Do not know for sure what this is? Chalcedony in sugar quartz. Before tumbling: The before photo looks like a Stromatolite or some type of fossil, organic material. Just prior to going in 1200 AO: Some of the sugar quartz ground off and the chalcedony areas ground down a little. That left these cool plumes and pockets of quartz crystals. Another thought is the remnants of an ancient stalagmite. What do you think?

It's not Stromatolite, more sugar quartz than anything... Looks cool though.
