Mid-19th century. A light, almost moonstone blue sapphire has been carved into a classic female profile. The frame is a delightful combination of emeralds and red, white and green enamel. The cameo and frame more than likely once served as a pin or pendant and was expertly converted into a ring long ago, perhaps by the original maker since the engraving on the under gallery is virtually indistinguishable from the engraving under the frame.
