Information about Variscite

Variscite is a vibrant phosphate mineral known for its striking green to bluish-green color, often accompanied by white or darker vein-like patterns. Fine specimens may exhibit a subtle radiance due to their translucency.

 


Uses and History

Variscite is primarily used as a gemstone and ornamental material. Its striking colors and patterns make it popular for cabochons, beads, and decorative objects.

It is sometimes marketed as a replacement for Turquoise, but can also be missold as Turquoise – keep an eye out for that! It can be difficult to tell the difference.

A member of the variscite group, including

  • Mansfieldite – AlAsO4 · 2H2O
  • Scorodite – Fe3+AsO4 · 2H2O
  • Strengite – FePO4 · 2H2O
  • Variscite – AlPO4 · 2H2O
  • Yanomamite – InAsO4 · 2H2O

 

Variscite was first described in 1837 and named after the Variscia region, the historical name for Vogtland in Germany, where it was initially discovered.

The mineral has been used in ornamental carvings and jewellery for centuries, especially by Native American cultures in the southwestern United States. Notable deposits have also been found in Utah, Australia, and Brazil.

Hazards and Warnings

Easily confused with turquoise – I suppose this should be a financial warning.

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.
