Opal, October's birthstone, is a crystalline form of silica classified as a mineraloid, rather than a mineral, because of the stone's amorphous nature. Opals are formed within the cracks of volcanic rock. Opal's optical density ranges from opaque to semi-transparent. Its internal structure, made up of varying amounts of water and spheres of silica, diffract light and create a myriad of colors including gorgeous reds and oranges, and breathtaking blues and greens. Whites and greens are the most common while reds against black are the most rare. Over time the water may evaporate from the stone. The dynamic nature of these stone's color combinations have captivated people for generations.
One Ancient Roman historian wrote that describing the opal's beauty is “a matter of inexpressive difficulty” because the gem is “made up of the glories of the most precious stones.” Shakespeare described the opal as “the queen of gems.” In the Middle Ages, opal jewelry was worn because it was seen as good luck since the opal was believed to contain the characteristics of all other gems. When opal rings changed color, people in the Medieval period believed it revealed the wearer's health. They also wore opal necklaces to assure good heart health.
