October boasts not one, but two recognized birthstones: the captivating opal and the delicate pink tourmaline. Both gemstones offer unique appeal, steeped in history and symbolism, and increasingly popular choices for contemporary jewelry. This article will explore the characteristics, origins, and significance of these October birthstones, drawing upon available information regarding their properties and cultural relevance.
History and Lore
The association of specific gemstones with months of the year has evolved over time. While modern birthstone lists are largely standardized, historical variations existed. Opal, in particular, has a rich and often contradictory history. Sources indicate its symbolic meaning as a “soother of sadness & envy,” suggesting a historical belief in its ability to calm emotional turmoil. The sources do not provide details on the origins of this belief, but it highlights the long-held association of gemstones with emotional and spiritual well-being.
Pink tourmaline, while a more recent addition to the October birthstone designation, is similarly linked to positive attributes. It is specifically described as symbolizing “love, compassion and healing,” making it a meaningful choice for those seeking emotional balance and connection. The sources indicate that pink tourmaline is a relatively recent addition to the October birthstone list, gaining prominence alongside opal.
Geological Formation and Sources
The provided sources offer limited detail regarding the geological formation of either opal or pink tourmaline. However, one source specifies that the opal featured in a particular bracelet is “Australian opal,” indicating Australia as a significant source for this gemstone. The sources do not detail the specific geological processes involved in opal formation, which typically occurs in sedimentary environments where silica-rich water percolates into cracks and voids.
Similarly, the origin of the pink tourmaline is not explicitly stated beyond its presence in bracelets handmade in Bath, England. Tourmaline, in general, forms in igneous and metamorphic rocks, often in pegmatites, and can be found in various locations worldwide, including Brazil, Africa, and the United States.
Gemological Properties
The sources provide some, though limited, gemological data. Opal is described as a “semi-precious” stone, and the opal stones used in one bracelet measure approximately “3-4mm in size.” The same source details the availability of bracelets in both 14k gold filled and sterling silver settings. Another source features an opal set on a disc, made with 18K Gold plating.
Pink tourmaline is described as a birthstone for October and is featured in a 9kt gold bracelet with a 3mm gemstone. The sources do not provide details on the chemical composition, refractive index, or hardness of either gemstone. However, other sources indicate that opal is known for its play-of-color, a unique optical phenomenon caused by the diffraction of light within its internal structure.
A table summarizing the limited available data is provided below:
| Gemstone | Setting Options | Typical Size (mm) | Metal Purity |
|---|---|---|---|
| Opal | 14k Gold Filled, Sterling Silver, 18K Gold Plated | 3-4 | 18K, 14K |
| Pink Tourmaline | 9kt Gold | 3 | 9kt |
Symbolism and Metaphysical Beliefs
As previously mentioned, both opal and pink tourmaline are associated with positive emotional attributes. Opal is described as a “soother of sadness & envy,” while pink tourmaline symbolizes “love, compassion and healing.” These symbolic associations likely contribute to their popularity as birthstones and gifts.
One source highlights the sapphire as a gemstone known for its “calming and soothing properties, symbolizing love and affection.” This is a misattribution, as the bracelet features simulated sapphire, not opal. This highlights the importance of carefully evaluating source information, as marketing materials may sometimes contain inaccuracies.
Care and Cleaning
The sources offer practical advice on caring for the different metals used in the bracelets. Gold-plated jewelry should be stored in a soft pouch, away from direct sunlight and heat, and should not be worn while swimming or showering to prevent damage from chlorine and soapy water. Sterling silver is prone to tarnishing and should be stored in a sealed bag or airtight box, and regularly cleaned with a polishing cloth.
Specific care instructions for opal and pink tourmaline are not provided. However, general gemstone care guidelines recommend avoiding harsh chemicals, hot water, and ultrasonic cleaners, as these can damage delicate gemstones. Diamonds, if present in settings, can be cleaned with a diamond cleansing pen or warm soapy water and a soft brush.
Bracelet Styles and Materials
The sources showcase a variety of bracelet styles featuring opal and pink tourmaline. These include:
- Pink Tourmaline Solitaire Bracelet: A dainty 9kt gold bracelet featuring a single 3mm pink tourmaline.
- Opal Bar Bracelet: A bracelet with small, natural opal stones in either 14k gold filled or sterling silver.
- Opal Chain Bracelet: A bracelet featuring a pebble-shaped opal stone set on a disc, plated in 18K gold.
- Simulated Sapphire Flex Bracelet: A platinum finish sterling silver flexible bangle bracelet featuring a row of simulated sapphires.
- Opal Bracelet with Glass Crystals: A bracelet featuring 6mm bicone and round glass crystals alongside gold-filled spacer balls.
The materials used in these bracelets vary, including 14k gold filled, sterling silver, 9kt gold, 18K gold plating, and simulated gemstones.
Conclusion
Opal and pink tourmaline represent the dual beauty and symbolism of October’s birthstones. While the sources provide limited detailed gemological information, they highlight the historical and emotional significance of these gemstones. Opal, with its captivating play-of-color and association with emotional healing, and pink tourmaline, with its representation of love and compassion, offer meaningful choices for those seeking a connection to their birthstone. The variety of bracelet styles available, incorporating these gemstones with different metals and settings, ensures that there is an October birthstone bracelet to suit every taste and preference.
