HERTFORDSHIRE PUDDINGSTONE
Small cut and polished slice
One of Britain’s most unusual rocks
A very small slice of this intriguing rock, polished on both sides.
Puddingstone was formed about 60 million years ago as layers of flint pebbles were laid down by the sea across Hertfordshire. When the sea retreated the pebbles were cemented together by quartz when the climate was hot, probably similar to the present day Kalahari Desert. The result was a layer of extremely hard rock called Hertfordshire Puddingstone.
Puddingstone was popular in Victorian times for jewellery and decorative objects.
