Revered throughout history for its beauty and believed metaphysical properties, the opal is a gemstone steeped in lore and symbolism. This article delves into the history, geological origins, gemological characteristics, and cultural significance of the opal, drawing exclusively from available sources.
History and Lore
The opal has a rich history, though specific dates regarding its initial discovery are not detailed in the provided sources. However, its enduring appeal is evident in its association with various positive attributes. The opal is described as a “soother of sadness & envy,” and is considered “the stone of luck.” Sources indicate the opal is also known as “the most powerful of healing stones, the stone of hope, [and] the stone of great achievement.”
Throughout time, the opal has been valued for its unique optical phenomenon. The sources highlight its association with creativity, inspiration, and transformation. This symbolism makes it a particularly meaningful gift for those born in October, representing love and affection.
Geological Formation and Sources
The formation of opals is a fascinating geological process. According to the provided materials, opals were formed “many millions of years ago, when a combination of silica and water flowed into cracks and spaces in the ground.” This silica-rich solution gradually hardened and solidified, resulting in the formation of the opal.
Currently, opals are sourced from several locations worldwide. Australia is prominently mentioned as a significant source, alongside Ethiopia, Brazil, and parts of the United States. The sources note the wide range of colors found in precious opal, spanning clear, white, gray, red, orange, yellow, green, blue, magenta, rose, pink, slate, olive, brown, and black. The most rare and valuable opals are those displaying reds against a black background, while white and green varieties are more commonly found.
Gemological Properties
The provided sources offer limited detailed gemological data, but some key properties can be identified. Opals are typically small, with genuine opal stones measuring approximately 3-4mm in size in some jewelry pieces. They are often cut and polished to enhance their play of color.
The sources indicate that opals are relatively delicate gemstones, requiring careful handling to avoid chipping. While a specific Mohs hardness scale rating is not provided, this fragility suggests a moderate hardness. The materials also mention the use of both natural opals and lab-created opals in jewelry. Some jewelry features “precision-cut crystal cubic zirconia” designed to mimic the appearance of opal.
Jewelry is commonly crafted from 14-karat gold, sterling silver, or 14k gold filled materials to showcase the opal. Chain lengths vary, with options including 16", 18", and 18-inch options. Pendants can be designed to be removable, allowing for customization with other birthstone pendants.
