Opal and Filigree Necklace

Gold color metal filled with swirling wire in a filigree motif. Small enameled leaf elements. 3 small oval, genuine Opals. The stones are not high grade but do flash fire when the light catches them. 1.5 inch circle, plus bale. 18 inch chain is not original to the piece but, marries well. Ca., 1970's and is in very good condition.
