As October arrives, so does the opportunity to celebrate one of the most mesmerising gemstones: The opal.
Opals are formed from silica gel that fills cracks and cavities in rocks. Over time, this gel hardens to create the opal, the play of colour results from light diffraction through the stone’s silica spheres. Australia is the leading source of opals, known for its rich deposits of these gems. You can find this gemstone in Ethiopia, Mexico, Brazil, and the United States too. The largest opal ever discovered is the ‘Olympic Australis,’ it has remained uncut and in its natural state, weighing a massive 17,000 carats.
History of Opal
Opal has been admired for centuries and holds different meanings in various cultures. The ancient Romans valued opals as symbols of hope and purity, believing they offered protection from illness. In medieval Europe, opals were seen as good luck charms, thought to contain the powers of all gemstones because of their colourful iridescence. However, in the 19th century, opals gained a reputation for bad luck, partly due to the novel Anne of Geierstein by Sir Walter Scott. In Aboriginal Australian legend, opals were believed to hold the spirit of their creator, who touched the earth and turned stones into glowing rainbows. Throughout history, opals have been surrounded by both positive and superstitious beliefs, adding to their mysterious charm. Opals are still celebrated to this day for their unique beauty and remain a popular choice for October birthstone gifts, symbolising creativity and emotional enrichment.
Types of Opal
When it comes to opals, there are two main types:
Precious: This type displays a spectacular play-of-colour and includes varieties such as black, boulder, and crystal opal.
Common: Lacking the play-of-colour seen in precious opals, common opal varieties include pink, blue, and fire opal.
Opals continue to be a favourite in the world of fine jewellery. Their unique play-of-colour and individual characteristics make each piece special, whether it’s a ring, necklace, earring, or bracelet.
