Why This Piece Is Special

Colonial Australian jewelry, particularly from prominent makers like Frederick Bassé, is highly sought after by antique collectors worldwide. Bassé arrived in South Australia from Germany in 1881 and established a reputation as a master diamond setter and fine jeweler in Gawler Place and Rundle Street, Adelaide. Authentic marked examples of his work are becoming increasingly difficult to find on the market.
