Reserve Petrified Wood Spheres | In Select Sizes

These Curator's Choice Reserve Petrified Wood Spheres represent a premium selection primarily from Madagascar. These spheres form through a natural process where ancient trees, rapidly buried in sediment or volcanic ash, are preserved by mineral-rich groundwater over time. Silica and other minerals infiltrate and replace the wood’s organic cell structure, crystallizing into quartz, opal, or chalcedony. This transformation results in a stunning stone sphere that maintains the intricate details of the original wood, making each piece a unique specimen of geological and botanical history.

You will receive one premium sphere in the size range you select, similar to those pictured, each with its own unique pattern and coloration. Choose your preferred color tone in the drop-down and we’ll do our best to select a piece that matches your choice. Because each item is one-of-a-kind, preferences aren’t guaranteed—but we’ll always prioritize your selection when we pack your order.
