Prehnite was officially named in 1788 after a Dutch colonel named Hendrik von (or van) Prehn. Prehn--a naturalist and mineral collector--was given credit for discovering the stone in 1774, at the Cape of Good Hope in modern South Africa.

This stone has been given a number of other names over the years, including adelite, chiltonite, chrysolite of sage, coupholite, Karoo stone, grape jade and more.
