This is the back of the brooch setting, does look shell like.
HH Robert.
That's a tarnished metal back for the cabochon on the front.
Forgive my ignorance Alnitak, But what's a cabochon ?.
It's a type of polished cut stone. Typically it will be backed with metal when made into jewelry. Malachite is a very popular rock to use for cabochons due to the unique patterns and green colors. Here's a modern polished malachite cabochon:

Typically brooches or pendants are where you see cabochons used in jewelry. Here is a little more on cabochons on Wikipedia:

The one you posted looks like a malachite cabochon, probably with a silver or other metal back. What does the other green side look like cleaned? It could be shell, but it looks so much like malachite, and that's such a common semi-precious stone used for those purposes, that I doubt it would be shell.
