Retro Porcelain Painted Cameo

This is a fabulous find from the bottom of an estate sale jewelry box. This retro pendant is a beautifully painted porcelain miniature cameo of a woman in a powdered wig accented with real jewels. The glass panes float two gemstones: one diamond-like creating an earring and one ruby-like creating the pendant. The outside frame is textured and pierced white gold with stamps on the bail. The bail is stamped 750 and Z71 A(illegible letter). This pendant and brooch combo has been additionally verified as 18K white gold through testing. I believe this style is linked to the designer Corletto based in Italy beginning in 1963. I could not verify hallmarks and have not opened the back frame to look for additional stampings. The miniature painting is incredibly fine and is near identical to the hallmarked images credited to designer Corletto. This item weighs 7 grams, stones included. \
