The circumference of the large glass around the bulged part is approx. 32.5" which divided by pi makes the diameter 10.345" across. The top glass that connects by chain to the bottom glass is 9.5 diameter. I will wrap the two glass portions separately and you will need to reassemble by hooking the chains to the top glass and bottom glass. The electric wire is old, so You may want to rewire it.
Please see photos for actual item and condition. I post feedback after you have received and posted feedback.
