Pyromorphite is a mineral that occurs in a range of colours including green, yellow, red and brown. The phonetic transcription of the word ‘pyromorphite’ is /ˌpaɪrəʊˈmɔːfaɪt/. The spelling of the word is based on the Greek words ‘pur’ meaning fire and ‘morphē’ meaning shape. This is due to the mineral’s ability to turn red upon heating. Pyromorphite is frequently used in the manufacturing of ceramics and in some battery components. Interestingly, pyromorphite is also a certified gemstone, although it is less commonly used in jewelry making.
Pyromorphite is a mineral with the chemical formula Pb5(PO4)3Cl, belonging to the apatite group. It is commonly recognized for its unique crystal structure and vivid green color, often seen in small prismatic or barrel-shaped crystals. The name "pyromorphite" is derived from the Greek words "pyr" meaning fire and "morphos" meaning form, alluding to its early discovery in brown oxide-rich lead ores that could turn green when heated.
Pyromorphite is primarily composed of lead and phosphate, with small amounts of chlorine incorporated into its structure. It occurs in the oxidized zones of lead ores, frequently associated with galena (lead sulfide) and cerussite (lead carbonate). This mineral usually forms as a secondary mineral, precipitating from mineral-rich solutions in fractures and cavities, or as a pseudomorph after other lead-bearing minerals.
Pyromorphite is valued for both its aesthetic and scientific significance. Its vibrant green color, ranging from pale to deep green, makes it a sought-after gemstone among collectors. It is also renowned for its ability to form exquisite combinations with other minerals, such as quartz or barite. Moreover, pyromorphite is of great interest to scientists due to its environmental impact. With its lead content, pyromorphite can sequester lead from the environment, potentially serving as a remediation mineral in areas contaminated with lead.
In conclusion, pyromorphite is a captivating mineral appreciated for its rich green color, crystal habits, and its potential as an environmental resource.
A native phosphate of lead, a mineral of a green, yellow, or grey colour.

The word "pyromorphite" has its roots in the Greek language. It is derived from two Greek words:
1. "pyr" (πῦρ), which means "fire".
2. "morphē" (μορφή), which means "form" or "shape".
When combined, these words form "pyromorphite", which describes a mineral known for its crystal forms and vibrant color, often resembling a flame or fire.
