Physical properties

Formation & geological history

Formed in marine carbonate deposits through geochemical processes where strontium-rich minerals or andalusite crystallized into radiating, flower-like patterns within a limestone or dolomite matrix over millions of years (Permian to Triassic periods).

Uses & applications

Used primarily as decorative ornamental stone, carved into sculptures, polished as display pieces, and collected by mineral enthusiasts.

Geological facts

The distinctive flower-like patterns naturally resemble chrysanthemum blossoms, which hold deep cultural significance in Asian art and philosophy. Authentic stones are often hand-carved to enhance the contrast between the dark matrix and the white crystal 'petals'.

Field identification & locations

Easily identified by the stark contrast of white, starburst-like crystal aggregates embedded in a dark grey or black background matrix. Primarily found in China, particularly in Yonghe, Liuyang, Hunan Province, as well as locations in Japan, Canada, and the United States.
