BANDED FLINT 
Natural fragment

Essex

An interesting and attractive piece of natural flint that resembles fossil wood.

The process that created these bands in flint is not fully understood. It is thought by some that they could have been caused by the ‘Liesegang ring’ phenomenon - a complex chemical process that causes rhythmic banding of insoluble chemicals, in this case the rhythmic precipitation of silica (named after its discoverer, the 20th century German chemist Raphael Eduard Liesegang).
