Lime Green Prehnite (Semi-Precious gemstone) Necklace

A glistening lime green 17-inch necklace made up of small 3mm chips of Prehnite stone. It is strung with a complimentary green cord and has a silver tone barrel clasp. It is very secure. I believe this necklace came from Austria. N-190 Prehnite is a fairly strong crystal, quite resistant to pressures and scratching. It is composed of aluminum, calcium and silicon with a few specimens containing small trace of iron as well
