Physical properties
Hardness: 6.5-7 (Mohs), Color: Translucent grey to pink with cream/white opaque inclusions, Luster: Waxy to vitreous, Structure: Cryptocrystalline, Cleavage: None
Formation & geological history
Formed primarily in Madagascar within volcanic cavities where silica-rich groundwater deposited layers of chalcedony alongside opaque inclusions that resemble flowers.
Uses & applications
Metaphysical collecting, decorative ornaments, jewelry (cabochons), and meditation tools.
Geological facts
The 'flower' inclusions are actually opaque plume-like structures made of Chalcedony or occasionally Spherulites, which create a 3D floral effect within the stone.
Field identification & locations
Look for distinctive opaque, cream-colored bursts or 'blossoms' trapped within a semi-translucent chalcedony matrix. It is almost exclusively sourced from Madagascar.
