Vintage Mid-Century Modernist Gold Plated Opal Brooch Pin, Rollover Clasp Unmarked, untested. Selling As-Is but it's a beautiful piece! Clasp works great, the gold tone metal just needs a little polishing. Assumed to be gold plating, shows oxidation throughout. The blue opal stone at the center has brilliant flashes of red (see video) Lightweight estate piece, comes directly from my family line.
