Pipe Crystal Boulder Opal
Pipe Crystal Boulder Opal is a unique type of boulder opal that is sandstone based, apposed to the regular, more well known ironstone based boulder opal. Sandstone is more fragile, brittle and lighter in comparison to the ironstone. The precious opal itself is lighter in colour and is crystalised, apposed to boulder opal which is not. Crystal opal is transparent, meaning that if there is no sandstone backing on the precious opal, that you could see light ﬁltering all the way through. If you shine a light behind the crystal you should see a diﬀerence in the colour and pattern change. Compare that to ironstone boulder opal and you will not see any diﬀerence should there be light shining on one side of the opal; it is a non-transparent type of opal.

The opal ﬂuctuates with discoveries; some years the mines can discover good size pockets of pipe crystal, while other years not much has been discovered at all. In a some of the mining areas of pipe crystal, miners have discovered crystallised dinosaur fossils, tree roots, wood fossils and other miscellaneous objects.
Pipe Crystal gets it name because it is formed in pipe pockets in the Earth. Imagine an ants nest that has diﬀerent cavities and larger pockets in the ground; this is the same ideology as where pipe crystal is found. Miners break oﬀ chunks of large rock with ﬂecks of crystal in it and sell these chunks to cutters who then break them apart and cut them into sizeable pieces for polishing. Another popular item amongst buyers with pipe crystal is the pipe crystal shards; raw pieces of oﬀcuts of pipe crystal that have been put into jars for either souvenirs, making into raw jewellery or for polishing and using in smaller pieces of jewellery.
