At MARLII LAB, we are committed to creating jewellery of the highest quality. Our warranty policies are designed to ensure your satisfaction and the longevity of your treasured pieces.


Engagement and Wedding Rings:
Every MARLII LAB engagement and wedding ring is covered under a lifetime warranty upon presentation of a valid proof of purchase.

Ready-to-Wear Jewellery:
Our ready-to-wear jewellery comes with a three-year warranty from the date of purchase, as long as you can provide a valid proof of purchase.


Within the applicable warranty period, if your jewellery requires repair due to a manufacturing fault, we will provide a full repair and servicing at no charge. To initiate a warranty claim, please use our online repair portal.

Please note that manufacturing faults do not include damage due to general wear and tear, tarnishing, oxidation, fading of plating, broken chains, scratched or marked stones, or bending of rings or earrings. These issues are considered normal wear and tear and are not covered under our warranty.


Even after the warranty period has expired or if you cannot provide proof of purchase, we are dedicated to ensuring your jewellery remains beautiful for years to come. We offer repair services for the lifetime of your piece for a nominal fee. To arrange a repair, please use our online repair portal, where you will be able to submit your piece for assessment and receive a quote for the repair cost.


Our warranty is in addition to your rights under Australian Consumer Law. MARLII LAB adheres to all consumer guarantees as outlined in the Australian Consumer Law. For more information on your consumer rights, please visit the Australian Consumer Law website.


We are happy to assess any MARLII LAB product and offer cleaning and advice on how to maintain your precious jewellery. Regular maintenance will help preserve the beauty and longevity of your pieces.

Thank you for choosing MARLII LAB. We are here to ensure that your jewellery continues to bring you joy for many years to come.
