Information about Linarite

Linarite is a strikingly vibrant mineral known for its deep azure-blue to indigo colour. It typically forms as prismatic or tabular crystals, often in radial aggregates or crusts on the surface of host rocks.

Linarite has a vitreous to silky luster and is transparent to translucent. Its intense colour and crystal habit make it a favourite among mineral collectors.

Uses and History

Due to its rarity, linarite has no significant industrial applications. However, it is highly valued by mineral collectors for its vivid colour and well-formed crystals. Geologists also study linarite for its role in the geochemical processes of oxidised lead-copper deposits.

Linarite was first described in 1822 and named in 1839 after its type locality in Linares, Spain.

The mineral has since been discovered in various locations worldwide, including well-known deposits in the United States, Germany, England, and Mexico.

Its association with other lead and copper minerals has made it an important indicator mineral in studying oxidation zones in mining regions.

Hazards and Warnings

Toxic mineral: contains lead.

Mineral collectors should wash their hands after handling specimens, to avoid any exposure to potential toxins.

Almost all rocks, minerals (and, frankly, almost all other substances on earth) can produce toxic dust when cutting, which can cause serious respiratory conditions including silicosis.

When cutting or polishing rocks, minerals, shells, etc, all work should be done wet to minimise the dust, and a suitable respirator or extraction system should be used.
