These opalized clams are sometimes polished to show the flashy colors all over the specimen, which is certainly an option with this specimen. It is actually rather lucky that there are a couple of dings on this fossil clam, because they allow you to see that the inside has been entirely replaced solidly with OPAL without polishign the whole thing. This is quite large for one of these, weighing 25 grams. That is a lot of opal! Ex. Richard Hauck Collection. 4.5 x 3.8 x 2.0cm
