Beautiful glassy gemmy pale yellow cubic crystals of fluorite to 1.3 cm on edge set perfectly up on matrix. This is in excellent condition.Fluorite from the May Quarry in Fort Wayne, Indiana occurs in limestone of Silurian age that was quarried for crushed stone and construction materials. During quarry operations small cavities in the limestone produced crystals of fluorite along with calcite and other secondary minerals. Most of the best specimens, including this one, were collected in the early 1970's.
