Antique coral and filigree brooch or pendant

Lovely piece that seems to have been made to be used as a pin or perhaps a pendant. It's complete, but there is no "fixing" at the back (and there obviously never was). It could be used to make a beautiful piece of jewellery of your own design. There are holes at either side for attaching to a necklace chain.

About 2.3 inches long—6 cm.

The piece of coral is really quite a good size, about 0.2 cm across. It seems to be genuine, old coral.
