Question re Monet bracelet

[pheasantvillecollectables519]

I see almost identical toggle bracelets marked Monet listed on ebay but mine is not signed.  It does however have a little M charm.  I have a different signed Monet bracelet with an M charm -, solid, not open like this one, and it is the same squared looking M. 

So my question is, does Monet sometimes use the M charm as its signature? Although I don't know why they wouldn't sign the bracelet on the round part.

It kinda looks like something is on the rounded pc?  I tried to enlarge  & crop but  your pix is too small. 

I havent checked the latest Monet items in stores..so dunno if they are doing the initial or not

The circle has pave crystals on it - the underside of it is just plain, nothing on it.
