From the Henry Mountains of Utah, the mineral Septarian formed in an ancient sea floor some 50-70 million years ago as sediment collected around sea life as they decomposed. Calcium carbonate from the shells of these creatures began to take a new form over time, creating calcite crystals and bands of aragonite. The gold-colored crystals inside are calcite, the brown is aragonite, and the outer surface is composed of limestone.
After collecting fossils as a hobby for many years growing up, Dave Douglass opened Dave's Down to Earth Rock Shop in 1970 at the age of 20 (with the help of his parents) at 1312 Chicago Avenue in Evanston, Illinois. The shop contained minerals and fossils, mostly self-collected by the Douglass family.
