GEORGIAN MEMENTO MORI SEPIA ON IVORY SKULL AND CROSSBONES RING

This is an antique Georgian high carat gold content memento mori ring with a watercolor sepia of a skull and crossbones on ivory under a glazed compartment. 

There are willow branches in the background which symbolize mourning. 

The rear is inscribed to a married couple with the same initials, "S T," who died two months apart in 1802.  It is absolutely stunning.
