STRIPED FLINT FOR SALE

Striped flint from Poland—renowned for its flowing bands of light and dark brown hues—is a rare, silica-rich flint formed as Jurassic-aged concretions within limestone nearly 160 million years ago. Mined near Sandomierz, Ostrowiec Świętokrzyski, and Iłża, this beautifully patterned material has been prized since Neolithic times, when it was worked into tools, and today its striking natural banding makes it highly sought after for jewelry and polished display pieces.
