Buy Boulder Pipe Crystal Opal
Boulder Pipe crystal opal, only small percentage boulder opal forms as pipes and most is crystal opal and as the name suggests, the opal is formed in pipe shape tubular holes when formed in the mother rock,
Pipe opal forms in running lengths in the sandstone potch in single line or multiple fragments.
The darker the sandstone the darker is the opal colour.
If the opal cutter cuts away the potch of the opal could be lighter and translucent, so most opals have potch or sandstone covering sides and bottom.
Large pieces crystal opal do have striking patterns and most people would not realize the opal is boulder opal
The pipe opal can be solid or tubular and when tubular with hole it is sometimes confused with belemnite opals.
