- Prehnite is a translucent to transparent gem-quality hydrated calcium aluminum silicate. It was the first mineral to be named after an individual, and it was also the first mineral to be described from South Africa. Named in 1788 by Abraham Gottlieb Werner in honor of the Dutch Colonel, Hendrik von/van Prehn, who is credited with discovering the mineral in 1774 at the Cape of Good Hope in South Africa.
- Prehnite forms in both odd and distinct formation habits. It 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.
- Chemical Formula: Ca2Al2Si3O12(OH); Color: Light green, dark green, mint-green, yellowish-green, brownish-green, and bluish-green. Rarely brown, yellow, orange, pink, gray, white, or colorless. Hardness: 6 - 6.5; Specific Gravity: 2.8 - 3.0.
