Description: | Jasper agate is a mixture of jasper (an opaque, waxy variety of chalcedony), and more translucent chalcedony. Chalcedony is microcrystalline (the crystals are too small to be seen without a microscope) quartz. Jasper agate can be found in the Cheviot Hills of Northumberland, with agate, usually in shades of pink and red, smoky quartz, amethyst and rock crystal. | License: | http://www.imagine.org.uk/about/copyright/ | Rights holder: | Tyne & Wear Museums | Subjects: | rocks and minerals natural world | Source: | Tyne and Wear Imagine | Identifier: | http://www.imagine.org.uk/details/index.... | Go to resource |
