Moonstone Beach ~ Catalina Island.
I was there at about age 12. Sure enough I found a little moonstone, approx the size of a pinto bean. Had to wade out about ten feet into the water to get it.
I recall I was the only one who did.

Moonstone is composed of two feldspar species, orthoclase and albite. The two species are intermingled. Then, as the newly formed mineral cools, the intergrowth of orthoclase and albite separates into stacked, alternating layers. When light falls between these thin, flat layers, it scatters in many directions producing the phenomenon called adularescence.
