Physical properties

Formation & geological history

Formed through the cooling and solidification of silica-rich volcanic fluids within igneous rock cavities. The flower-like plumes are formed by the inclusion of minerals—primarily Scolecite or varieties of Calcedony—that grow in radiating circular patterns.

Uses & applications

Primarily used in the jewelry and lapidary arts for cabochons, beads, and decorative carvings (like the heart shape shown). It is highly popular in the metaphysical and gemstone collecting community.

Geological facts

Flower Agate was relatively recently discovered in Madagascar (around 2017). It is unique because it features a '3D' effect where the 'flower' inclusions appear to float at different depths within the translucent chalcedony.

Field identification & locations

Identify in the field by looking for the distinct 'plumes' or 'blooms' embedded in translucent stone; unlike moss agate which has thin filaments, this has rounded, petal-like clusters. It is almost exclusively found in the Ambilobe region of Madagascar.
