Strange brooch possibly glass
Frank:
Or glass?
Pat:
I'll try to explain about the small chips. They are shiny inside like a piece of chipped glass looks under a chip, especially coloured glass, and the portrait looks more moulded than carved.
Frank:
Photo of the inside? Also try scratching with something other than a diamond.
Bernard C:
Pat — Withou looking at any of the replies here, I immediately recognised your fabulous broach as pâte-de-verre. It was cast from crushed glass coloured with metal oxides, then the mould was heated to fuse the glass, so the back will look rough.
The four main names associated with the technique were Walter (1870–1959), Bergé (1868–1936), Décorchemont (1880–1971), and Argy-Rousseau (1885–1953).

This is a beautiful and valuable piece of glass.
Thank you for the image.

B & M:
It doesn't look like pate-de-verre to me, it doesn't seem to show the granular appearance associated with the technique, though of course it is difficult to tell without handling the piece. The consistent white opacity and sheen seen on the face suggest to me that it may be milk glass with applied colours.
Edit. I may have been wrong with my previous line of thought, I should say it doesn't have the appearance I would associate with pieces by Almeric Walter or Argy Rousseau. I have just found this interesting site illustrating cabochons in pate-de-verre and describing how the use of finer powders allows for greater opacity and detail:
