For individuals born on October 23rd, their birthstone is a unique pairing of Opal and Tourmaline, two gemstones celebrated for their vibrant colors and symbolic associations with hope and confidence. While Opal is considered the traditional birthstone for October, and Tourmaline the modern counterpart, the two are often grouped together in October’s birthstone lore. These gemstones not only reflect the dynamic and diverse nature of October-born individuals but also offer a rich tapestry of geological, historical, and metaphysical significance.
This article explores the origins, properties, cultural meanings, and modern significance of Opal and Tourmaline, with a special focus on their role as birthstones for those born on October 23rd. Drawing from multiple authoritative and historical sources, we will uncover the deep-rooted traditions and scientific properties that make these stones so meaningful.
The Dual Birthstones of October
October is the only month in the calendar year that has two official birthstones: Opal and Tourmaline. This dual designation is relatively rare and reflects the diverse range of colors and symbolic meanings associated with both gemstones. While Opal is often regarded as the traditional birthstone for October, and Tourmaline the modern counterpart, their combination is especially fitting for October 23rd, a date that aligns with themes of personal growth, self-assurance, and positive transformation.
Opal: The Traditional Birthstone of October
Opal is an amorphous, hydrated silica mineral that is prized for its play-of-color—a phenomenon where the gemstone displays a shifting array of colors under light. This effect is caused by the diffraction of light through microscopic silica spheres within the stone. Opal is not a crystalline gemstone in the conventional sense, yet it has been revered for centuries for its beauty and its perceived mystical properties.
Opal has a long and storied history. It was first known in the West through imports from India, where it was called Upala, meaning "precious stone." The name was later Latinized to Opalus, and it eventually became the English Opal. In ancient Greece, opal was believed to have the power to protect against disease and to grant prophetic insight. In Europe, it came to symbolize purity, hope, and truth, and it was often associated with romantic love and divine inspiration.
Opal is also a traditional gift for the 14th wedding anniversary, underscoring its role as a symbol of lasting beauty and enduring hope. For those born on October 23rd, Opal is more than just a gemstone—it is a source of confidence, prosperity, and gratitude. Wearing Opal is believed to enhance self-assurance, attract abundance, and foster a sense of inner balance and spiritual clarity.
Tourmaline: The Modern Birthstone of October
Tourmaline, in contrast to Opal, is a crystalline gemstone that comes in a wide range of colors. Its name comes from the Sinhalese word toramalli, meaning "stone with mixed colors." This diversity in color is one of the defining features of Tourmaline, and it makes it a versatile gemstone for jewelry and spiritual practices alike.
Tourmaline is chemically complex, consisting of a group of cyclosilicate minerals with a general formula that includes elements such as boron, aluminum, sodium, lithium, and iron. The color of Tourmaline is primarily determined by the presence and concentration of these elements. For example, pink tourmaline (often called Rubellite) gets its color from manganese, while green tourmaline is typically colored by iron or copper.
Tourmaline is a modern birthstone for October, introduced more recently than Opal. It is also a traditional gift for the 8th wedding anniversary, symbolizing love, compassion, and strength. Each color of Tourmaline carries its own symbolic meaning. Pink Tourmaline is associated with love and compassion, while Green Tourmaline symbolizes courage and strength. Black Tourmaline, on the other hand, is often used for protection and grounding.
For those born on October 23rd, Tourmaline is believed to offer emotional balance, spiritual clarity, and protection from negative energy. It is also associated with confidence and positive transformation, making it a powerful complement to Opal in the October birthstone tradition.
Geological Formation and Sources
Opal: The Unique and Ephemeral Gem
Unlike most gemstones, Opal is not a crystalline mineral but an amorphous hydrated silica (SiO₂·nH₂O). It forms in the pores of volcanic rock and sedimentary deposits, where water containing dissolved silica has slowly deposited over time. Opal is found in various locations around the world, but Australia is by far the largest and most well-known source of precious opal.
Other notable sources of Opal include Ethiopia, Brazil, Mexico, Central Europe, Honduras, Indonesia, Madagascar, Peru, Turkey, and the United States. Ethiopian Opal, in particular, has gained prominence in recent years for its vibrant colors and high-quality play-of-color, often rivaling that of Australian Opal.
Opal is known for its softness, with a Mohs hardness of 5–6, making it susceptible to damage from scratches, heat, and dehydration. Because of this, Opal jewelry must be handled with care and stored in a humid environment to prevent cracking or breaking.
Tourmaline: A Versatile and Colorful Gemstone
Tourmaline is a cyclosilicate mineral that forms in pegmatite deposits, where molten rock cools slowly, allowing large crystals to develop. The most significant sources of Tourmaline are Brazil, Afghanistan, Pakistan, Kenya, Madagascar, Mozambique, and the United States (particularly in California and Maine).
Tourmaline is known for its wide range of colors, which is a result of variations in trace elements. For example:
- Rubellite (Pink Tourmaline) contains manganese, which gives it its pink to red color.
- Verdelite (Green Tourmaline) contains iron or copper, responsible for its green hue.
- Indicolite (Blue Tourmaline) contains iron, which imparts a blue or blue-green color.
- Black Tourmaline (Schorl) is the most common variety and contains iron and manganese, giving it a deep black color.
Tourmaline is relatively hard, with a Mohs hardness of 7–7.5, making it suitable for most types of jewelry. It is also piezoelectric, meaning it can generate an electrical charge when subjected to mechanical stress. This property was first discovered in the 19th century and has since been used in various scientific and technological applications.
Symbolism and Metaphysical Properties
Opal: A Stone of Transformation and Hope

Care and Maintenance of Opal and Tourmaline
Caring for Opal
Due to its softness and susceptibility to dehydration, Opal requires special care to maintain its beauty and longevity. It should be stored in a humid environment, such as a closed jewelry box or a silica gel pouch, to prevent cracking. Opal should also be avoided in extreme temperatures, as heat can cause it to dry out and lose its luster.
When cleaning Opal, it is best to use a soft, damp cloth and avoid using harsh chemicals or ultrasonic cleaners, which can damage the stone. Opal should also be removed before swimming, showering, or exposure to chemicals, as these can strip it of its moisture and reduce its brilliance.
Caring for Tourmaline
Tourmaline is much more durable than Opal, with a hardness of 7–7.5 on the Mohs scale, making it suitable for most types of jewelry. It can be cleaned with warm, soapy water and a soft brush, and it is generally safe to use ultrasonic cleaners as well.
Tourmaline is also piezoelectric, meaning it can generate an electrical charge when subjected to mechanical stress. While this property is not harmful, it is something to be aware of when handling or storing the gemstone.
Tourmaline should be stored in a dry, cool place, and it is best to avoid exposing it to extreme temperatures or direct sunlight for prolonged periods, as this can alter its color or reduce its brilliance.
