Flint (or flintstone) is a hard, sedimentary cryptocrystalline, categorized as a variety of chalcedony. Flint is usually dark-grey, blue, black, or deep brown in color, and often has a glassy appearance. It occurs chiefly as nodules and masses in sedimentary rocks, such as chalks and limestone.
What is rare in this material is the internal layering. This type of flint, called banded flint, only occurred in the Jurassic limestone on Poland (160 million years ago). The irregular banding creates extremely picturesque internal structures of the mineral.
During the Neolith Period (5000-3500 years ago) flint was mined for the production of tools (axes, arrowheads, knives, etc.). These tools were exported as far as the Netherlands and the Black Sea. The ancient mines were only recently rediscovered in the twenty century, in the area of Ostrowiec Swietokrzyski.
