can anyone identify this stone?

0 votes

I have two of these and have been unable to identify them. One is the size of a HONEY DEW melon. Weighs approximately 20lbs. The other is approximately the size of a basketball and weighs approximately 86lbs. They are extremely dense. Very heavy for thier size.

looks like a sliced and polished nodule or concretions, most like silica-based, which would classify it as agate or chalcedony. The exterior lattice-work is certainly interesting. What is the origination of these? And can you get a better and clearer photo of the frontal section where the specimen is sliced?

Chalcedony and chert are interesting conclusions. I thought they were concretions. The differing matrices were troubling me until you said it looked like it had been sliced. There are no layers, no conchoidal fractures, nope definitely not agate or chalcedony. More like a concretion than anything else...
