Cameo Stick Pin Antique 10k Yellow Gold Hand Carved

Antique 10k yellow gold and hand carved conch-shell cameo stick pin.

The cameo has not been cleaned, but I have found that collectors like them just as found so I have left in original condition.

It is marked 10k on the back. It has a clutch that I believe is not precious metal as the pin is. 

Cameo with setting measures 13mm by 16mm. Pin is 2 3/4" long with the clutch. 

It weighs 2.1 grams.
