Posted this on the Jewelry board & they suggested I try over here. I'm not familar with this brand, picked up from an estate. From what I have researched everything looks good, my only question is that I see some bracelets are marked "Made in Austria", while others are marked "Made in Austria with a letter or plus sign afterwards. Why the difference?
Hermes is one of the designers that sued Ebay for allowing fakes on here..Id say take it to Hermes for authentication..very very expensive brand name.
I agree with Dee that the only way to know for sure is to bring it to an authorized dealer for authentication.
In the meantime, the above website gives some information that may be helpful.
