pretty but unusual button

[NGE]

I found this button a few years ago, in an older park. It's a little bigger than a U.S. quarter, appears to be made of brass. And has metal stones attached by being peened on the backside. The loop appears to be brazed on. I know it looks victorian, but what I want to know is, has anyone seen another like it, none of my friends or older relatives have, and I have some dinosaurs in my family . An approximate age would be nice. And because it looks expensive, is it? Also, there are no back marks whatsoever............NGE
