Weird 02 weight: 19.4 grams total. Size: 39 x 30 x 13 mm. when fitted together. Boulder opal split from Quilpie, Queensland. What do you suppose was in this stone 12 million years ago that prevented the opal from filling the center? It was empty when we opened it. The ironstone backs are polished.Could make a strange pair of earrings, or two parts to a belt buckle.
Price: $185 U.S.
