Alexandrite, Moonstone and Pearl are the birthstones for June


  • Green in sunlight, red in lamplight, Alexandrite is the rare color-change variety of the mineral chrysoberyl. Gem collectors often describe
    alexandrite's dramatic color change as “emerald by day, ruby by night”

  • Alexandrite is named after Alexander II, heir apparent to the Russian throne. It caught the country’s attention because its red and green colors reflected the national military colors of imperial Russia

  • Originally discovered in Russia’s Ural Mountains in the 1830’s, its currently mined in Sri Lanka, East Africa, and Brazil


  • Moonstone is a variety of the feldspar-group mineral orthoclase. Its composed of two feldspar minerals, orthoclase, and albite. Moonstone’s unearthly glow is caused by light scattering between microscopic layers of feldspar

  • Adularescent moonstone was once called “adularia.” The name originated with a city in Switzerland, Mt. Adular (now St. Gotthard), that was one of the first sources of fine quality moonstone

  • According to Hindu mythology, moonstone is made of solidified moonbeams. Many other cultures also associate this gem with moonlight, and its easy to see why. Moonstone’s internal structure scatters the light that strikes it, creating a phenomenon known as adularescence. The visual effect is reminiscent of the full moon shining through a veil of thin, high clouds


  • Natural pearls form without human help of any kind. Within the shell of certain mollusks, the mantle tissue produces nacre that coats a microscopic irritant, eventually forming into a natural pearl. Cultured pearls are created as the result of the deliberate insertion of a bead or piece of tissue, that over time the mollusk coats with nacre

  • The most familiar colors of pearls are white and cream. Black, gray, and silver are also common, however the palette of pearl colors extends to every hue

  • In 1917, Pierre Cartier traded a double strand of natural pearls for a mansion on Fifth Avenue in New York City. The Cartier flagship store is still located in that Fifth Avenue mansion

  • People have coveted natural pearls as symbols of wealth and status for thousands of years. Members of royal families the wealthy citizens in Asia, Europe, and elsewhere treasured natural pearls and passed them from generation to generation

  • Your birthstone is personal and affordable to collect. Birthstone jewelry creates a cherished gifting experience
