Johnson, Walker & Tolhurst Victorian Yogo Sapphire Pendant Brooch

Romantic and exceptionally rare, this Johnson, Walker & Tolhurst heart-shaped convertible pin and pendant sparkles with pavé-set Yogo sapphires totaling approximately 15.00 carats. The sapphires are entirely untreated, and their vivid cornflower blue hue is animated by a lace-like border of natural seed pearls. The accompanying AGL report confirms the sapphires’ Montana origin and unheated state. Set in 14K yellow gold.

Yogo sapphires are mined exclusively from Yogo Gulch in Montana and are celebrated for their naturally rich color and exceptional clarity. Upon their discovery in the 1880s, Tiffany & Co. gemologist George Kunz famously described them as “the finest precious gemstones ever found in America.” Unlike most sapphires, Yogo stones lose intensity when heated, resulting in the vast majority being left untreated and entirely natural.
