Description

From the seller
Vivianite is renowned for its unusual and dramatic color transformation. As the mineral is exposed to light and oxygen, iron within the crystal structure gradually oxidizes, causing the crystals to darken through shades of blue-green and blue before eventually becoming deep blue-black to nearly black.
