Nucleus of Honey-coloured silex, necropolis of Sant Julià de Ramis (Gironès), Neolithic, 4,200-3,500 BC. Archaeology Museum of Catalonia, Girona.
During the height of the Neolithic, extensive networks of raw-material exchange are documented, materials such as honey-coloured silex, possibly from Provence, variscite from Gavà and obsidian from the island of Lipari, near Sicily. Honey-coloured silex appeared in the Neolithic in the form of flakes, arrow heads and nuclei. Generally, this type of silex was cut by applying pressure and is found among grave goods.
