How cool is this!?
A giant Victorian paste crescent, the pastes in silver pinched collet settings with foiled closed backs. And these pastes are sharp! Cristal clear and shiny AF.
Converted from a brooch I had the large gold ring hand made for it to be in the correct chunky proportion. 
 
Looks perfect on a chunky gold or silver chain and worn quite short.
