Introduction

Moonstones, with their ethereal glow and dreamy translucence, have been captivating the human imagination for centuries. They are named for their resemblance to the moon, and their unique visual effect, known as adularescence, is reminiscent of moonlight shimmering upon water. This article peels back the layers of this intriguing gemstone, delving into its origins, its role in various cultures, and the science behind its magical appearance.

The Origin of Moonstones

Moonstones are a type of feldspar, constituting about 60% of the earth’s crust. They are composed of two species - orthoclase and albite. When these minerals cool down after formation, they separate into alternating layers. When light falls between these thin, flat layers, it scatters in multiple directions, creating the effect of a soft, billowy glow that seems to roll across the surface of the stone when it is moved. This is the moonstone’s famed adularescence.

The Moonstone in History and Culture

Moonstones have been revered in various cultures for their mystical properties. They were used in jewelry by the ancient Romans who believed that the stone was formed from drops of moonlight. In India, moonstones are considered sacred and are traditionally given as a wedding gift.
