There is very little of this rough available most of the time. Yowah nuts are formed naturally in siliceous ironstone nodules generally referred to as a Yowah Nut. Yowah Opal fields are mostly worked by hand rather than by machinery and many Yowah Nuts are found by fossicking. A few open-cut mines have recently opened up large-scale opal mining. The Yowah Opal Festival is held mid-July and includes a jewelry competition.
