Gold pendant on chain in presentation box

A gold coloured pendant with an intricate stamped design on a fine gold chain, presented on a red background in a paper box.  It is not wearable at the moment but could be made so as the red insert is removable and the ends of the chain could be joined together.  The box is of paper and has a black line on the back for some reason.  I think that this may have been from the 1980s.  

15/16 inch (2.4 cm) wide, 1 1/4 inches (3.2 cm) tall.
