Formed by ancient microbial activity, this Bolivian Stromatolite Sphere is among the most fascinating fossil materials on Earth — layered limestone built up by cyanobacteria from the Cretaceous period, preserved in stone. This 2.38 inch, 0.68 pound hand-carved and polished sphere reveals that signature concentric banding in warm browns and greys, a unique cross-section of natural history you can hold in your hand. Because it is hand-carved, it is not perfectly round — adding to the organic character and authenticity that makes each piece genuinely one of a kind. Smooth, weighty, and tactile, it reads as décor first and conversation piece always.
