Historical Lore:
Black tourmaline, also known as schorl, is a boron silicate mineral found in regions including Brazil, Africa, and the United States. It has been known since ancient times, with early uses recorded in Sri Lanka where tourmaline crystals were traded and studied. In the 18th century, Dutch traders brought tourmaline to Europe, where it became known for its ability to attract ash when heated due to its pyroelectric properties. Historically, it has been valued primarily as a mineral specimen and in decorative use rather than widespread use in ancient jewellery compared to other gemstones.
