Lovely vintage Avon necklace features a clear crystal Topaz tear drop center situated in a lovely silver tone filigree pendant that hangs from a fancy silvertone chain. Measures 18 3/4 inch long loop to clasp and is in very good condition. The stone is set in such a pretty heart like shape with the top crossed bands and measures 1 1/2 inch in length at widest X Height 1 1/2 inch. and wonderful embossed patterns marked Avon on the pendant back and also has the attached tagged Avon loop. It is just beautiful. Best Guess Circa 1970s to 1980s. May be part of the precious pretenders line. But, they made mostly gold tone items in the precious pretenders line. Precious pretenders was the first Avon Jewelry line in the 1970s from my Avon understanding.
