Colours may vary. These earrings are made from Natural Australian Opal in a 'Triplet' form, meaning the layer of Opal in this beautiful pair is protected by a window of quartz and black plastic, which also enhances the colour of this product. Colours may vary from a blue/green tinge to a blue/red, showcasing their variety and natural beauty. It is important to avoid water exposure and never submerge your Opal in water, as prolonged exposure may lead to a foggy appearance which cannot be reversed. Avoid any harsh chemicals and cleaners, as these will damage your Opal jewellery. To clean your Opal, simply wipe with a damp cloth and pat dry with a soft towel.
