Half-Moon Septarian Geode
Polished Cretaceous concretion with calcite crystal void
A naturally formed septarian nodule, sliced and polished to reveal a striking interior of honey-toned calcite crystals bordered by dark aragonite veining. Two small fossil shell inclusions are visible within the matrix. Displayed on a fitted wood stand, the piece showcases nature's own geometry — sharp radiating fractures filled over millions of years.
