These lovely stones were marked "prynite" which I've never heard of. Looking at them closely they appear to be natural stones with all their little fairy holes and inclusions. So I think they must be Prehnite. They have large irregular facets along the planes of the irregular crystals and the stones are quite thin, so this necklace has a lot of volume without much weight. Melody associates Prehnite with Libra and says it is a stone for dreaming and remembering. Simmons says it links the heart with the will. Ahsian calls it a gentle nurturing stone. The color is a very pretty soft green interspersed with stacks of creamy Chinese keshi pearls. Wouldn't it look lovely with your winter white dress or sweater? Perhaps the stones would assist in forming quiet, heart-centered connections in the midst of the holiday tumult.
