Boulder Pipe Crystal Opal is found in the Central Queensland opal fields in Australia. As the name suggests it is opal formed in a pipe or tubular formation. These roundish tubes are formed in the host rock, which is mostly sandstone. The sandstone potch enhances the natural fire color in this crystal opals. Most pipe opal is green to blue fire colors but some have sunset bright fire opal colors but this is rare. The tubular pipe opal can be hollow or tubular.
