Moonstone- Inner growth and strength
Moonstone is a sodium potassium aluminum silicate of the feldspar group that displays a pearly and opalescent schiller. An alternative name for moonstone is hecatolite. The name moonstone derives from the stone’s characteristic visual effect, called adularescence (or schiller), which produces a milky, bluish interior light. This effect is caused by light diffraction through alternating layers of orthoclase and albite within the stone. The diffracted light varies from white to blue, depending on the thinness of the albite layers. More technically, this micro-structure consists of regular exsolution layers (lamellae) of different alkali feldspars (orthoclase and sodium-rich plagioclase).
