This is blue and white sodalite which we received in a bag of rocks to tumble with one of the Rock tumblers. I believe these pieces came with the National geographic but we might have come with the Evans or the stemrock. We do go through an awful lot of tumblers.

We have two pieces of sodalite material which has the characteristic blue and white colors which sets it apart from lapis. These two rocks are ready to tumble or will be perfect as crystal specimens kept raw and natural.
