Graptolite argillite round stone necklace, silver chain

Symbology

Graptolite argillite is a stone unique to Estonia, found nowhere else in the world in this quality. It is formed from the compressed fossils of graptolites, colonial marine organisms that lived 450 million years ago during the Ordovician period. Wearing it is a connection to a specific geology, a piece of Estonian prehistory made wearable. The stone is dark, matte and substantial, with a quiet authority that comes from genuine antiquity.
