Australian Dark Opal 1.99ct. Loose set in Unset 10x8x5mm Classified by the Opal industry as Natural Opal Type 1 - White (or "Light") Opal is defined when the Opal is presented in one piece in its natural state apart from cutting or polishing, and is of substantially homogenous chemical composition and has a N7-N9 Body Tone. Light Opal is found in Coober Pedy in South Australia and is also found in more limited quantities in Andamooka and Lightning Ridge. Natural Australian Light Opal is pure natural Opal without any internal impurities and displays untreated natural colour. (Ethiopian Opal often looks like Light Opal however Ethiopian Opal is treated with chemicals, dyes and smoke to give the colour. Australian Opal is completely natural and far more valuable). Natural Gem Light Opal often displays 'Pinfire' and 'Rolling Flash' Patterns, but can also display the rare and porecious 'harlequin' pattern. When a Light Opal is 'transparent' it is sometimes called "Crystal" Opal. This Opal does not however have a 'crystaline' structure, and is not synthetic but pure natural Opal without any internal impurities and displays untreated 100% natural colour. https://vimeo.com/402071422
