This lot consists of 6 small opal doublets of various shapes, sizes and colours. The two drop-shaped ones are 1cm long and ca. 5 mm wide at their widest point, with one being ever so slightly slimmer than the other. The oval blue one is 8mm long and 6mm wide, the smallest, round one has a diameter of 5mm. The other round one, the blue one, is 6mm in diameter, and the grey oval one is 8mm long and 5mm wide. All display good, strong colours and are in excellent condition. Please observe that doublets should not get wet, since the water might get in between the layers and dull the colours (Read more about doublets on our website).
