Also known as "pencil ore", these crystallized Hematite sections from the Hodbarrow Mine in England were once part of larger botryoidal structures which fractured and recrystallized naturally. The unusual event created one of the most wonderful series of curved growth hillocks to ever occur. The "point" of the specimen represents the section closest to the core of the original bubble of Hematite that later separated. The outer edge still shows the bubbly crystallization of the original formation. These were collected prior to the 1930s.
