Fairy opal is basically a sandstone base rock impregnated with tiny pieces of precious opal. Because the sandstone is very pale it is often difficult to see the play of opal colour in the stone and hence a method of darkening the sandstone background was developed so the colour of the opal could be seen.
These stones have been treated or'cooked' in order to darken the base to bring forth the beautiful opal colour. The treatment does not change the opal or stone in any way other than darkening it to give it an enhanced colour flash. The method used is to cook the stones is heating in oil. The oil penetrates the pores of the sandstone and the heat burns the oil then carbonises it thus darkening the stone. Please note: This opal is natural and it is common for natural stones to contain inclusions and/or fractures.
All possible care is taken to capture the true and natural image of the opal and pictures are not enhanced in any way, besides enlarging and cropping. Please be aware that there may be some loss, change or distortion of colour due to the difference of computer monitors or smart device screens.This unfortunately cannot be avoided.
