A vivianite crystal embedded in rock displays varying shades of green.
An eye-level close up view of a vivianite crystal embedded into the top of a brown rock placed on a black surface. The crystal resembles a group of straight sticks varying in size tied tightly together. There is a segment of the crystal that is extending at a diagonal angle from the top left quadrant of the image to the right side of the image, and a segment of the crystal behind it extending up toward the top of the image at a slight diagonal angle to the left. The crystal is dark green, on the right end of the front of the crystal and on the right side of the crystal behind it, the crystal appears to be a much lighter shade of green as light is shining through it. The light shining directly onto the crystal is being projected by the crystal onto the black wall behind it, around the sides of the crystal on the wall a light shaped like the crystal can be seen.
