Vintage Butterscotch Amber Rectangle Cabochon Brooch Pin Brass Setting

Beautiful vintage rectangular brooch featuring a domed butterscotch amber cabochon set in a warm brass-tone bezel. The amber has a creamy swirl typical of natural butterscotch Baltic amber, with small black inclusions visible throughoutlikely bits of ancient organic material naturally trapped in the resin. The piece fluoresces under UV light, consistent with real amber. The pin back appears to be a later replacement, securely attached with adhesive. Good vintage condition.
