Pyrite Included Serpentine (Jade) Green calcite This mineral is usually foundThis variety of serpentine, often called new jade, displays fine inclusions of pyrite that add a metallic shimmer to its soft green surface. Serpentine is a magnesium silicate mineral formed through the alteration of ultramafic rocks, while pyrite (FeS) crystallizes as golden flecks within the stone. Together they create a striking contrast of earthy green and metallic gold, most commonly found in deposits from China and South Africa. This item is 2 x
