What is this thing? (Moved from GD)

Roughly 9 years ago, I walked into a thrift store for no real reason. I was drawn to a shelf in the back, I reached into a pile of picture frames and candlesticks (every thrift store right?) and pulled this tricky guy out. I briefly had it in a cabinet a couple months ago, but the cabinet has a mirror backing, and odd things happened. (My reflection became nearly translucent.) I try not to touch it much anymore, because when I do, I just do not want to put it down. Also, the chips and scratches come on their own, as it spends allvof its time on that shelf. I’m curious of what it is, why we were drawn to eachother, etc.
Thank you.
