Prehnite is a calcium aluminum silicate, the color is usually yellow/green to pale green but can be yellow, white, or colorless.
Prehnite: Meanings, Benefits and Properties
The frequency of Prehnite connects to the solar plexus and heart chakras.
Prehnite allows one to use one’s willpower with a heart-centered awareness so that one’s actions are in alignment with one’s heart and thus one acts with love, kindness, and compassion.
Prehnite can open one’s heart center to receive guidance from one’s soul and higher dimensional beings. Its energy is nurturing and thus helps one to become calm and centered, bringing an inner peace that can aid with issues of nervousness and worry.
The energy of Prehnite can help to purify one’s physical body of toxins and urinary infections.

Geological Properties
Prehnite crystallizes in the orthorhombic crystal system, and most often forms as stalactitic or botryoidal aggregates, with only just the crests of small crystals showing any faces, which are almost always curved or composite.
Very rarely it will form distinct, well-individualized crystals showing a square-like cross-section, including those found at the Jeffrey Mine in Asbestos, Quebec, Canada.
Though not a zeolite, prehnite is found associated with minerals such as datolite, calcite, apophyllite, stilbite, laumontite, and heulandite in veins and cavities of basaltic rocks, sometimes in granites, syenites, or gneisses. It is an indicator mineral of the prehnite-pumpellyite metamorphic facies.
Prehnite is brittle with an uneven fracture and a vitreous to pearly luster. Its hardness is 6-6.5, its specific gravity is 2.80-2.90 and its color varies from light green to yellow, but also colorless, blue, pink, or white.
In April 2000, rare orange prehnite was discovered in the Kalahari Manganese Fields, South Africa. Prehnite is mostly translucent and rarely transparent.
Extensive deposits of gem-quality prehnite occur in the basalt tableland surrounding Wave Hill Station in the central Northern Territory, of Australia.
History
It was first described in 1788 as an occurrence in the Karoo dolerites of Cradock, Eastern Cape Province, South Africa. It was named for Colonel Hendrik Von Prehn (1733-1785), commander of the military forces of the Dutch colony at the Cape of Good Hope from 1768 to 1780.
