MSH Glass Apple Paperweight

Paperweight is 4" high by 2.5" across. Base engraved" MSH the glass eye". This company from Washington incorporates rock and dust from Mount St. Helens in their glass objects. This is the only one of theirs that I have seen that combines the iridescent coating with small controlled bubbles and a larger single bubble in the center. The coolest part of this is if you enlarge the pic, you can see reflections of the smaller bubbles in the surface of the large center one. This came from a thrift store called Savers.
