The moonstone is an intimate combination of orthoclase and albite in an arrangement of thin layers to which it owes its beautiful blue bloom and its lovely sheen. This mineral has been available in the Kangayam district of Tamil Nadu in South India and also in the famous gem-gravels around Ratnapura in the south-western Sri Lanka.
