Domed glass insert fits inside the frame - some may have tiny imperfections which just add to the aged look - just add a picture printed out or some nice solid foil and cut to size, glue to the bottom of the glass, then glue glass into the frame.
The last pic is example (not included) of using the foil wrapper from an easter ham as the color base to get a deep purple gem look. A nice way to recycle foil food wrappers :)
6 pieces total: 3 oval frame connectors and 3 oval glass cabochons
