October boasts the unique distinction of having two recognized birthstones: pink tourmaline and opal. Both gemstones offer a captivating beauty and rich history, making them cherished choices for jewelry and symbolic representations of those born in the tenth month of the year. This article delves into the origins, properties, and significance of these radiant gems, providing a comprehensive overview for enthusiasts and prospective buyers alike.
History and Lore
The association of both tourmaline and opal with October has evolved over time. Traditionally, opal held the sole position as the October birthstone. However, in recent years, pink tourmaline has gained prominence as the modern alternative, offering a wider range of color options and increasing availability. The name “tourmaline” itself originates from the Sinhalese word turamali, meaning “stone of mixed color,” a fitting description for a gem known for its diverse hues.
Opal has a long and storied past, steeped in folklore and symbolism. Sources indicate that opal is believed to possess healing properties, with the stone reportedly turning gray or dull yellow when the wearer is ill or injured. Pink opal, in particular, is thought to offer relief from ailments affecting the eyes, spleen, throat, pancreas, and bone marrow, while also fostering a sense of peace and devotion within families.
Tourmaline’s history, while less extensively detailed in the provided sources, is marked by its recognition for its varied colors. The specific raspberry or purple tones within tourmaline are classified as rubellite, adding to the gem’s appeal and diversity.
Geological Formation and Sources
Pink tourmaline forms in a variety of geological environments, often within granite pegmatites, which are coarse-grained igneous rocks. The presence of different elements during the gem’s formation dictates its color. Fine quality pink tourmaline is sourced from several regions globally, including Brazil, Nigeria, Mozambique, and various areas of West Africa.
Opal, unlike tourmaline, is a hydrated amorphous form of silica. This means it doesn’t have a crystalline structure like many other gemstones. Opal forms in cracks and voids in rocks, where silica-rich water deposits silica gel. Over time, this gel hardens and forms opal. The sources do not specify the geological formation of opal, but focus on its presence in jewelry.
Gemological Properties
Pink tourmaline exhibits a hardness of 7-7.5 on the Mohs scale, making it relatively durable for everyday wear. However, it is susceptible to damage from excessive heat. Its chemical composition is complex, varying based on the specific elements present, but it is a borosilicate mineral.
Opal, on the other hand, has a lower hardness, typically ranging from 5.5 to 6.5 on the Mohs scale. This makes it more prone to scratches and requires more careful handling. The provided sources detail an oval-cut opal measuring 6x8mm with a carat weight of 1.5ct and a VS clarity grade. Opal is known for its play-of-color, a unique optical phenomenon caused by the diffraction of light within its internal structure.
The following table summarizes the key gemological properties:
| Property | Pink Tourmaline | Opal |
|---|---|---|
| Hardness (Mohs) | 7-7.5 | 5.5-6.5 |
| Chemical Composition | Borosilicate | Hydrated Silica |
| Clarity | Varies | VS Grade |
| Durability | Good | Moderate |
Symbolism and Metaphysical Beliefs
Both pink tourmaline and opal carry significant symbolic weight. Opal is traditionally associated with faith in life, confidence, and healing. It is believed to foster a sense of peace and devotion, strengthening familial bonds.
Pink tourmaline is also linked to positive energies, believed to balance hormones and potentially aid in combating certain genetic disorders. It is thought to calm the nerves and enhance creativity in the wearer. The sources highlight the opal’s enchanting iridescence as representing celestial wonder, making it a meaningful choice for those seeking a connection to the cosmos.
Care and Cleaning
Maintaining the beauty of both pink tourmaline and opal requires careful attention. Pink tourmaline can be cleaned with simple soap and water, but should be protected from excessive heat. Harsh chemicals should be avoided to prevent damage.
Due to its lower hardness, opal requires even more delicate care. It is susceptible to scratches and should be stored separately from harder gemstones. Cleaning opal jewelry should also be done with mild soap and water, avoiding harsh chemicals and ultrasonic cleaners.
Jewelry Styles and Market Availability
The provided sources showcase a variety of jewelry featuring both pink tourmaline and opal. Pink tourmaline is featured in 18K rose gold rings, baguette stack bands, and eternity rings, often paired with diamonds. Opal is found in engagement rings, earrings, pendants, and full eternity bands, frequently set in 14K rose gold or yellow gold. Colourless moissanite is often used as a complementary gemstone, enhancing the opal’s brilliance.
Several retailers, including Angara and Blue Nile, are recommended as sources for purchasing pink tourmaline jewelry, with Angara offering the most extensive selection online. The sources also mention specific pieces, such as a 1.5ct oval-cut opal ring framed by moon-inspired moissanite, and a watermelon tourmaline ring set in 18K rose gold.
Conclusion
Pink tourmaline and opal, the captivating birthstones of October, offer a diverse range of beauty, symbolism, and geological origins. While differing in hardness and formation, both gems hold a special place in the world of gemstones, cherished for their unique qualities and the positive energies they are believed to embody. Whether seeking a classic opal with its mesmerizing play-of-color or a vibrant pink tourmaline with its calming properties, October-born individuals have two radiant choices to celebrate their birth month.
