Hi Blair,
I remember seeing another vase in amber and gold flecks with hanging rings like yours, but it was Salviati (the sellers attribution), and much more ornate. It had a lot of scroll decoration on the handles.
Yours does look like an older piece, but I am thinking it shouldnt be so clean and sleek. Also the large snails applied to it seem a little weird to me. Worth a look at Laura's suggestion.
