4.3" Variscite In Magnesium Aluminum Phosphate - Australia
This is a polished slab of Variscite collected near the Woodlands Cattle Station in the Goscoyne region of Western Australia. One side is highly polished and it comes with an acrylic display stand.
Variscite (which is closely related to turquoise) is a secondary mineral formed by direct deposition from phosphate-bearing water that has reacted with aluminium-rich rocks in a near-surface environment. It occurs as fine-grained masses in nodules, cavity fillings, and crusts. Variscite often contains white veins of the calcium aluminium phosphate mineral crandallite. It is sometimes confused with turquoise; however, variscite is usually greener in color.
