Round septaria from Madagascar on black base
PUMI2093
Medium spherical Septaria from Madagascar The nodules of Septaria were initially formed around a core of organic matters (plant fragments, or dead animal corpse). By digging in a clay soil, we find a big oval pebble, and after polishing we highlig ht the extraordinary combination of craks filled with black crystal and the beige to dark brown of the nodule's body.
