October boasts the unique distinction of having two recognised birthstones: the captivating opal and the delicate pink tourmaline. Both gemstones offer a spectrum of beauty and symbolism, making them cherished choices for jewellery and meaningful gifts. This article will explore the history, geological origins, gemological properties, and cultural significance of these October birthstones, alongside guidance on their care and maintenance.
History and Lore
For centuries, opal has held a prominent place in lore and legend. Sources indicate it has been a symbol of love, hope, magic, and luck. Its captivating play of colour has fascinated cultures throughout history, making opal jewellery a consistently desirable choice. More recently, tourmaline has gained recognition as a modern October birthstone, celebrated for its calming energy and believed ability to bring peace and tranquility to the wearer.
The association of specific gemstones with months of the year evolved over time, with the modern birthstone list largely standardised in 1912 by the National Association of Jewelers. While opal has a longer historical connection to October, the inclusion of pink tourmaline provides a wider range of options and aesthetic preferences for those seeking a birthstone necklace or other jewellery.
Geological Formation and Sources
The provided sources do not detail specific geological formations or mining locations for either opal or tourmaline. However, they do indicate that both are natural gemstones, meaning each stone exhibits slight variations in colour, contributing to their unique beauty. The sources highlight the use of ethically sourced natural stones in jewellery production.
Gemological Properties
Opal is described as exhibiting a “mesmerising play of colours,” a defining characteristic of the gemstone. This iridescence is due to the diffraction of light caused by microscopic silica spheres within the stone. The sources do not provide details on opal’s chemical composition, hardness, or refractive index.
Pink tourmaline, on the other hand, is noted for its gentle pink shade, symbolising emotional healing. One source details a pink tourmaline gemstone as being 0.6-0.7 carats (7x5mm) and set in an 18-karat gold pendant. The sources do not provide a chemical formula or hardness rating for tourmaline.
A comparison of key properties, based on the limited information provided, is presented below:
| Property | Opal | Pink Tourmaline |
|---|---|---|
| Colour | Iridescent, play of colour | Pink |
| Symbolism | Creativity, inspiration, transformation | Emotional healing, love, compassion |
| Carat Weight (example) | N/A | 0.6-0.7 ct |
Symbolism and Metaphysical Beliefs
Opal is associated with creativity, inspiration, and transformation. It is considered a stone of hope and magic. Pink tourmaline, conversely, is linked to love, compassion, and emotional healing. It is believed to promote peace and tranquility. These symbolic meanings contribute to the gemstones’ appeal as personal and sentimental gifts, particularly for those celebrating birthdays or significant life events.
Materials and Craftsmanship
The sources emphasize the quality of materials used in crafting birthstone necklaces. Jewellery is made from 925 sterling silver and 14k gold vermeil (at least 2.5 microns of gold over sterling silver) to ensure lasting durability and a radiant finish. Gold vermeil is described as being five times thicker than standard gold plating. Some pieces are crafted from 18-karat solid gold. The use of ethically sourced natural stones is also highlighted.
Several brands offer October birthstone necklaces, including Ivy Laine Jewellery, La Côte Club, Abbott Lyon, Ella Creations Jewelry, Kendra Scott, and Honey Willow. These brands offer a variety of styles, from simple pendants to more elaborate designs.
Jewelry Care
Proper care is essential to maintain the beauty of opal and pink tourmaline jewellery. The sources recommend removing jewellery before showering, swimming, or exercising. Contact with perfumes, lotions, hairspray, and cleaning products should be avoided, as these can damage the finish. Jewellery should be stored individually in a pouch to prevent scratching. Regular cleaning with a soft, dry cloth is advised. For gold vermeil pieces, a polishing cloth can be used to maintain shine, but over-polishing should be avoided to preserve the plating.
Necklace Styles and Features
The sources describe a range of necklace styles featuring October birthstones. These include:
- Pendants: Available in various shapes and settings, including pear-shaped pink tourmaline set in 18k gold bezels.
- Chain Lengths: Adjustable chains, typically ranging from 16" to 18", offer versatility in wear.
- Removable Pendants: Some necklaces feature removable pendants, allowing for customization with other birthstone pendants.
- Star Set Pendants: Tourmaline set in a star setting.
- Huggie Earrings: White iridescent crystal earrings.
- Bracelets: Adjustable chain bracelets with Berry Illusion stones.
Conclusion
Opal and pink tourmaline represent the captivating beauty and diverse symbolism of October’s birthstones. Whether drawn to the iridescent play of colour in opal or the gentle pink hues of tourmaline, these gemstones offer a meaningful and personal connection. The emphasis on quality materials and craftsmanship ensures that October birthstone jewellery is not only aesthetically pleasing but also durable and cherished for years to come. The combination of historical significance, geological uniqueness, and symbolic meaning makes these gemstones a truly special choice for those born in the tenth month of the year.
