The Gemstones for October


Opal, often referred to as the “queen of gemstones,” is renowned for its charm. Opals have been treasured since ancient times, and exhibit a phenomenon known as “opalescence” where they display a stunning spectrum of colors, from fiery reds and oranges to brilliant blues and greens, resembling a rainbow. This remarkable phenomenon is referred to as “play-of-color.” The intricate pattern of color is created by the diffraction of light within the gemstone.

Known for its origins in India (where the first opals introduced to the Western world were found), Opal derives its name from the Sanskrit term “upala,” signifying a precious stone. In ancient Rome, it evolved into “opalus.”

Opal is mined in a variety of places. Australia boasts the world’s most prolific opal production for October’s birthstone. Other prominent areas include Mexico, Ethiopia, and Brazil. Additional opal deposits have been discovered in Honduras, Indonesia, Madagascar, Central Europe, Turkey, Peru, and the United States.


Often called “nature’s kaleidoscope,” tourmaline is a gem of remarkable diversity and beauty. Tourmaline has been prized for centuries, with its name derived from the Sinhalese word “turamali,” meaning “stone with mixed colors.” It was often mistaken for other gemstones due to its wide range of hues.

Tourmalines come in a spectacular array of colors, from vivid pinks and greens to deep blues and reds. Some even exhibit multiple colors in a single crystal, creating a captivating effect.

The majority of tourmaline extracted in Brazil throughout history has originated from pegmatites located in the state of Minas Gerais. These underground magma intrusions serve as the wellspring for a diverse array of precious gem minerals. Tourmaline is also found in Pakistan, Mozambique, Madagascar, Kenya, and the United States, specifically California and Maine.

Fast Facts About Opal

  • Opal is the gemstone traditionally associated with celebrating the 14th wedding anniversary.
  • Black opal is considered prized and found in Lightning Ridge, a small town in Australia. This region receives minimal rainfall and experiences soaring summer temperatures. The climate is so relentless that miners frequently seek refuge from the harsh heat by dwelling underground.
  • Opals are believed to enhance intuition, creativity, and emotional well-being. They have been said to have a deep connection to emotions and love. The Romans adored opals as symbols of hope and purity, while the Greeks believed opals were tears of joy shed by Zeus. Arab cultures thought opals fell from the sky in flashes of lightning.
  • Opals contain water, up to 20 percent, which makes them sensitive to rapid temperature changes. This unique water content contributes to Opal’s play of colors.
  • No two Opals are alike, making them perfect for those who cherish individuality.
  • There are a number of famous opals, but the “Aurora Australis” stands as the world’s most prized black opal. Discovered in 1938 within the Lightning Ridge region, the beautifully oval-cut and polished gem showcases a captivating harlequin pattern, predominantly adorned with striking red, green, and blue hues set against a dramatic black backdrop. Its impressive weight is recorded at 180 carats.

Fast Facts About Tourmaline

  • Tourmaline is known to be pyroelectric, meaning it can generate an electric charge when heated or subjected to pressure. This property has led to its use in various scientific instruments.
