Nettie Rosenstein Clutch

When my grandmother died there was an estate sale of her things and I bought this clutch. That was 8 years ago and it's been sitting in my craft room in a box ever since.
All I know about it is that it says Nettie Rosenstein on the inside. It is all beaded in gold beads and has glass stones on it as well. It has red velvet lining and also has a mirror case in red velvet inside it.
Can anyone help me to know where I can learn more about its age and worth?
Thank you,
Pam
