The minerals that can form into small teardrop formations are known as teardrop minerals or botryoidal minerals. Botryoidal minerals are characterized by their rounded, globular shapes resembling a bunch of grapes or small teardrops. This formation occurs when the mineral precipitates out of a solution in a concentric or radial pattern, creating the distinctive teardrop shape. Examples of minerals that commonly form botryoidal shapes include malachite, chalcedony, and hematite.
