This is a BEAUTIFUL miniature glass mushroom paperweight/sculpture made by J.J. Bloemer at Boomwire Glass in Ohio.  The mushroom is made of borosilicate glass and features an AMAZING blue, green, and gray swirl design on a clear glass mushroom stem.  It's a miniature paperweight that is about 1 inch tall and 1.25 inches in diameter.  This was made by a process called lampwork, where a torch is used to heat the glass enough so that it is malleable and able to be shaped into different shapes.  This item is, essentially, new.  It was purchased recently directly from the artist.
