Septarian tumbled stone

❗️ I intuitively select each piece when you purchase one or more

Septarian is a truly unique mineral formation that looks like cracked earth frozen in stone. Each piece features bold patterns of yellow Calcite, brown Aragonite, and grey limestone, all divided by natural, angular lines that formed as the stone dried and fractured millions of years ago.

These nodules started out as mud balls on ancient sea floors. As they hardened, internal cracks formed and later filled with minerals, creating the distinctive web-like patterns you see today. Most Septarian comes from places like Madagascar, where conditions were just right for this process to unfold.

With its mix of color, texture, and geologic history, Septarian is both eye-catching and fascinating. It’s a conversation piece that shows off nature’s ability to turn something as simple as mud into something truly remarkable.
