Moonstone is a pearly and opalescent variety of Microcline, it is common to find it in large masses, but not crystallized.
This is a big single crystal. You will only see the Moonstone effect on one side, but this one got very good intensity of green/blue color seen without extra light.
Actually you will see a minor Moonstone effect also on one of the other sides, but only if you add extra strong light.
