Opal, celebrated as the primary birthstone for October, is a gemstone steeped in history, mythology, and a dazzling display of color. While pink tourmaline shares the honor as a modern October birthstone, opal’s rich past and unique optical properties have captivated cultures for millennia. This article will delve into the history, geological origins, gemological characteristics, symbolism, and care of this extraordinary gemstone, drawing exclusively from available sources.
History and Lore
The allure of opal extends back to antiquity, with various civilizations attributing mystical properties and origins to the stone. Ancient Greeks believed opals were formed from the joyful tears of Zeus after his victory over the Titans, imbuing the gem with protective energies and the power of prophecy and wisdom. They also associated the stone with benefits for the skin and eyes. Arabic legends describe opals arriving on Earth within bolts of lightning, while Aztec cultures believed the Fire Opal fostered creativity and new beginnings. The Indian Goddess of Rainbows, according to legend, transformed herself into an opal to evade unwanted attention.
Throughout history, opals have been treasured possessions. In the Roman Empire, they were considered symbols of love and hope. These gems have adorned crowns, necklaces, and even scepters, demonstrating their historical significance and value. Despite periods of superstition, particularly in the 19th century, opal experienced a resurgence in popularity in the 20th century and remains a highly sought-after gemstone today. It is also traditionally gifted to celebrate a 14th wedding anniversary.
Australian Aboriginal people hold a unique creation story for opal, believing it originated from the footprints of the Creator as they descended to Earth. This belief underscores the deep cultural connection to the stone within Indigenous Australian communities.
Gemological Properties
Opal is renowned for its play-of-color, a mesmerizing display of iridescent hues that sets it apart from other gemstones. This phenomenon is caused by the diffraction of light passing through microscopic silica spheres within the stone. While the provided sources do not detail the specific chemical composition or refractive index of opal, they emphasize its visual brilliance, comparing it to “a lightning bolt flashing in a rainbow.”
The sources highlight the diversity of opal, with variations in color and pattern. White opals, exhibiting incredible rainbow colors, are specifically mentioned. The dimensions of an opal featured in a pair of earrings are noted as 6mm x 8mm. Opalite, a material sometimes used as an opal substitute, is described as a faceted teardrop stone, approximately 0.375in x 0.5in in size. It is important to note that opalite is not a natural opal but rather a man-made glass.
Opal in Jewelry and Modern Applications
Opal is frequently incorporated into jewelry, particularly earrings and necklaces. One example detailed in the sources is a pair of 24k gold vermeil sterling silver dangle earrings featuring a natural faceted pink opal. Another example is an opalite necklace with an 18K gold-plated stainless steel or 14K gold-filled chain, which can be personalized with a hand-stamped leaf charm.
The sources also mention the use of pink tourmaline as an October birthstone, set in 925 silver with 18k gold plating. The chain length for this necklace is 42cm, with a 2cm extension. The stones used in this necklace are noted to have minimal color variations due to their unique shape and color.
Symbolism and Metaphysical Beliefs
Opal is associated with a range of positive attributes, including faithfulness, confidence, hope, and innocence. It is considered a stone that inspires love and happiness. Historically, it was believed to grant wisdom and protect against disease. The association with Zeus’s tears in Greek mythology further reinforces its connection to divine protection and positive energy.
The concept of birthstones being “doorways to understanding yourself” is presented, suggesting that aligning with a birthstone’s qualities can offer insights into one’s personality. The stone’s connection to seasonal change and diverse color, as representative of October, further enhances its symbolic significance.
Care and Cleaning
The provided sources do not offer specific care instructions for opal. However, given its composition and the general recommendations for gemstones, it is advisable to avoid harsh chemicals, extreme temperatures, and abrasive materials when cleaning opal jewelry. Gentle cleaning with a soft cloth and mild soapy water is generally recommended.
