This Victorian era cameo c1880s does not have any makers marks or other markings. It has been safely tested and is guaranteed to be at least 10k gold.
The Cameo pendant has an ornate setting. This piece measures 1.25" X 1" and has an oval shell carved cameo (3/4" X 1/2") at the center. The details on the piece are very nice with a fine sawtooth edge on the cameo setting which is then bordered by a rope trim before you reach the ornate frame.
The weight pendant is 5.3 grams.
This would be beautiful on a long or short chain. I think it would also be great on a ribbon as a choker - just need to add a larger bale but that is a couple of cents.
