Late renaissance memento mori skull ring. "Memento mori" jewelry translates to "remember thou must die", a reminder to all to live life fully, as death awaits. Memento mori rings were meant to encourage the practice of reflection on one's mortality. This is a very early Swiss ring with black enamel etching along the sides and back and a perfectly shaped skull in intaglio on the front. The ring is silver gilt with black enamel carving. Circa 1620. US size 8 1/2.
