Product Description for 12x10mm Oval Golden Prehnite-P14V000004
Prehnite is a pale yellowish to light green stone, sometimes even resembling jade, but prehnite often displays a unique glow or sheen. It was named after its discoverer, Hendrik Van Prehn, a Dutchman who brought prehnite from Africa to Europe in the late 1700s. Prehnite ranks a 6 to 6.5 on Mohs' hardness scale and primary sources include Australia, Scotland, and South Africa (Kalahari).
