Pyromorphite Crystal Mineral Specimen

Pyromorphite

HISTORY, NAME, LOCALITIES: Pyromorphite, pronounced pie-row-MORF-ite, was first described in 1748, but not formally named until 1813.  Its name is derived from the Greek words pyr, meaning ‘fire,” and morphe, or “form,” alluding to the manner in which melted pyromorphite globules assume a crystalline shape upon cooling.  Notable collecting localities are located in China, Germany, England, Russia, Australia, France, Zambia, and the United States (Idaho, Colorado).

MINERALOGY, PROPERTIES, OCCURRENCE: Pyromorphite [lead chlorophosphate, Pb5(PO4)3Cl] crystallizes in the hexagonal system in prismatic or barrel-shaped forms, often with diagnostic, cavernous or pitted terminations.  It is transparent to translucent, has a lime-green color, a Mohs hardness of 3.5-4.0, a resinous luster, and a high specific gravity of 6.5-7.1.  Pyromorphite is a secondary mineral that forms in the oxidized zones of lead deposits and is usually associated with such minerals as wulfenite, anglesite, and cerussite.

METAPHYSICAL PROPERTIES, LORE, USES: Metaphysical practitioners believe that pyromorphite refreshes one’s attitude and increases personal power by attracting material assets and energy.  Because of its great density, pyromorphite has a very high index of refraction and can make brilliant gems.  But because of its brittleness it is difficult to cut and is only occasionally faceted into collectors’ gems.  Pyromorphite was formerly an ore of lead.

COLLECTORS’ INFORMATION:  Pyromorphite is collected for its unusual chemistry, pleasing lime-green color, and hexagonal crystal shapes that often have distinctive, cavernous or pitted terminations.
