The sources emphasize its role as a modern alternative and complement to opal, known for its "rainbow of vibrant hues." Pink tourmaline is specifically associated with love, compassion, and emotional healing. It is often recommended for those seeking to open their hearts and invite joy, making it a gemstone deeply connected to emotional well-being and spiritual practices. Its gentle yet bold energy is said to support the compassionate spirit of those who wear it, particularly resonating with the harmonizing nature of Libra, which also falls within October.
Topaz is identified as the primary zodiac birthstone for Scorpio, the sign that governs the period from October 23 to November 21. While the historical lore for topaz is less detailed in the provided sources compared to opal, it is clearly positioned as a stone of strength, clarity, and transformation. These qualities align seamlessly with the traits often ascribed to Scorpio individuals—assertive, trustworthy, and deeply connected to their inner emotions. The sources note that topaz, along with turquoise, is listed as a gemstone for those born on October 23, with specific associations for Friday births and even a designated gemstone for the 11 PM hour (Iolite). This intricate system of assigning different stones for different times and days underscores the personalized and multifaceted approach to October 23 birthstones.
Geological Formation and Sources
Understanding where these gemstones originate provides insight into their rarity and value. Each stone forms under distinct geological conditions and is mined from specific regions around the world.
Opal is a sedimentary gemstone, formed from the silica-rich waters that seep into cracks and voids in the earth's crust.

The most productive fields for the October birthstone are located in Australia, which is renowned for producing high-quality opal. Other significant sources include Ethiopia, Mexico, and Brazil, each contributing unique varieties to the global market. Australian opal, particularly from regions like Coober Pedy and Lightning Ridge, is often considered the benchmark for quality.
Tourmaline is a complex borosilicate mineral that crystallizes in igneous and metamorphic rocks. Its remarkable range of colors is due to the presence of various trace elements within its crystal structure. While the provided sources do not specify mining locations for tourmaline, its formation is typically associated with granite pegmatites. The sources highlight its versatility and vibrant hues, making it a popular choice for jewelry. Pink tourmaline, specifically, is prized for its consistent color, ranging from pale blush to intense magenta, and is often set in rose gold or silver to enhance its delicate beauty.
Topaz is a fluorine-containing aluminum silicate mineral that typically forms in pegmatites and high-temperature hydrothermal veins. While the sources do not detail specific mining locations for the topaz associated with October 23, topaz is mined in various countries, including Brazil, Pakistan, Russia, and the United States. The gem's clarity and color, which can range from colorless to blue, yellow, or brown, are influenced by its formation environment and post-crystallization treatments. The sources emphasize its role as a zodiac stone for Scorpio, valued for its symbolic strength and transformative energy.
Gemological Properties
A scientific examination of these gemstones reveals their physical and optical characteristics, which determine their durability, care requirements, and value.
Opal
Opal is unique among gemstones due to its amorphous, non-crystalline structure. It is composed of hydrated silica (SiO₂·nH₂O) and is relatively soft, with a Mohs hardness of 5.5 to 6.5. This makes it susceptible to scratching and abrasion, requiring careful handling. Its refractive index typically ranges from 1.37 to 1.45. The most prized characteristic is its play-of-color, caused by the diffraction of light through microscopic silica spheres. Opals can exhibit a wide range of base body colors, from white to black, with the color play appearing in various spectral hues.
Tourmaline
Tourmaline is a complex mineral with a hardness of 7 to 7.5 on the Mohs scale, making it more durable than opal and suitable for everyday wear. Its chemical formula is complex, varying based on its composition, but it is generally a borosilicate. Tourmaline has a high refractive index, typically between 1.62 and 1.65, and strong pleochroism (exhibiting different colors when viewed from different angles). Pink tourmaline, specifically, is valued for its consistent color saturation and clarity.
Topaz
Topaz is a silicate mineral with a hardness of 8 on the Mohs scale, making it one of the harder gemstones and quite durable for jewelry. Its chemical formula is Al₂SiO₄(F,OH)₂. It has a refractive index ranging from 1.61 to 1.63. Topaz is known for its excellent clarity and can be found in a variety of colors, though the most common in jewelry are blue, yellow, and pink. The blue variety often results from irradiation and heat treatment of colorless or yellow topaz.
The following table summarizes the key gemological properties of the three October 23 birthstones, as derived from the provided sources:
