Natural Pale Green Prehnite Classic Beaded Necklace, Genuine Gemstone

Natural Pale Green Prehnite Classic Beaded Necklace, Genuine Gemstone Prehnite is a newly-found semi-precious stone. It was first described in 1788 and named for Colonel Hendrik Von Prehn (1733–1785), commander of the military forces of the Dutch colony at the Cape of Good Hope. The beauty of this stone is its semi-transparent colour, which makes it looks like high-quality jade. An inosilicate of calcium and aluminum, prehnite forms crystals of a pearly green or yellow luster. Particularly beautiful specimens are used to carve pendants or rings. 10.5 mm pale green prehnite round beads 2 mm transparent glass spacer Total length is about 18", screw clasp
