This is a mixed lot of 3 x natural Ethiopian Welo Opals, which is shaped and polished.
They are all freeform, with the largest piece approx. 11mm by 9mm by 3.5mm thick, the smallest 7mm by 6mm by 2mm, with a total carat weight of 4.40.
These opals all have colour and show the different ways they present themselves, from cream to pale brown to crystal. They are not quite good enough to be included in fine jewellery, but could be used in costume jewellery or kept as interesting mineral samples.
