This is a lovely vintage gold tone frog brooch with a rhinestone body, emerald cabochon eyes, and blue, red and green cabochon . Gold tone setting. It is unsigned except for the numbers, A2166 which is a Sphinx marking. The Sphinx Company 1948 thought the late 90's was a well-known British jewelry company that produced skillfully crafted costume, made to look like the "real" thing. Some pieces, like this one, have the letter and number mark included without the Sphinx name. It is in excellent condition with all stones intact. The only thing I see is around the large oval green cabochon which can use a little cleaning. The pin and clasp are secure. There are no repairs or damages. The brooch measures about 1 1/4 inches. It's lovely!
