This is a gorgeous large Dynasty Gallery Ice Cave Teal Glow paperweight.  (currently not available from their gallery).  The colors and design were inspired by the Mendenhall Glacier and created by layering molten glass between 1500-2000 degrees.  It measures approximately 4 1/2" in all directions.  It has a soft subtle glow in darkness.  There is a small scrape or flaw in the glass on the underside of the globe that I couldn't photograph because to looked like the glass.  It it hard to see.  It weighs a whopping 2 1/2 pounds. This is a stunning piece of modern glass art!
