Jonesite is a mineral belonging to the arsenate mineral group, specifically the apatite supergroup. It was first discovered in 1926 in the Tsumeb mine in Namibia. Jonesite is named after L. J. Spencer Jones, an Australian mineral collector. It is a relatively rare mineral and is typically found in hydrothermal deposits associated with other minerals such as olivenite, mimetite, and cerussite.
Jonesite has an orthorhombic crystal structure and its chemical composition is primarily composed of copper, arsenic, and oxygen, with trace amounts of other elements. It has a distinct yellowish-green to green color that can vary in intensity depending on impurities present. The mineral is translucent to opaque and has a vitreous to dull luster. It possesses a Mohs hardness of 3.5 to 4, which means it can be scratched by a knife but not by a fingernail.
While jonesite is not widely known for its commercial uses, its crystal form and vibrant color make it a sought-after mineral by collectors and enthusiasts. Due to its rarity, specimens of jonesite can be valuable and highly prized. Its distinctive green hue and unique crystal habit make it a visually appealing addition to mineral collections.
In summary, jonesite is a green arsenate mineral that is relatively rare and valued by collectors for its unique crystal form and color.
