Eudialyte is a silicate mineral, which forms in alkaline igneous rocks. It is rarely found in crystal form, and is typically a granular formation within host rocks. It contains Calcium, Cerium, Sodium, Iron, Manganese, Zirconium, and Yttrium. The stone usually ranges from pink, red, and violet, to darker blacks and browns (sometimes with inclusions of Black Tourmaline. Eudialyte is named from the Greek term for "readily decomposable", which refers to its solubility in acid.
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.
