This thumbnail piece consists of a cluster of small, scalene "dogtooth" Calcites. These Calcites are in excellent condition - only one shows slight damage at its tip - and reach 1.1" (2.8 cm) in length. All have very good trigonal form and contain included layers of tiny marcasite crystals- a few of the crystals are coated by layers of marcasite that show red and green colors and a metallic luster. The rest show the gray color and pearly luster of the calcite. There is no host rock, and the piece is affixed inside a plastic thumbnail box.
