The Captivating Color Play of Dramatic Black Opal
Black opal, a gemstone with a mystical aura and breathtaking beauty, is one of the rarest and most sought-after gemstones in the world. Unlike any other gemstone, black opal boasts a captivating color play of blue, green, red and orange, set against a dark and dramatic background, creating an alluring, mysterious effect that’s unrivaled in the world of gemstones.
Black opal is a member of the opal family, a group of minerals made up of hydrated silica. Featuring a chemical formula of SiO2·nH2O, black opal is created when silica gel seeps into cracks and crevices in the Earth, where it solidifies and forms opal.
However, unlike the other members of the opal family, black opal has a dark, almost black background that enhances the colors of the stone, making them appear more vibrant and intense. The rich play-of-color in black opal is a result of light passing through tiny spheres of silica, creating a mesmerizing effect that’s both mysterious and enchanting. The colors of black opal are not just on the surface, however. They penetrate deep into the stone, giving it a three-dimensional quality that’s unmatched by any other gemstone.
Black opal was first discovered in Lightning Ridge, Australia, in the late 19th century. The unique combination of geological conditions and mineral content in certain areas, such as Lightning Ridge, has led to the formation of some of the world’s most magnificent black opals. Today, black opal can also be found in other parts of Australia, as well as Mexico, Ethiopia and Nevada.
Black opal’s value is determined by a combination of factors, including its color, clarity and size. The most valuable black opals have a deep, rich body color and a vivid play-of-color. Also, the larger the stone, the rarer it is, and therefore, the more valuable it becomes. A hardness of 5.5 to 6.5 on the Mohs scale, black opal’s durability and hardness also contribute to its value, making it a popular choice for jewelry, especially for statement pieces and unique designs that showcase its captivating color play. However, black opal is relatively soft compared with other gemstones and requires careful handling.
In folklore and history, black opal has been associated with many different meanings and beliefs. The ancient Greeks believed that opals gave their owners the power of foresight and prophecy, while in the Middle Ages, it was believed to bring good luck and protect against evil. In modern times, black opal is often associated with creativity, inspiration and emotional healing.
Some of the most significant and famous black opal stones and jewelry include the “Virgin Rainbow,” a magnificent black opal from Lightning Ridge that’s estimated to be worth more than $1 million (see image above). This stunning gemstone is a kaleidoscope of color, with vivid hues of blue, green, yellow, orange and red set against a dark, almost black background. Its intricate play-of-color is reminiscent of a mesmerizing rainbow, with each hue blending seamlessly into the next.
Weighing approximately 72 carats, its size only adds to its captivating beauty. The stone is cut in a free-form shape, which showcases its unique color play and allows the stone to shine from every angle. The opal is also notable for its transparency, which is rare for black opals. When light passes through the stone, it illuminates the colors and creates a mesmerizing effect that is truly awe-inspiring.
There’s also the “Royal One,” a 306-carat black opal that was once part of the collection of Queen Elizabeth II. In 1954, the Queen visited Australia on a royal tour and, during her visit, she was gifted the “Royal One” black opal by the Governor-General of Australia. The Queen was reportedly so taken with the stone that she had it mounted into a brooch, which she wore frequently.
Weighing an impressive 306 carats, this opal is one of the largest and most valuable black opals in the world. The stone was discovered in 1905 in Lightning Ridge, and it was initially owned by a miner named Jack Phillips. The “Royal One” black opal boasts a dark, almost black background that enhances its vibrant and intense play-of-color. The free-form stone is predominantly blue and green, with flashes of red and orange, creating a mesmerizing effect that’s both mysterious and captivating. The colors of the stone seem to shift and change with every movement, making it impossible to take your eyes off of it.
Black opal is typically cut into cabochons, a smooth, domed shape that highlights the stone’s color and play-of-light. The typical carat weight of black opal ranges from a few carats to several hundred carats, with larger stones being extremely rare and valuable.
Today, black opal can be found in various forms of jewelry, including earrings, pendants and rings, and it continues to captivate people with its mysterious and mesmerizing beauty. Whether you’re drawn to its unique color play, its rarity or its association with creativity and emotional healing, black opal is a gemstone that’s sure to leave a lasting impression.
