Description: | Smokey quartz is the brown-coloured variety of quartz. This semi precious gemstone is sometimes set in jewellery. The smokey colour is not always natural, and can be produced by treating clear quartz. Some of the finest examples of smokey quartz originate from Switzerland. Cairngorm (named after the range of Scottish Mountains) is a name that is sometimes applied to smokey quartz that is found in Scotland. | License: | http://www.imagine.org.uk/about/copyright/ | Rights holder: | Tyne & Wear Museums | Subjects: | beyond the North East rocks and minerals natural world | Source: | Tyne and Wear Imagine | Identifier: | http://www.imagine.org.uk/details/index.... | Go to resource |
