Appearance, Uses and History
Olivine is a gorgeous green mineral – Peridot is the gemstone quality variant of Olivine.
Olivine has some interesting properties which give it a number of industrial uses. It has good heat resistance, so in some cases it is used for sand casting, or in blast furnaces.
One of its most interesting potential uses is in the potential removal of atmospheric CO2, as it weathers completely within a few years.
Peridot, however, is gemstone quality – it is used as a jewellery stone – often cut en cabochon or as faceted stones.
Australia, Brazil, China, Egypt, Mexico, Myanmar, Norway, Pakistan, Saudi Arabia, Spain, Sri Lanka, Tanzania, and the USA. Also occurs somewhere in space!

Hazards and Warnings
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.
