PLEASE HELP I/D

Hello everyone I purchased this cameo today and can't seem to find any info no maker mark the meteral it's make of feel like a shell texture or maybe glass not shure 2 pictures of cameo with no light and one sitting on top of a flash light any info of age would be great... thanks.

 

Appears to be a shell cameo in a sterling mount with a broken pin back.
My guess, early 1900s.

 

She's the goddess Flora. Italian carving shell cameo. From the design of the lady herself, I'd think late 19th century but the setting is later than that. That clasp is much later; my guess would be 1950s on that part. It doesn't look like a marriage, but...coubbe.

 

Thanks a million everyone for your thoughts and info.
