October is uniquely blessed with not one, but two recognized birthstones: opal and tourmaline. Both gemstones offer a stunning spectrum of colors and possess a rich history, making them cherished adornments and symbols of significance. This article will delve into the origins, properties, lore, and modern appreciation of these captivating October birthstones, drawing solely from available sources.
History and Lore
The story of opal, the traditional October birthstone, traces back to ancient origins. Its name is believed to have originated in India, where it was known as upala, meaning “precious stone” in Sanskrit. This term evolved into opalus in ancient Rome. Throughout history, opal has inspired a wealth of beliefs and symbolism. Ancient Greeks associated the stone with the gift of prophecy and protection from disease, while Bedouins believed opals contained lightning and descended from the sky during thunderstorms. Europeans considered opal a symbol of purity, hope, and truth, and for centuries, it was thought to embody the virtues of all colored stones.
Tourmaline, the modern October birthstone, enjoys a more recent rise to prominence as a birthstone, though its history as a valued gem stretches back centuries. While the sources do not detail its ancient history, they highlight its current appeal and symbolism.
Geological Formation and Sources
The provided sources offer limited information regarding the geological formation of either opal or tourmaline. Source [1] notes that opals are mined in various locations, but does not specify which. The sources do not provide any information on the geological processes involved in the formation of either stone, nor do they detail specific mining locations beyond the initial origin of opals in India.
Gemological Properties
While a comprehensive gemological profile is lacking in the provided sources, some key properties are mentioned. Opal is particularly valued for its “play-of-color,” a shifting display of rainbow hues. This phenomenon is a defining characteristic of the stone.
Tourmaline is noted for its wide array of colors, including pink, and is considered a desirable choice for jewelry designers. The sources mention that topaz is often treated to achieve additional colors, like blue topaz, but do not specify if this is also common for tourmaline.
A table summarizing the limited available properties is presented below:

Symbolism and Metaphysical Beliefs
Opal has long been associated with positive attributes. Historically, it symbolized purity, hope, and truth. More recently, it is linked to gentleness and compassion. The sources also mention that opal is the stone given to celebrate the 14th wedding anniversary.
Tourmaline, as a modern birthstone, represents love for humanity. The sources also connect topaz, a November birthstone, to boldness, intense energy, purpose, zeal, passion, self-confidence, kindness, and charity. While not directly attributed to tourmaline, the association with similar energetic qualities suggests a potential overlap in metaphysical beliefs.
The sources also briefly touch upon the practice of associating gemstones with days of the week, linking specific stones to planetary energies and desired attributes. For example, wearing a gold topaz on Sunday is believed to harness the Sun’s vibrant energy.
Care and Cleaning
The provided sources do not offer specific guidance on the care and cleaning of opal or tourmaline. However, given the mention of topaz’s Mohs hardness of 8, it can be inferred that gemstones generally benefit from careful handling and protection from scratches. Further research beyond these sources would be necessary to provide detailed cleaning instructions.
October Birthstone Gift Ideas
The sources offer a few suggestions for gifts featuring October birthstones. These include 18k Vermeil Asymmetrical Green Tourmaline Earrings, 18k Vermeil Moonstone & Tourmaline Earrings, and 14k-Gold Asymmetrical Opal, Carnelian & Multi-Stone Earrings. These examples demonstrate the versatility of both stones in contemporary jewelry design.
Modern vs. Traditional Birthstone Lists
The sources highlight the evolution of birthstone lists, noting the existence of both modern and traditional designations. The International Gem Society (IGS) acknowledges that jewelers continue to add options to the modern birthstone chart, with stones like spinel, citrine, and tanzanite being recent additions. In the United States, individuals often choose from both lists based on personal preference and affordability. Traditional stones, like turquoise, may be less expensive or more readily available than their modern counterparts.
Additional Birthstone Information
The sources also provide a brief overview of birthstones for other months, including garnet (January), amethyst (February), aquamarine (March), diamond (April), emerald (May), ruby (July), sapphire (September), and topaz (November). This broader context illustrates the rich tapestry of gemstone lore and symbolism associated with each month of the year.
Conclusion
Opal and tourmaline, the dual birthstones of October, represent a captivating blend of history, beauty, and symbolism. Opal, with its ancient roots and mesmerizing play-of-color, embodies purity, hope, and truth. Tourmaline, a more recent addition to the birthstone family, symbolizes love for humanity and offers a stunning array of colors. While the provided sources offer a glimpse into the world of these gemstones, further research is encouraged to fully appreciate their geological origins, gemological properties, and enduring appeal.
