Also known as 'milk' or 'milky' opals, Australian white opals are distinguished by their pale white or light body tone, indicated in the below chart under "light opal". As with any kind of opal, white opals can display any colour of the spectrum in a beautiful play colour.
White opals are much more plentiful and common than other kinds of opal like black opal and biulder opal. Often white opals will have white potch (colourless opal) left on the back of the stone, however sometimes the entire stone will consist of colourful opal.
Because of their pale body tone, white opals generally have less vibrant colour than boulder opals and black opals. They do not have the advantage of having a dark or black background which enhances the stone and makes the opal color stand out.White opals are found in south australia in the major opal fields of coober peady, andamooka, and mintabie Find out more about these places in our article on the australian opal fieald.
