What is the date and discovery of tourmaline?

Tourmaline has been known since ancient times, with its discovery dating back to at least the 1500s when it was first described in Europe. However, it wasn't until the late 18th century that it was identified as a distinct mineral group. The name "tourmaline" is derived from the Sinhalese Word "turmali," which refers to various gemstones found in Sri Lanka. Its unique properties and wide range of colors have made it a popular gemstone in jewelry throughout history.
