Under proper conditions, pure minerals will develop into a crystal form characteristic of that mineral.
Crystal form is a valuable tool in the identification of minerals, but requires careful study. Perfect crystals are rare, but fragments and imperfect crystals will give basic information. This collection includes specimens that exhibit crystal forms from the six crystallographic systems.
Includes a study guide defining and explaining terminology of crystals. 15 crystal specimens, sizes vary with specimens available, in a compartmented tray.
