I made this pendant from a vintage, hand carved cameo brooch. The cameo was loose in the setting and fragile so I used 2 part epoxy resin to preserve it for the next 100 years. The resin has a hardness on the mohs scale of 7. It is as hard as quartz without being as brittle. Then I added a glue on bail with the same resin.
Measures 1 1/2 X 1 3/4 high, not including the bail.
The last picture shows a pile of hardware I removed from a few hundred vintage brooches and dress clips (slight obsession).
