Description: BEAUTIFULRARE Natural PREHNITE crystal cluster from Mibladen, Morocco #3Prehnite is a variation of asilicate mineral that rarely forms individual crystals. It is more commonlyfound as stalactites and botryoidal clusters. It is comprised of calciumand aluminum and is most commonly green but has been discovered in shades of yellow,blue, pink, orange, white, and even colorless. It was first discovered in 1788in Cradock, South Africa by a Cutch mineralogist by the name Hendrik von Prehn.This is where its name is derived from. Prehnite forms in the veins andcavities of volcanic rock, often basalts, but also occurring in granites. Thisstone is usually translucent, yet rarely transparent or clear. Cat's eyeformations within prehnite are possible, but rare. It is a rather singulargemstone, with no near relatives, although many are visually similar enough tocause confusion.Prehnite can be found inSouth Africa, Australia, Canada, Mali, Morocco, Namibia and a variety of smalldeposits across Europe and the United States. A distinctive pink variety isfound among the basalt deposits in the US state of Michigan, on the KeweenawPeninsula, containing copper and chlorite inclusions.Chemical Formula: Ca₂Al₂Si₃O₁₂ (OH) As per Wikepedia: Prehnite is brittle with an unevenfracture and a vitreous to pearly luster. Its hardness is 6.5, its specific gravity is 2.80–2.95 and its color varies from light green toyellow, but also colorless, blue, pink or white. In April 2000, rareorange prehnite was discovered in the Kalahari Manganese Fields, South Africa. Prehnite is mostly translucent,and rarely transparent.SPECS: Weight: 118g Length: About 3.5" Width: About 1.75" Depth: About 1"
