The finishes applied to some DoDo jewels are created through specific surface treatments. Over time and with normal wear, it is natural for these treatments, such as rhodium plating or sandblasting, to change from their original appearance, gradually revealing the natural metal surface underneath.
To help preserve these finishes for as long as possible, avoid using polishing cloths, jewellery cleaning cloths, or other abrasive products on treated surfaces. Contact with cosmetics, perfumes, soaps, detergents, chlorine, and chlorinated water should also be avoided, as these substances may affect the finish over time.
In many cases, and in accordance with DoDo's after-sales service policies, surface treatments can be restored through professional servicing. The final result will depend on the specific treatment involved and the overall condition of the jewel.
