Hertfordshire Puddingstone brooch c1940
This is a very unusual brooch set with a Hertfordshire Puddingstone and set in silver. Hertfordshire Puddingstone is a conglomerate of rounded flint pebbles in a matrix of fine pale sand all cemented together (basically a ‘fossil beach’). As the pebbles, the sand and the cementing material are all silica the rock is very hard and breaks evenly across pebbles and sandy matrix. The story of Hertfordshire Puddingstone is also the story of climate changes over the last 80 million years ranging between extremes of hot and cold.
