The opal is backed by Australian Black Opal potch or Boulder Opal Potch, ensuring both layers have the same coefficient of thermal expansion and are guaranteed for life against delamination. Rest assured, our opals are guaranteed free of dyes and artificial color. Every jewelry piece and loose opal item from Australian Opal Cutters comes with an international warranty for your peace of mind. During the checkout, feel free to send us a note if you wish to make modifications, request changes, or specify color preferences for your opal. For an additional charge, we offer the option to upgrade your opal or adjust the design of any item in our collection. Please note that the opal you receive may exhibit variations in its living play of color, which can be challenging to capture accurately in photos."
