Paralaurionite is a lead oxyhalide mineral with the chemical formula PbCl(OH). It forms transparent to white to pale colored crystals that are typically prismatic and exhibit a distinct cleavage, common in monoclinic systems. Crystals are often small but can display a glassy to resinous lustre, and translucency ranges from transparent to nearly opaque in larger specimens. Habits tend toward prismatic forms, sometimes elongated, with a compact to granular term when crystals are imperfect.

About Paralaurionite
Notable specimens come from the United States, Chile and Morocco, where paralaurionite occurs in oxidized lead-rich environments associated with halide-rich alteration zones. Collectors prize its pale color range and the ease with which its monoclinic prisms reveal themselves under magnification, making it a rewarding subject for display and study. Its relatively high specific gravity and distinct cleavage contribute to its character as a standout in oxidized lead assemblages, offering contrast when grouped with more common halides and oxides.
