Identify Minerals with This Convenient Kit
This unique set contains three mineral tests in one box, plus the innovation of the hardness testing points. Unlike other tools that chip and break, the four double-ended picks in this set are made of durable ground metal and alloy points. The points can be resharpened easily with the included grinding stone. For ultimate convenience, the picks are stamped with the indicated hardness value, 2 through 9 on Mohs’ hardness scale, and are color-coded for quick identification. Packaged in one neatly arranged, compact wooden case, the set also includes a streak plate, glass plate, and instructions.
