I think there is a wafer between the top and bottom. It could be part of the mold (see picture #3 & #4).Period glass fluoresces under the black light (see picture #7). It is about 5 1/4" tall x 3 7/8" wide at the top. It is in excellent original condition.
I can only find a couple of small very hard-to-notice insignificant chips under the upper rim. This piece has a great antique feel that displays exceptionally well. My pictures don't always project the ideal image. I have serious problems with glare and lighting. Please don't hesitate to ask any questions, especially photo related ones.
