The loose doublet opal offered by Australian Opal Cutters does not include a setting. Every opal jewelry and loose item from them is covered by an international warranty. If you want any changes, upgrades, or color requirements for your opal, please add a note during checkout, and it will come with an additional charge. They can modify or upgrade any item and its Opal design. Please note that opals have a distinct play of color that is difficult to capture precisely on camera, so the item received may not be the same as the one presented online.
