My Mom's cameos. My sister kept one and my brother kept one for his wife, but I got the rest of them.
Mom bought carved shell cameos and Wedgwood in the swinging 60's in the Portobello Road Antiques Market in England. Everyone wanted Mod, but Mom loved the Regency and Victoriana. The top two are cameo habillé (the ladies are wearing real diamond jewelry.
A rustic scene (Rebecca at the well?) mounted in Pinchbeck. Pinchbeck is a form of brass, an alloy of copper and zinc, mixed in proportions so that it closely resembles gold in appearance. It was invented in the 18th century by Christopher Pinchbeck, a London clockmaker.
It swivels to reveal Victorian hair work on the back under glass. The swivel pin is loose, so I don't think this is wearable since the center tends to fall out.
