Opal, the designated birthstone for the month of October, is a gemstone that defies the conventional crystalline structure found in most jewels. Renowned for its mesmerizing and iridescent play of color, opal is a hydrated amorphous silica, a non-crystalline mineral that contains water within its structure. This unique composition is responsible for its most distinguishing feature: as light interacts with microscopic silica spheres inside the stone, it scatters into a spectrum of hues, creating an ever-shifting display of color. While natural opal, particularly from Australia, is considered a marvel of nature and holds significant value, its practical use in fine jewelry has historically been limited due to its relative softness and sensitivity to environmental conditions. The October birthstone represents a fascinating intersection of geological wonder, historical lore, and personal expression. This article explores the gemstone’s significance, its journey through history and myth, its geological origins, and its modern interpretation by jewelry brand Kendra Scott, which has crafted an accessible and durable version of this October gemstone for a contemporary audience.
History and Lore
The history of opal is as multifaceted and colorful as the stone itself. For centuries, this gemstone has been the subject of both admiration and superstition, its reputation shifting dramatically over time. In ancient history, opal was highly prized. The Romans considered it the most precious of all gemstones, believing it contained the colors of all other gems. The ancient Greeks also held opal in high regard, associating it with the power of prophecy. For centuries, opal was a symbol of hope, innocence, and purity. However, its perception suffered a significant downturn in the 19th century, largely due to a negative portrayal in literature. This negative perception eventually faded, and opal has since regained its status as a symbol of hope, inspiration, and individuality.
The journey of opal to becoming a modern birthstone is part of a larger tradition. The concept of assigning specific gemstones to months of the year has evolved over centuries, with roots in biblical texts and the breastplate of Aaron described in the Book of Exodus, which featured twelve stones representing the twelve tribes of Israel. The modern list of birthstones, which includes opal for October, was formalized in 1912 by the American National Retail Jeweler's Association (now known as Jewelers of America). This standardized list has since been updated, but opal has remained the primary birthstone for October, a testament to its enduring appeal and unique visual properties. In the context of contemporary jewelry, the October birthstone is not only a nod to tradition but also a celebration of personal expression and style, serving as a meaningful element that allows individuals to wear a piece that resonates with their identity and heritage.
Geological Formation and Sources
The formation of natural opal is a complex geological process that requires specific environmental conditions. It is formed through the precipitation of silica-rich water in the crevices of rocks. This typically occurs in regions with arid climates, where water can seep into the ground, deposit silica, and then evaporate, leaving behind a silica-rich structure. The presence of water is crucial to the formation of opal and also contributes to its susceptibility to cracking or dehydrating when exposed to dry conditions.
Australia is by far the most well-known source of high-quality natural opal, accounting for 95% of the world’s production. Other notable sources include Ethiopia, Mexico, and Brazil, each producing opal with distinct characteristics and color patterns. The specific geological conditions in these regions determine the type of opal that is formed, from the precious black opal of Lightning Ridge in Australia to the vibrant fire opals of Mexico.
While natural opal is a marvel, its use in fine jewelry is often limited due to its fragility and sensitivity to heat and dry environments. This has led to the development of alternative materials that mimic its appearance. Kendra Scott’s interpretation of the October birthstone—the Champagne Opal Crystal—is a synthetic or man-made material designed to mimic the look of natural opal with improved durability and affordability, making the essence of the October gemstone accessible without the fragility or cost of a natural stone.
Gemological Properties
Understanding the gemological properties of opal is essential for appreciating its unique characteristics and for its proper care. The fundamental property that distinguishes opal from most other gemstones is its lack of a crystalline structure. It is a hydrated amorphous silica, meaning it is non-crystalline and contains water within its structure, typically ranging from 3% to 21% by weight. This water content is a critical factor in its physical behavior and care requirements.
The most celebrated property of opal is its play of color, or iridescence. This optical phenomenon is caused by the diffraction of light as it passes through the microscopic silica spheres and voids within the stone. The size and arrangement of these spheres determine the specific colors that appear. For the play of color to be visible, the spheres must be of a uniform size and arranged in a three-dimensional lattice. This precise structure is what creates the spectacular spectral displays that make opal so captivating.
In terms of hardness, opal is relatively soft on the Mohs scale, typically ranging from 5.5 to 6.5. This makes it susceptible to scratching and abrasion, especially when compared to harder gemstones like sapphire (Mohs 9) or diamond (Mohs 10). Its lack of cleavage (a tendency to break along flat planes) is an advantage, but its sensitivity to thermal shock is a significant concern. Sudden temperature changes can cause the stone to crack due to the expansion and contraction of water within its structure.
Kendra Scott’s Champagne Opal Crystal is a man-made alternative that addresses some of these durability concerns. While it is designed to mimic the appearance of natural opal, its synthetic composition likely offers greater stability and resistance to environmental factors, making it more suitable for everyday wear. However, it still benefits from proper handling and cleaning to maintain its beauty.
Symbolism and Metaphysical Beliefs
Beyond its physical beauty, opal carries a rich tapestry of symbolism and metaphysical beliefs that have evolved over centuries. Historically, opal has been associated with hope, purity, and truth. It was often considered a stone of inspiration and creativity, believed to enhance imagination and spontaneity. In various cultures, opal has been linked to emotional healing and balance.
In modern metaphysical circles, opal is often associated with emotional expression and personal growth. It is believed to stimulate the mind, encourage self-expression, and inspire innovation. In a more emotional sense, opal is said to soothe the heart and promote emotional balance, offering comfort during times of stress or uncertainty. These symbolic meanings have been carried into the world of contemporary jewelry, where the October birthstone serves as a symbol of personal growth, confidence, and authenticity.
Kendra Scott’s Champagne Opal Crystal carries these symbolic meanings into its jewelry designs. The brand’s October birthstone pieces are not only visually striking but also serve as a symbol of personal growth, confidence, and authenticity. By wearing an October birthstone, individuals are reminded of their unique journey and the beauty of their own story. The brand emphasizes customization and self-discovery, and the October birthstone serves as a meaningful element in their Birthstone Inspired Collection.

Care and Cleaning
Proper care is essential to maintain the beauty and longevity of opal jewelry, whether natural or synthetic. Because natural opal is relatively soft and sensitive, it requires special care. Kendra Scott’s Champagne Opal Crystal is designed to be more durable and suitable for everyday wear, but it still benefits from proper handling and cleaning.
Key care instructions for opal jewelry include: - Avoid exposure to harsh chemicals: This includes household cleaners, perfumes, and lotions, which can damage the surface of the stone or the metal setting. - Store the jewelry in a cool, dry place: Opal is sensitive to temperature changes and can dry out or crack if exposed to extreme conditions. It should be kept away from direct sunlight and heat sources. - Clean the jewelry with a soft cloth or a mild soap and water solution: Avoid using ultrasonic cleaners or steamers, as these can potentially damage the stone or the metal. - Remove the jewelry before swimming, showering, or engaging in physical activities: This prevents accidental damage or exposure to water and chemicals that could be harmful. - Avoid stacking the jewelry with other pieces: This can cause scratches or abrasions to the softer surface of the opal.
