Green moonstone is not as well known as rainbow or blue moonstone as it doesn’t have the colour play, but it is still a beautiful stone It usually has a clear or slightly hazy appearance and a pale yellowish green colour, and when you look down at the stone you will see a light emanating from within, like a full moon. It is often cut with a high dome to accentuate this optical effect and frequently a star of light will be visible on the top of the dome.
