I was informed that this paperweight is Murano.  Unfortunately, I am uncertain of this paperweight due to the seam or annealing fracture that runs straight thru the middle of the paperweight.  This was caused by improper cooling of the molten glass as it was being made.  It's a mystery paperweight, so willing to entertain offers.  The design seems to be pansies or similar flower.

I looked it over closely and found no scuffs, scratches or bruises.  Glass is clear with no hint of cloudiness.  3.75" wide and 2.5" high.  Smooth polished base, does have tiny air bubbles
