I know I've seen that ERE before but I can't remember who it belongs to. The Hougart book says ERE is sometimes seen on Eric Hult de Corral but the section on her marks doesn't show the ERE just her Ric mark.
The stone looks like it may be a lab created Alexandrite, does it change color from purple to a bluish green?

Thank you so much for taking the time to check the marks out. I thought I had looked at all the examples on the site; but even by comparing workmanship, this bracelet really resembles the work style of Erika Hult de Corral, especially in the hinge mechanism.
As far as the stone goes, I've had a couple different people look at it and have gotten created Alexandrite, Amethyst, and true Alexandrite (which I don't think it is due to the real deal being so rare in such a size). I haven't gone to a jeweler though.
Again, thank you for your input.
Regards,
Maureen
