Opal is silica's most spectacular performance — a mineral that diffracts white light into every wavelength simultaneously, producing a phenomenon called 'play-of-color' that no other gem can replicate.
This 1.35 cts Opal of Grey with Play of Colour -5 moderately strong- strong hue from Australia was selected for the Skyjems Archive not as an afterthought, but as a deliberate acquisition. It is entirely unheated and untreated — a distinction that places it in the top fraction of the global Opal supply and is the single most important value driver in the collector market. Australia's Lightning Ridge produces the world's finest black opal — a geological phenomenon so concentrated in optical power that fine specimens rank among the highest per-carat gemstones on the market.
