Physical properties

Hardness: 6.5-7 Mohs; Color: Translucent pink, grey, or white with opaque white/pink flower-like inclusions; Luster: Vitreous to waxy; Crystal structure: Trigonal/Microcrystalline; Cleavage: None; Specific Gravity: 2.60-2.65

Formation & geological history

Formed through the deposition of silica-rich groundwater in volcanic rock cavities. The flower-like plumes are caused by spherulitic inclusions, typically of chalcedony or other minerals like hematite or manganese, that grow in radiating patterns.

Uses & applications

Primarily used for lapidary work, jewelry making, decorative carvings, and as a popular specimen for crystal collectors and metaphysical practices.

Geological facts

Flower Agate is a relatively recent find in the geological world, first discovered in Madagascar around 2018. It is renowned for its unique 'blossom' patterns that look like 3D floral arrangements frozen in stone.

Field identification & locations

Identify by looking for translucent chalcedony hosting opaque, circular, or plume-like inclusions that resemble flower petals. It is found almost exclusively in Madagascar. To distinguish from similar stones, check for the distinct translucency versus the opacity of the flower patterns.
