Prehnite (South Africa) 10mm Round Beads, 16 inch Strands
Pale Green With Black Inclusions, Very Cool!
Prehnite is a pale yellow-green stone made primarily of calcium and aluminum.
Some forms have iron in them as well, which causes a darker orange-yellow colour, but the majority are quite pale and milky, not at all see-through.
The first recorded description of prehnite is from 1788, where Colonel Hendrick von Prehn discovered it in Cape Province in South Africa.
It was named after von Prehn, who was the commander of the Dutch military forces in South Africa, and who was quick to introduce Prehnite into South Africa’s booming trade in gemstones
