Sunstone and moonstone are both feldspar, named for the two lights of the sky, and both take their character from what happens inside the crystal rather than on its surface. Here that character is colour: a clear reddish orange that brightens facet by facet whenever it is turned. Look at it from the side, where the lower facets throw back a stronger red than the top.
