Moonstone is a sodium potassium aluminium silicate of the feldspar group that displays a pearly and opalescent schiller. An alternative name is hecatolite.
Moonstone as it is named is connected to the moon and is the stone of new beginnings. Moonstone is a very reflective stone, reminding us about the waxing and waning of the moon, just like the cycles we go through in life.
