Edwardian era, while the slender bar form reflected the period's preference for refined, understated sophistication. Beautifully preserved, this brooch is both a wearable work of art and an exceptional example of one of America's most esteemed historic jewelers.
