Known for the iridescence and the amazing colours that come from them as they diffract light. Depending on the conditions in which the stone forms, they can be transparent, translucent or opaque with a black, white or almost any other colour background.
Black opals are considered to be the rarest of opals, with white and grey being the most common. We sell both naturally mined opals and lab-grown stones, the product description of item will inform you when a stone is lab-grown.
We have a selection of unset natural and lab-grown stones, if you would like to have a custom piece designed and made, please do get in touch with us.
