The gemstone Prehnite was named for its discoverer, Colonel Hendrik von Prehn (1733-1785), a Dutch mineralogist and an early governor of the Cape of Good Hope colony.
Prehnite’s minty green hue offers an intriguing luster, ranging from shiny to pearlescent, and sometimes seems to glow in the sun.
Prehnite most often occurs as rounded or bubbly crystal masses, and commonly forms odd-shaped epimorphs after Anhydrite, Glauberite, and Laumontite. These epimorphs are remarkable for having hollow centers of a dissolved early-stage mineral. Elongated Prehnite formations are almost always rounded at the head and resemble fingers, and they are affectionately called “Prehnite Fingers” by collectors. A particularly desirable formation, known as a snakehead, describes an elongated Prehnite epimorph with a widened head.
Magical Crystal and Metaphysical Qualities of Prehnite
