Flint, a variety of Chert, is a micro-crystalline, sedimentary rock of the silicate family and has a conchoidal fracture. The formation of flint is heavily believed to be strongly associated with the deposition of Chalk. Historically, flint has had many uses including being used as a way to start fires as well as being cut and sharpened to create weapons due to its hardness. Whilst flint can be found in a range of colours, this particular flint exhibits a monochromatic colour theme with a dark grey to black interior offset by a distinct white exterior. This flint was collected from South Devon, an area with a rich mining history. These specimens come provided in a card tray with an information label.
