Australian Light Opal Ring set in 9K gold

Embrace the natural beauty of Australian opals with our stunning Australian Natural 8x6mm Light Opal Ring, Size N, set in 375 9K Yellow Gold. This opal has been classified by the industry as Natural Opal Type 1 - Australian Light Opal, meaning it is presented in one piece in its natural state aside from cutting or polishing and is predominantly sourced from Coober Pedy in South Australia. It is a hydrated amorphous form of silica - SiO2nH2O - consisting of spheres of silicon dioxide molecules arranged in regularly packed planes and features a substantially homogenous chemical composition with elements of Magnesium Oxide present, giving it a white base tone. The opal's internal structure, composed of silica spheres approximately 150-300 nm in diameter in a hexagonal or cubic close-packed lattice, creates a fascinating display of internal colors. Our Australian Opal Cutters Jewellery and Loose Opal items are backed by our international warranty. During checkout, you can leave a message if you wish to make any modifications or have specific color preferences for your opal.
