Looks very similar to pieces of Savannah River Agate that I have collected. I have found numerous pockets inside the agate that are crystalline lined, much like miniature geodes.

Fredda that looks like a little quartz crystal vug or chamber for sure. Like a thunder egg or the little beautiful chambers you get in agates. Now the blue stuff i don't know. Where did you find it ? How big is it ? How hard is it ?

Dug, you are quite possibly right. Thanks-- CST-- Dau, Chris, got this piece on ebay a year or so ago. Pic is no longer there. Could be the savannah blue agate that Dug mentioned, she thinks. As for size, its appox 1-1/2" X 3-1/2". An end cut that she had gotten with others. Hardness-- I can scratch it with a clear quartz crystal. Thanks for asking. fredda |

I've found many rocks with little crystal pockets like that recently. None are in such a pretty rock as that but the crystals look exactly the same. I believe that the rocks that I've found the crystals on are chirt? I'm still learning my basic rocks but I think that's right.

If the light parts are a yellowish material, this looks like a piece of a septarian nodule from southern Utah. It is fossilized old seabed and is a bluish, greenish grey with yellow splotches. They have openings filled with quartz crystal and sometimes calcite crystals to add interest. One of the people on our last field trip found a fossilized bone in the geode center of one. The claim owner let her keep it and told her it was worth at least $1000!! What a find.
