A #Neolithic rock crystal arrowhead found in Neuchâtel, Switzerland, dating ca. 3500 BC. The raw material was not available in the immediate area, but came from the Alps. Rock crystal has been mined in the Swiss Alps since the early Mesolithic; it is a particularly hard material, making it ideal for tools such as scrapers or perforators. It was widely used in the Alpine region for the manufacture of stone tools between the Mesolithic and the Bronze Age. 🧵 1/2
