Opal is a fascinating and mesmerizing gemstone known for its iridescent play-of-colour, which displays a spectrum of colours when viewed from different angles. It is one of the most unique and sought-after gemstones in the world. Here are some key features and information about Opal:
Colour and Play-of-Colour: Opal is valued for its unique play-of-colour, which is a captivating display of rainbow-like hues that shimmer and change as the gemstone is moved. The play-of-colour is caused by the diffraction of light by silica spheres within the gemstone. Opals can also come in various base colours, including white, black, blue, green, and orange.
Formation: Opal is a hydrated amorphous form of silica and is formed from the gradual deposition of silica gel in rock fissures and voids over millions of years. The silica spheres in the gel are responsible for the play-of-colour.
Hardness: Opal has a relatively low hardness, ranging from 5.5 to 6.5 on the Mohs scale. This makes it more susceptible to scratching and chipping compared to other gemstones like diamonds or sapphires. Opal requires gentle care and protection.
Origin: Opals are found in various locations around the world, including Australia, Ethiopia, Mexico, Brazil, and the United States. Each region may produce Opals with distinct play-of-colour and characteristics.
Astrological Significance: In some belief systems, Opal is considered the birthstone for those born in October. It is associated with traits like hope, innocence, and purity.
Healing and Metaphysical Properties: Opal is believed to possess metaphysical properties, such as promoting creativity, enhancing intuition, and supporting emotional healing. Different colours of Opal are associated with specific metaphysical attributes.
Jewellery: Opals are used in various types of jewellery, such as rings, necklaces, earrings, and pendants. Opal jewellery is highly prized for its unique beauty and the mesmerizing play-of-colour.
Due to the unique nature of Opal and its sensitivity to moisture and temperature changes, it requires special care and should be protected from extreme conditions. It’s essential to buy Opals from reputable sources to ensure their authenticity and quality. When purchasing Opal jewellery, consult with a knowledgeable jeweller who can provide you with information about the gemstone and proper care instructions to maintain its beauty and longevity.
