About Pudding Stone

Pudding Stone is a striking conglomerate rock native to parts of Michigan, most famously found in the glacial deposits of the Upper Peninsula and the Saint Joseph Island region. Its name comes from its resemblance to a traditional British boiled pudding—white “matrix” studded with colorful “ingredients.”

This unique stone is composed primarily of white quartzite or chert cemented together with a mixture of jasper, hematite, and other pebbles in shades of red, brown, gray, and black. The contrasting clasts were naturally fused together by ancient geological processes more than a billion years ago, creating a vivid, polished appearance that makes each piece entirely one-of-a-kind.

Pudding Stone was transported into Michigan by glaciers during the Ice Age, where it can still be found scattered in gravel pits, riverbeds, and along shorelines. It is prized by collectors and lapidary artists for its beauty, durability, and connection to the region’s deep geological history. Polished specimens reveal the colorful pebble inclusions in stunning detail—true natural art formed over eons.
