Moonstone：The most iconic gem variety in the feldspar family
Moonstone: The Lover’s Stone and June Birthstone
Moonstone is the most iconic gem variety in the feldspar family, formed by alternating layers of orthoclase and albite that produce the optical phenomenon known as adularescence—an ethereal blue sheen that looks like moonlight floating on water. Revered as the “Lover’s Stone” in the international jewelry market, it is also one of June’s birthstones, with the finest glassy blue specimens coming from Sri Lanka.
