Tiny Tuesday - MIneral

I have a collection of brooches that belonged to my mother and grandmother.  This is one of them.  I thought it a bit unusual because it's a fly and looks to be a peridot for the head and inside the body.  One of these days I'll photograph them all.  When I worked I used to wear blazers and jackets and I would always have one pinned to the lapel.

Some info on a peridot.
