, the first mineral ever named after a person, was named after its Dutch discoverer, Colonel Hendrik von Prehn in South Africa in 1788. It was also the very first mineral to be named and described from South Africa, long before South Africa became known as an important source for gems.
A silicate mineral made up of calcium and aluminium, Prehnite is usually light green, with a whitish hue or yellowish tinge, not commonly found in deep green. It often appear cloudy or velvety, and rarely fully transparent. The stones may also contain colors zones of lighter and darker green.
Found naturally, not treated with heat or artificially enhanced, it was fairly uncommon until recent deposits of the mineral were discovered in Africa, making this gemstone more available and popular. Since it is very sensitive to heat and chips easily, so the jeweler must be very careful when cutting. Stones displaying the cat’s–eye effect have been discovered, but it’s very rare.
You’ll most often see it cut into cabochons. Here are some of our CED original jewels in Prehnite.
