This is a beautiful pair of modernist earrings-studs created in Europe around the 1970-1980. They were masterfully crafted in oval shapes with geometric patterns in solid yellow gold of 18 karats with textured finish. They are mounted with very fine matching pair of natural precious black opals and fitted at the reverse with gold posts for pierced ears and butterfly backs for comfort.

Australian Black Opals

These kinds of opals are the most valuable and widely known type of opal. Black opal is characterized by a dark body tone which can range from dark grey, blue, green to jet black. Unlike ordinary opals, black opals have carbon and iron oxide trace elements present, which cause the unusual darkness of the stone. Because of their dark body tone, the rainbow colors in a black opal stand out much better than lighter opals. This vibrancy of colour makes black opal the most valuable form of all opals. Black opals are mostly mined in Lightning Ridge, in northern New South Wales. Lightning Ridge is famous for the black opal and hundreds of millions of dollars’ worth of black opals have been found there. In 2008, the black opal was named as the ‘gemstone emblem’ for New South Wales. Black opals have also been found at Mint Abie in South Australia.
