Striped flint
Striped flint – natural stone
Striped flint is a mineral that consists of 95% chalcedony, quartz, and a small amount of calcium carbonate and opal. Striped flint mineral is very unique as it is found only in one place in the world – Poland. Due to its origin and unique appearance, it is often called the “Polish gemstone”. In reality, striped flint can be found all over the world, but they are not gem-quality stones. It is only the Polish striped flint that can be used as a gemstone due to its high hardness, beautiful stripes on the surface, and its ability to be polished to a high luster. The hardness of banded flint on the Mohs scale is 5.5-7, while the density is 2.58-2.91. Its characteristic features are high lustre, cleavage and shell fracture. It should be emphasized that there are no two identical flats or glazes, each one is unique and original because the bands are arranged differently each time.

Striped flint – color
Striped flint occurs in a brown color – light or dark, but sometimes it can be found in shades of yellow. Its main characteristic, which gives it its name, is the presence of unique stripes and streaks on its surface. Dark and light layers can be observed in the structure of striped flint, which creates the unusual patterns. The variability of micropores is responsible for the stripes – darker stones have fewer micropores, while lighter have a larger number. The color of flint is determined by the presence of chalcedony, quartz and calcium carbonate in its structure. The price of striped flint is mainly influenced by its quality and the pattern on its surface – the stripes should be clear and densely arranged.
Striped flint – application
Since ancient times, flint has been used to make everyday items such as axes, various tools, and ornaments. Natural flint was also often used to decorate figurines, vases or amulets. Now however, because of its original appearance, it is most often used in jewelry. Interestingly, the use of this mineral in jewelry was initiated by the Polish goldsmith from Sandomierz, Cezary Łutowicz, in 1972. Since then you can find striped flint in rings, necklaces and earrings. In our online store you can find striped flint cabochons and flats.
