How do you tell if a cameo is real?

To tell if a cameo is real, look at it from the side. On a real cameo, the raised decoration is a part of the stone, so you won't see any gaps between it and the rest of the piece. The raised design is usually glued on with reproduction cameo jewelry, making it possible to spot a gap or seam. If questions remain about your piece, have a certified appraiser or knowledgeable jeweler evaluate it. Find a selection of cameo jewelry on 1stDibs.
