Boulder Opal is a ironstone or sandstone rock that contains thin seams and patches of opal surrounded by or attached to its natural host rock. It forms when precious opal carried in silica-rich water seeps into cracks and cavities of rock, invertebrate fossils, and even petrified wood.
The opal in these types of rocks is often too small or too thin to isolate and cut into a solid opal. It is also too beautiful and valuable to go unutilized. So often the whole rock is cut and polished into a gemstone that displays the natural seams and patches of precious opal exactly as they occur within the host rock.
Australia is the world’s most famous source of boulder opal, with much of it coming from the Koroit Opal Field of Queensland, Australia.
The name Opal comes from the Latin word opalus which means "precious stone".
Metaphysical Properties: Opal is said to assist one in becoming more positive and loving.
