Cobalt Blue Bubbler with Opal

Extra large glass hammer pipe, displaying an awesome, one of a kind silver fumed coloration between layers of clear and cobalt blue borosilicate glass. The super long chamber features a perfect donut hole right up near the neck and next to the bowl is a clear marble containing a massive chunk of rainbow opal. A little hard to tell from the pics, but the opal is huge and it displays some amazing color.
