SEPTARIA open sphere from Madagascar
PUMI2749
This SEPTARIA sphere was formed from clay-rich sediments containing organic matter, often originating from decaying plants. Over time, pressure and compaction caused internal cracks to appear. These cavities gradually filled with crystallized minerals—typically calcite— capturing the slow transformation from organic deposit to mineral structure.
On this specimen, the outer surface shows a dark clay-brown colour, crossed by almost graphic black veins. Inside, the crystallization remains dense and dark.
A natural curiosity born from the slow alchemy of living matter turning to stone.
