A lovely double coil Egyptian snake bracelet made with 90% pure silver and decoarated with turquoise and has coral insets for eyes.  This glorious snake bracelet had a gold gilt at one time, but now it all but gone. It has the assay mark on the back of the head and a very faint and now illegible three part Egyptian hallmark on the twisted cable body. Based on other bracelets of its kind, I'd say it's form the 1940s and made in Cairo. These are classic bracelets that are never out of fashion and a real collector's item. 

Body measures 41.5 cm (16 1/4") from head to tail.
Inner coil's circumference is around 21 cm (8 1/4"). Inner diameter is 6 cm (2 1/2"). Weight is 39 g.
