C.1870 shell cameo of a bacchante 14ct gold and enamel brooch

A very finely carved 19th-century, c.1870, shell cameo of a Bacchante or Maenad in a 14ct gold (electronically tested) and white enamel archeological revival brooch mount. There is a ring to enable conversion to a pendant if desired. There are faint (too much so to photograph) initials, possibly LK, at lower right on the back of the shell.

Height: 1.7in (4.3cm)
Width: 1.4in (3.7cm)

Condition: In very good condition. No damage to the cameo apart from a small scratch on the back. It is secure in its mount. Minor (hardly noticeable to normal viewing) enamel losses in the ovals at the upper left of the surround (approx 10 o’clock, see images), a small ding at the back (not visible from the front).
