This Faux Gemstone Glass Pipe with a Metal Bowl combines the durability of a metal bowl with the unique shape and designs that can be achieved with glass. The glass stems of these pipes are a 3 chambered design with faux gemstones in the middle chamber. These gemstones help diffuse the smoke as it comes through the pipe making it cooler and smoother. The metal bowl attaches to the glass stem with three rubber grommets to ensure an airtight seal.
