This lovely little thing is marked M&M, signed ‘by Michele’ and marked 925. It also has a hallmark which I simply can’t read. So many marks and still no idea where it is from?
gems tested as genuine, but not sure what!
They look like amythest !!.
Have you tried a USB Microscope to obtain clearer pictures !!. They’re cheap but effective 
i bought one 
still no luck
I’ve had one for years Karen, they’re cheap but effective if used properly.
Also I sometimes use a decent size loupe places in front of my phone camera and experiment with the more difficult to get at marks . Hope this helps and have a pleasant evening
