Hemimorphite comes in two forms, crystalline and a globular form. Forms similar to quartz with it's crystals and agate forms. Hemimorphite crystals are interesting because they have different types of terminations on each end of a single crystal. Of course one end is usually attached to the matrix and the termination is obscured. Hemimorphite is a basic hydrous zinc silicate. This specimen is the globular form once thought to be smithsonite. This specimen is from Wensnan Yunnan Provence, China.
