When I was in high school circa 1975 my BF, Susan, was sporting silver bangle bracelets crafted by a brilliant silversmith, Ed Levin. His small collection was sold out of the local ladies shop, Town and Tweed.
I coveted Susan’s bracelets and was, after scrimping and saving, able to buy myself a then very expensive pair of silver earrings. I loved them and wore them constantly. Sadly, at some point I lost one. 
Recently, in my post retirement clean-out, I found the single still fabulous earring. In the vast reaches of the internet I found that the Ed Levin workshop still exists in Cambridge, New York and that they had all the original designs on file for re-creation. The website sent me to a local dealer to have my earring sent for “refurbishment” and a copy made.
A few days ago I picked up my “new” earrings. I paid twice for one what I had paid for the pair 40 years ago – not so bad really. But, I am sorry to say I was disappointed. The match is okay, but not even close to perfect. I will wear the earrings; the original in my left ear, the copy in my right.
The artist can be copied but never duplicated.
