Ask Peter About This Item
Interesting ironstone patterns with some green boulder opal features.Yowah ‘nuts’ get there name from the fact that when they are found in the ground, they resemble nuts that have fallen off a tree, but when they are sliced, it is often discovered that there is a kernel of opal. of course, this event is very rare. You can cut or break many thousands of nuts without so much as finding a flash of color. This is what makes them such collectors items. this particular piece is Yowah matrix.
