The 1900 Exposition Universelle was held in Paris between April 15 and November 12, 1900. Farnham designed a life-size iris brooch composed of 120 Yogo sapphires and accented with diamonds, topaz and garnets inset in platinum. The brooch was purchased by American collector Henry Walters for $6,906.84 (comparable to $ today) during the Exposition and the brooch is currently in the collection of the Walters Art Museum.
