home / agates worldwide / Asia / peoplesrepublik of China / China Thunderegg

Sometimes one had to appear - here it is: the first Thunderegg (lithophysae-agate) from China. The precise discovery site is still unknown to me - if someone knows some  details to the location, I would be very grateful for the information. The agate is not unusually formed in this Thunderegg - but the matrix is showing  its spherulitical nature in a detailed way.
