Almeidaite is a complex oxide of lead, zinc, manganese, and titanium (Menezes et al. 2015). The type (and currently only known) locality for almeidaite is an iron mining area. Collector-dealer Luis Menezes (1950-2014) noticed that these crystals looked different than hematite. When preliminary chemical data revealed its complex chemistry, a mineral species description was undertaken. Almeidaite is remarkable for its crystal size for a recent new species (IMA2013-020).

This is a section of a single crystal, 1.6 cm across, with minor chipping on its edges. The mineral typically shows an altered surface, much like shrinkage cracking on mud, which visually distinguishes these from the well known hematite crystals found nearby.
