How can I tell if my coral cameo is real?

There are a few tell-tale signs you can look for to determine whether your coral is real or fake. One thing you can do is hold your cameo up to the light and look for a silhouette of the design; a real shell will show an outline. You can also try the hot needle test by placing a hot needle on the cameo. If it’s plastic there will be some melting.
