Physical properties
Hardness of 3-4 on the Mohs scale, dark gray to black matrix with white, grey, or greenish floral flower-like crystal patterns, vitreous to dull luster, cryptocrystalline to microcrystalline structure.
Formation & geological history
Formed in Permian-age seabed lime mud deposits approximately 250 to 300 million years ago, where hydrothermal fluids caused mineral crystallization in radial aggregates.
Uses & applications
Used primarily for ornamental carving, decorative polished pieces, display specimens, and in lapidary arts and jewelry.
Geological facts
The distinctive crystal clusters resemble blooming chrysanthemum flowers, hence the name. They are predominantly sourced from China and Japan.
Field identification & locations
Easily identified by its contrasting floral crystal inclusions embedded within a dark limestone or dolomite matrix. Common localities include Hunan Province, China.
