Vintage Italian pendant in silver with turquoise

This is one of three similar pendants that were bought by a friend's parents in Italy in the 50s or 60s. It's the smallest of the three, at about 3/4" in length and 3-4g in weight. It features four round turquoise cabochons around its circumference, and another at the bottom. There is a mark on the bail that I think is 800, and the piece has been confirmed as solid silver. In very good condition, with an antique finish which I believe was intentional. (ga)
