Australian Light Opal Ring set in 9K gold

We're delighted to present our elegant Australian Natural 7x5mm Light Opal Ring in Size L, set in 375 9K White Gold. This ring features a Natural Opal Type 1 - Australian Light Opal, which is defined by the Opal industry as an opal presented in one piece in its natural state, without cutting or polishing, and with a substantially homogenous chemical composition. Genuine Natural Australian Light Opal is not commonly found in all of the Australian Opal fields, but predominantly from Coober Pedy in South Australia. This opal is a hydrated amorphous form of silica SiO2nH2O, consisting of spheres of silicon dioxide molecules arranged in regular, closely packed planes. It has a white base tone with elements of Magnezium Oxide present within the pure hydrated silica SiO2nH2O. This precious opal displays a mesmerizing interplay of internal colours, and despite being a mineraloid, it has an internal structure. At microscopic scales, precious Opal is composed of silica spheres that range from 150 to 300 nm in diameter in a hexagonal or cubic close-packed lattice. To make your experience with us even more special, all our Australian Opal Cutters Jewellery and Loose Opal items come with our international warranty. We invite you to let us know during checkout if you would like to add any modifications or changes or request a specific colour requirement for your Opal. For an additional charge, we are happy to change or upgrade your opal or even personalize the design of any item you choose. Please note that the item you receive may not exactly match the item shown online, as opals have a living play of color that can be challenging to capture on camera.
