Chalcedony

Chalcedony is a cryptocrystalline form of silica that comes in a wide range of colors, but mostly commonly found in white to grey, greyish-blue, and shades of brown. Dendritic varieties of this beautiful gemstone are naturally formed with intricate, branchlike patterns within the stone that are sometimes reminiscent of a nebula. Chalcedony is said to be a nurturing stone that promotes emotional and spiritual harmony.
