A 1950s large gold tone metal pendant, with lots of detail, textured circles, and scalloped edges.  There are two colors of green, a clear and amber stones.  The center has a circle border of clear stones around a high domed amber cabochon.  No makers mark on this.  Pendants are more unique than brooches.  On a gold tone chain, that probably needs replacing, it has some wear to the plating in places, as shown.  Thanks for your interest!
