This is a job lot of 2 small opal doublets of similar sizes, shapes and colours. Doublets consist of a thin slice of natural opal, which is mounted upon an underlay of dark slate to bring out the colours and the sparkles. These two doublets have a grey background colour and display flashes of pink and green. They are 8mm long and 5mm wide with one of them being just a tiny fraction of a mm longer. But in an emergency they could perhaps be set into a pair of earrings, alternatively, they can just be used as mineral samples for display.
