We can not gaurantee plating. The level of gold plating on Lilywho items is top class and will last a long time with care, however it is still plating. Gold plating will wear off over time and will be damaged badly by perfumes, chlorine, cleaning dips or any other chemicals. If you want something to last a lifetime, please buy our 9ct or 18ct gold items, in our fine Jewellery section.
