Hopfully some clearer pics for better recognition of my not knows Two of the blue?? cryptocrystaline nature- blue chalcedony or perhaps agate? This pic is truer to the color and the second one is the backside with quartz thought I would throw these in also Priaday agate Kind of a unique ( to me ) quartz that I don't see much of out here where I'm at

I agree on the chalcedony , and is a nice one . I`m little less sure on limestone now . You sure that is quartz on it , or calcite ? either one is ok for limestone , but calcite is more often . The cut face does looks like limestone to me .
