Hi Chris!
Thank you so much for looking at it.
The opening is 1.5" measuring from one side to the other- the diameter as a whole is just shy of 2" and the total circumference is 7"
The base circumference, at its largest point, measures 20" around.
I am not sure what's going on with the bead job up top.:) The exterior presents of hot glue leads me to believe a valiant effort, but poorly done craft job is behind the beads. As esthetically displeasing as they are, I was told the beads are gemstones assumably from an older piece of jewelry. There is a bevel or lip that the beads cover (see pic). Something may or may not have been there originally but I'd love to know what the heck this is. I've never found such difficulties attempting to identify something:/.
Lamp? That's an interesting possibility. However, Im not seeing a drill mark. Would it require a certain angle of light to see it?
I do see what I thought was etched marks but it's also highly possible they are scratches. The base also has some marks that may be construed as identifying but then again my newly found interest in glass makes me less than capable of being able to distinguish flaws from facts to normal wear and tear.
Thanks again for your time! Any additional info/ input you may have after reading this would be much appreciated.
