This is a Cool Silver Spider Stickpin that has a cab of Turquoise on the Spider's back. It looks like it may be from the Bizbee mines gemstone. It measures 3 " in length, the spider measures 3/4" long by almost 2" long with his 6 legs extending. The Pin Part appears to look like silver as well. The Catch / Cover over the Pin Point is not Silver and is more than likely silver plate. We didi not find a mark on it, however, it polished up very nicely and looks like Sterling.
