Prehnite is an inosilicate of calcium and aluminium. It most often forms as stalactite or botryoidal aggregates, with only just the crests of small crystals showing any faces, which are almost always curved or composite. Prehnite is brittle with an uneven fracture and a vitreous to pearly luster. Its hardness is 6-6.5, In April 2000, rare orange prehnite was discovered in the Kalahari Manganese Fields, South Africa. Prehnite is mostly translucent, and rarely transparent.

Measurements are as accurate as possible, though be aware measuring precise dimensions can be difficult from irregular shaped items. Whilst we portray colours as close to life-like as we can, colours will vary if taken in sunlight, indoors, from monitor to monitor and device to device.
