The Deluxe Hardness Pick Set is a tool for Mineral Identification, including a set of Hardness Points for performing a 'scratch test' on an unknown mineral to determine its Hardness under the Mohs scale. This deluxe kit includes two other mineral identification tests - a Streak Plate for determining an unknown mineral's inherent Color, and a Magnet for testing for minerals such as Magnetite, Pyrrhotite, and Nickel-Iron Meteorites. All of this comes packaged in a hard plastic case.
