Victorian Turquoise Locket - Gold Filled - Antique - As Found

Incredibly rare Victorian Turquoise large locket with original tin type photos.  Locket measures approximately 1.25 inches (2 inches with top bail) x 0.75 inches.  Has beautiful rose gold ruffle under Turquoise.  Does not stay closed.  Price reflects.  Likely an easy fix by jeweler as it has a mechanism to stay shut but leaving to new owner to work with jeweler.  Faded darkened gold color.  Likely gold filled.  Note top bail has an open back hook design.  Believe this would have hung on a beaded strand.  You could change it out but would be removing Turquoise at the top.
