While this piece may contain more blue-green ajoite than sky-blue shattuckite, the shattuckite shows much better crystallization, apparently having formed on top of the ajoite in cavities within the host rock. The shattuckite has a radial growth pattern of acicular crystals, and a loupe shows that the natural crystal ends (undamaged surfaces) have a relatively deep blue, while the sides of the sprays appear much lighter blue in color.
