Physical properties
Hardness: 3-4 (flower) to 3-4.5 (matrix). Color: Black or dark grey matrix with white or light-colored flower-like crystals. Luster: Vitreous to dull.
Formation & geological history
Formed during the Permian period in shallow marine environments. The 'flowers' are formed by the replacement of minerals like celestite, calcite, or strontianite in a limestone or shale matrix.
Uses & applications
Primarily used as a decorative stone, carved into ornaments, cabochons, and beads. Highly prized by collectors for its unique floral patterns.
Geological facts
Named for its resemblance to chrysanthemum flowers. It is the official symbol of the Chinese Imperial family and is associated with longevity and good fortune.
Field identification & locations
Identified by its distinctive white, radiating, flower-like crystal clusters on a dark background. Commonly found in China, Japan, Canada, and the USA.
