Well I was looking up some information about patent leather and found out it was invented in Newark New Jersey by a man Thomas Edison titled the second greatest inventor (after himself), Seth Boyden. Mr. Boyden invented a "fancier" looking leather which was conditioned with a layer of linseed oil and was stiff and shiny. He created patent leather in 1818 and by 1819 it was a commercial success. Unfortunately he never patented his patent leather and did not receive monetary success. He later would invent malleable iron.
I am most familiar with patent leather footwear an have never seen it in a cuff form.
Was this a manufactured bracelet from New Jersey's booming Newark?
Is it possible that the bracelet is a piece of mourning jewelry? Or was she proudly displaying a something completely unique?
What do you all think?
