What is this???

This container is stunning. I picked it up at a garage sale and I just love it. I can't find anything like it online under vases and decanters. It looks like clear glass with white glass encased inside except for the clear windows. The color is an iridescent golden brown. the pontil looks somewhat like thumbprints. It measures approx. 6.5" x 6.5". Does anybody know what I have here??? Thank you in advance for any help you can give me.
