For sale is an opal fossil clam shell, from Coober Pedy, S.Aust. This bi-valve opal fossil is complete all round save for an couple of minor nibbles, uncommonly the specimen is solid opal thru out, which is revealed by shining a strong light thru the specimen. There is not internal clay or sand!! There are several areas that have hints of purple blue. So its possible this piece could take a cut or polish and reveal better opal play of color. I wont guarantee this, but it is possible. The shape and form of the opal replacement fossil shell is excellent. These fossil shells are approximately 110 million years old.
