A truly wonderful art deco American creation by Henry Kohn, circa 1930s. Handmade in platinum and 14kt yellow gold, this plaque brooch is set with 79 diamonds of G/H colour and VS-SI clarity as well as an 8.8ct mid-blue, eye-clean aquamarine, most likely a modern replacement.
For over 100 years, Henry Kohn & Sons was a high-quality jewellery institution in Hartford, Connecticut. Henry Kohn was born in Bohemia, Austria, in 1839 and came to America in 1865. Henry settled in Hartford, Connecticut, and started his small jewellery business.
Kohn's eponymous company was a retail and wholesale diamond and precious gemstone establishment that enjoyed much success. An 1886 article from the Hartford Courant stated that Kohn "is everywhere recognised as a gentleman of superior business attainments and thoroughly affable ways and manners."
