As the leaves begin to change and the air becomes crisp, the birthstone of October brings warmth and vibrancy to the season. It also carries hopes for a better tomorrow and signifies the human spirit in its ultimate form.

With its kaleidoscope of colors and fiery flashes, opal is a true wonder of nature. It has captivated people for centuries with its shifting hues, which resemble the colors of the rainbow. Like the changing leaves, opals come in diverse shades and patterns, each as unique as those who wear them.

Opal is a mineraloid. Light refraction causes its distinctive play of color as it travels through microscopic spheres of silica arranged in a regular pattern. This play of color can include various appealing tints, such as red, orange, yellow, green, blue, and violet, and can appear as a breathtaking iridescent display known as "fire."

October’s birthstone, opal, brings vibrant warmth to the autumn season with its unique kaleidoscope of colors. Known for its iridescent “fire,” opal captivates with hues of red, blue, green, and violet, attributed to the microscopic silica spheres that refract light. Originating from ancient beliefs, opals are symbols of hope, creativity, and emotional healing, valued for their mystical qualities and popularity in modern jewelry. Designers often pair opal with precious metals to create intricate rings, earrings, and pendants, while its care requires gentle handling to preserve its natural beauty and prevent damage.

Origin of Opal

The origin of the name "opal" is believed to have come from the ancient Sanskrit word "upala," implying a "precious stone." The word was then adopted by the ancient Greek language as "opallios," which refers to “seeing a change of color."

Opals are found worldwide, with most of the world's supply coming from Australia. Australia is known for producing some of the finest opals, including the highly prized black opal. Other significant sources of opals include Ethiopia, Mexico, Brazil, and the United States, particularly Nevada and Oregon.

Symbolism Behind Opal

Opals were highly prized in ancient Rome due to the widespread belief that they could foretell the future. They were also presented as gifts to fend off evil and guard against disease and were widely seen as a symbol of optimism and purity.

In the Middle Ages, opals were worn as talismans for good fortune and protection. The exotic gemstones were thought to treat everything from eye illnesses to gastrointestinal issues. 

Opals were also often associated with the powers of invisibility and protection. Some believed the gemstone could render its wearer invisible, while others thought it could protect them from danger and evil spirits.

Opal gemstones have become increasingly connected with modern creative and cultural movements. The celebrated Art Nouveau style of the 19th century greatly admired opals for their rare and dazzling dance of color. 

This stunning design's elevated prominence can be attributed partly to the work of artists like René Lalique and Louis Comfort Tiffany, who regularly used it in their jewelry designs.

According to an Aboriginal legend, the creator of the world came down to Earth on a rainbow to bring a message of peace to all humankind. As he stepped off the rainbow, the colors scattered and fell to the ground, creating the opals we know today.

The legend of the opal's play of color maintains that in ancient times, it was believed that opals contained the beauty of all other gemstones. According to a myth, opals were created when a massive lightning bolt struck the Earth and fused the rainbow colors into one stone.

Opals are still valued for their exceptional beauty and functional qualities. Given their association with October, they have come to represent perseverance, originality, and sensitivity.

However, you may be required to hire the service of an industry professional to avoid causing irreparable damage to your opal. To stay safe, remember that warm, soapy water is the most secure and effective cleaning method for October's birthstone.

Other cleaning techniques could potentially harm your opal or the filler material. Please also note that extended contact with water may cause the glue in opal doublets and triplets to become less effective. Try to keep them out of high or rapidly changing temperatures, given that even a natural opal can shatter due to overexposure to extreme heat.

On the Mohs hardness scale, this October birthstone falls between 5 and 6.5. Therefore, you are advised to keep your opal in a box alone to protect it from damage by jewelry that may be set with other tougher gems. Several precious stones, including diamonds, rubies, sapphires, and emeralds, can scratch the October birthstone, so your best bet is to give it some space.
