Victorian Cameo Gold Filled in Lilac Brooch Pendant

A truly unique 12k gold filled cameo pin/pendant. The cameo is prong set in the center of a scroll frame. Back of cameo is the peach color associated with cameos, on top of that is a lovely lavender (not sure the material, feels & sounds like glass?) the lady is very detailed in it's carving. The metal frame was tested by an XRF alloy analyzer and showed to be 12k, picture of that test is the last photo. The Cameo measures 2-3/8" x 2-1/8" at it's longest & widest points. It has a C clasp and a fold over hook to attach to a collar.
