For centuries the mysterious moonstone has captivated the imagination with its unique and scintillating play of light. The use of Moonstone in fine jewelry dates back to ancient Greek and Roman civilizations who believed this iridescent stone to be gifts from their lunar gods. Ancient Hindu mythology held that Moonstone was comprised of solidified moon beams. During the Art Nouveau period in the late 1800's early 1900's, Moonstone was prominently featured in fine jewelry and art work such as the designs of French goldsmith Rene Lalique.
In contemporary India, Moonstones are regarded as 'dream stones' which are said to bring the wearer beautiful visions at night. Women in Arabic countries often wear Moonstones a symbol of fertility.
When you look at a Moonstone, it's easy to see why ancient civilizations believed it came from the moon. However, the more scientific explanation is a phenomenon called adularescence. Moonstone is composed of two feldspar species, orthoclase and albite. When the mineral is formed, the intergrowth of orthoclase and albite separates into stacked, alternating layers. As light falls between these thin, flat layers, it scatters in many directions producing the vibrant and enchanting effect which makes Moonstone so unique.
Though lovely Pearl and Alexandrite are also counted as the birthstones of June, Moonstone is my personal favorite June gem.
