This is a glass kaleidoscope embedded with minerals. I purchased it 12 years ago. It has a considerable weight to it. The size is about the same as the palm of your hand. It's a rare item that you won't see anywhere else. I have kept it carefully, so there are no scratches or damage, but please refrain from purchasing if you are overly concerned about minor imperfections. Please feel free to inquire about your desired price. #kaleidoscope #minerals #ornaments #antique #rare #one-of-a-kind #antique #naturalstone
