Chrysanthemum Stone Rubbing Stone
The composition of Chrysanthemum Stone is variable.
Material from the occurrence at Yonghe in Liuyang County of Hunan Province consists of Celestite, but specimens recovered from outcrops of the same strata at other places in the area are mostly mixtures of Calcite, Chalcedony and minor Dolomite and Andalusite which replace earlier Celestite.
The minerals are arranged in Chrysanthemum flower like pattern.
Japanese Chrysanthemum Stone is aragonite (or calcite pseudomorphs after aragonite) in schalstein matrix.
