Moonstone is the popular name used for gem-quality feldspar that exhibits the phenomenon of adularescence. When light falls on the gemstone, it scatters in many directions, producing adularescence. This beautiful and intriguing adularescence that gives the gemstone’s surface a glowing appearance is what makes the moonstone so popular.

The name “Moonstone” was given because its appearance resembles the glow of the moon through a thin cloud cover. In fact, the most powerful time to wear the gemstone is during a full moon.

Sri Lanka is the world's most important source of fine-quality moonstone. Moonstone is also produced in significant quantities in Brazil, Myanmar and India.

The moonstone is the birthstone of June and is known for bringing good fortune. It enhances intuition, promotes fertility and brings success in love as well as business matters. Moonstone is a very personal stone. It is a reflection of the person who owns it. It does not add or detract, only shows how it is. This is why the moonstone is said to perceive that which "is". Moonstone is an excellent stone to use in meditation to understand oneself. It’s also a particularly good gemstone for women as women’s fertility cycles connect with the waxing and waning of the moon.
