SEPTARIAN TUMBLE

SeptarianThis fascinating Septarian Tumble is a window into ancient Earth history — a concretion formed on the seafloor approximately 50–70 million years ago, its distinctive cracked and filled interior revealing a beautiful natural mosaic of golden Calcite, brown Aragonite, and grey Limestone that makes each piece completely unique.Where It Is FoundSeptarian nodules are found in several locations worldwide, with major commercial sources in Madagascar (the primary source of most Septarian available in the crystal market), Utah, USA (where spectacular large nodules are found in the Cretaceous-age Bear River Formation), Morocco, and New Zealand. Madagascar and Utah produce the majority of the polished Septarian specimens available today.Mineral Class / GeologySeptarian is not a single mineral but a sedimentary concretion composed of multiple minerals — typically Calcite (yellow to golden, filling the cracks), Aragonite (brown, forming the outer shell and inner walls of the cracks), and L
