History and Lore
Opal has a long and storied history, dating back to ancient civilizations. The name "opal" is believed to have originated in India, where it was known as upala, meaning "precious stone." In ancient Rome, the name evolved into opalus, and the gemstone was revered for its unique play-of-color, a phenomenon that creates a shifting display of light and color. The ancient Greeks believed opal granted the power of prophecy and protection from disease, while the Romans associated it with good luck and divination.
By the Middle Ages, opal had become a symbol of purity, hope, and truth in Europe. It was also believed to embody the virtues of all other colored gemstones. During the Victorian era, opal gained popularity in jewelry, especially in mourning rings and brooches. The gemstone was thought to be a powerful symbol of love and loyalty, making it an ideal choice for romantic jewelry.
Tourmaline, though less widely known in ancient times, has also been admired for its beauty and versatility. The name "tourmaline" comes from the Sinhalese word turamali, meaning "stone of mixed colors." This name perfectly captures the gem’s ability to display a wide range of colors, from deep pinks and purples to vibrant greens and blacks. Tourmaline with raspberry or purple tones is known as rubellite, while the green and pink combination is referred to as watermelon tourmaline.
Both opal and tourmaline have been used in jewelry and decorative arts for centuries, with their popularity waxing and waning depending on cultural and fashion trends. Today, they are recognized as two of the most distinctive and versatile birthstones, especially in the design of October birthstone wedding rings.
Geological Formation and Sources
The geological formation and sourcing of opal and tourmaline are as varied as their appearances. Opal is typically formed in volcanic or sedimentary rock, where water seeps into the cavities and deposits silica. Over time, this silica hardens into opal. Unlike most gemstones, opal does not have a crystalline structure and instead is made up of amorphous silica with water content varying between 5% and 30%. This lack of a crystalline structure is what allows opal to display its famous play-of-color.
Opal is most commonly found in Australia, which is the world’s largest producer. Other significant sources include Brazil, Mexico, Ethiopia, and Indonesia. Each of these regions produces opals with unique color patterns and characteristics. For example, Australian opals are known for their vivid rainbow colors, while Ethiopian opals often exhibit a black or dark body tone, which enhances the play-of-color.
Tourmaline, on the other hand, is a crystalline mineral that forms in a variety of geological environments, including granite pegmatites and metamorphic rocks. Its diverse color palette is due to the presence of different trace elements within the crystal structure. Pink tourmaline, for instance, is colored by manganese, while green tourmaline owes its hue to iron.
The most notable sources of tourmaline include Brazil, Nigeria, Mozambique, and various regions of West Africa. Brazilian tourmaline, particularly rubellite, is highly sought after for its intense color and clarity. Tourmaline from Mozambique and Nigeria is also prized for its quality and affordability.
When selecting tourmaline for a wedding ring, it is important to consider both color and clarity. High-quality tourmaline is typically free of inclusions and has a vibrant, saturated color. While tourmaline is relatively hard—ranging from 7 to 7.5 on the Mohs scale—it is still a gemstone that requires careful handling and proper care to ensure its longevity.
Gemological Properties
Understanding the gemological properties of opal and tourmaline is essential for anyone considering these gemstones for a wedding ring. These properties determine not only the durability and beauty of the gemstone but also how it should be set and cared for.
Opal
Opal is a unique gemstone that does not have a crystalline structure. Its chemical composition is primarily amorphous silica (SiO₂·nH₂O), with the water content affecting its stability and appearance. Opal’s Mohs hardness is relatively low, ranging from 5 to 6.5, which makes it more susceptible to scratches and fractures than harder gemstones like diamonds or sapphires. Additionally, opal is porous, which means it can absorb moisture and oils, and it can also be sensitive to extreme temperatures and chemicals.
The play-of-color is one of opal’s most distinctive features. This phenomenon occurs due to the refraction of light through the silica spheres that make up the opal’s structure. When light enters the gemstone, it is scattered in different directions, creating a shifting display of colors that can resemble a rainbow, fireworks, or even galaxies. The intensity and variety of play-of-color depend on the arrangement and size of the silica spheres and the water content of the opal.
Because of its delicate nature, opal is often set in protective settings that minimize exposure to impacts and abrasions. It is also recommended to avoid harsh cleaning methods, such as ultrasonic cleaners or steam cleaning, which can damage the gemstone. Instead, a gentle cleaning with warm, soapy water and a soft cloth is the best way to maintain an opal’s brilliance.
Tourmaline
Tourmaline is a crystalline mineral that belongs to the tourmaline group of silicate minerals. Its chemical composition is complex and can vary depending on the trace elements present. The general formula for tourmaline is XYZ₃(Si₆O₁₈)(BO₃)₃(OH)₄, where X, Y, and Z represent different elements such as sodium, calcium, magnesium, aluminum, iron, and manganese.
Tourmaline’s hardness on the Mohs scale ranges from 7 to 7.5, making it a relatively durable gemstone that can withstand daily wear in a wedding ring. However, it is important to note that tourmaline has cleavage, meaning it can be prone to chipping or breaking if struck at certain angles. This characteristic makes it essential to choose a secure setting for tourmaline rings, such as a bezel or tension setting, which helps protect the gemstone from impacts.
Tourmaline is also known for its piezoelectric properties, meaning it can generate an electric charge when subjected to pressure or heat. This unique property is not relevant to its use in jewelry but is an interesting scientific fact that highlights the gemstone’s complexity.
In terms of color, tourmaline is one of the most versatile gemstones available. It can display a wide range of hues, from deep pinks and purples to vibrant greens, blues, and blacks. This versatility makes tourmaline an excellent choice for custom jewelry design, as it can be matched to a variety of styles and preferences.
Tourmaline is also relatively resistant to chemicals and heat, making it easy to clean and maintain. A simple soap and water solution is typically sufficient to keep tourmaline jewelry looking its best. However, it is still advisable to avoid exposing tourmaline to high temperatures for prolonged periods, as this can affect its color and structure.
Symbolism and Metaphysical Beliefs
Both opal and tourmaline are associated with a variety of symbolic and metaphysical meanings that have been passed down through history and continue to influence their use in jewelry today. These meanings are rooted in cultural beliefs, historical traditions, and spiritual practices, and they contribute to the emotional and symbolic value of October birthstone wedding rings.
Opal
Opal is often associated with mystery, intuition, and emotional balance. In many cultures, it is believed to enhance emotional sensitivity and spiritual insight, making it a powerful stone for those who seek inner harmony and self-awareness.

In modern times, opal is often used in wedding rings and other romantic jewelry as a symbol of love, loyalty, and emotional depth. Its iridescent colors are said to represent the sparkling emotions of a loving relationship, while its unique and unpredictable nature reflects the unpredictability and beauty of love.
Tourmaline
Tourmaline is associated with a wide range of metaphysical properties, depending on its color and variety. In general, tourmaline is believed to ground and stabilize the mind and body, promoting emotional balance, mental clarity, and spiritual protection.
Pink tourmaline, for example, is often referred to as the stone of unconditional love. It is believed to open the heart chakra, promoting compassion, self-love, and emotional healing. This makes it an ideal gemstone for wedding rings, as it is thought to strengthen love and deepen emotional connections between partners.
Rubellite, the raspberry and purple variety of tourmaline, is associated with passion, creativity, and transformation. It is believed to stimulate creative energy and emotional expression, making it a popular choice for artistic and expressive individuals.
Watermelon tourmaline, with its green and pink coloration, is thought to combine the healing properties of green tourmaline with the emotional warmth of pink tourmaline. It is often used in jewelry to promote emotional balance, renewal, and vitality.
