Other Information:

* Boulder opal defined: "Much precious opal occurs as thin seams and patches within a host rock of ironstone, basalt, rhyolite, andesite, quartzite, sandstone or other material. Some precious opal also forms within the cavities of fossils, concretions, and nodules. The opal in these types of rocks is often too small to isolate and cut into a gem composed only of solid opal. It is also too beautiful and valuable to go unutilized." - Source: Geology.com
