Precious Opals: The Enchanting Rainbow
Precious opals are the most well-known and sought-after type of opals. These opals display a captivating play of colours, including flashes of red, green, blue, and yellow. The play of colours in precious opal results from light interacting with microscopic silica spheres within the stone. The arrangement and size of these spheres determine the colours observed.
One of the most prized varieties of precious opals is the black opal, which features a dark body colour that enhances the vibrancy of the play of colours. On the other hand, Boulder opals form in ironstone, resulting in a unique and striking combination of opal and host rock.
Fire Opals: The Vibrant Flames
Fire opals are renowned for their intense orange, red, and yellow hues, reminiscent of a flickering flame. Unlike precious opals, fire opals lack the play of colours. Instead, they exhibit a warm and vibrant glow that captures attention. Fire opals are typically transparent to translucent, allowing light to pass through and illuminate their rich colouration.
These opals are primarily found in Mexico, and they are often used in jewellery to add a pop of fiery brilliance. Fire opals are believed to symbolise passion, creativity, and vitality.
Boulder Opals: Nature’s Masterpiece
Boulder opals are unique in their composition, as they form within the cavities of ironstone boulders. The ironstone acts as a natural backing for the opal, creating a striking contrast between the vibrant play of colours and the earthy matrix. This distinctive combination gives boulder opals a rugged and natural appearance.
Boulder opals can display a wide range of colours, including blues, greens, and even flashes of red. Their appearance varies greatly, with some intricate showcasing patterns and others featuring broad patches of colour. Each boulder opal tells a story of its own, with a truly mesmerising beauty.
Crystal Opals: The Translucent Elegance
Crystal opals are highly regarded for their transparency and clarity. They have a transparent to semi-transparent body, allowing light to pass through and illuminate the play of colours within the stone. Crystal opals can exhibit a full spectrum of colours, ranging from soft pastels to vibrant hues.
These opals are cherished for their elegant and ethereal appearance. When set in jewellery, crystal opals create a delicate and enchanting effect, as if the colours are floating within the stone.
Ethiopian Opals: The New Discovery
Ethiopian opals are a relatively new addition to the world of opals, but they have quickly gained popularity for their unique characteristics. They often exhibit a vivid play of colours, with flashes of red, green, and blue. Ethiopian opals are known for their transparency and can display an impressive level of brightness and fire.
In conclusion, opals come in various types, each with its own distinct qualities and allure. Whether you are captivated by the mesmerising play of colours in precious opals, the fiery brilliance of fire opals, or the unique combination of opal and ironstone in boulder opals, there is an opal engagement ring to suit every taste. Crystal opals and Ethiopian opals also offer their own unique beauty with their transparency and vibrant colours.
