Here's a wonderful pair of Sterling Silver signed DaVinci cuff links. Marketed under the Lucien Piccard label in the 1960's, are 3/4" long & 5/8" wide & weigh 17 grams. They have black & green vibrant enamel on the top. They have not been polished, so have very nice dark patina, but they will polish up to a bright silver if you prefer; I will be happy to hand-polish them at your request after you purchase them. They are in excellent condition and can be worn by either a man or a woman equally well.
