This beautiful stone shows a chrysanthemum on the front and back. It was formed many millions of years ago by the rich mud being compressed at the bottom of the sea. The lower depths allowed the spectacular radial growth of celestite or calcite formations that remains as the flower patterns in the solidified limestone, dolomite porphyry or clay gypsum. It looks like an artist painted it...the artist was Nature. It is 9.25" x 4'75" x .50"
