Physical properties
Hardness: 3-4 on the Mohs scale for the limestone matrix; Color: Dark gray to black with white, grayish, or yellowish flower-like crystal clusters; Luster: Dull to vitreous; Crystal structure: Orthorhombic (for celestine inclusions) or monoclinic/amorphous matrix.
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.
