We love this vase, though not sure if it's Tiffin glass or Imperial? (maybe Consolidated glass?). The vase is separate from the stand, but the two pieces are an original set, I think. And we're leaving them together.
The vase itself (measured without the stand) is about 8 3/4" tall. Both the vase and the opaque black base are in excellent condition without chips or other damage. We're not positive on the age of this set - it's certainly vintage, but probably not antique?
