What does warranted 24 KT gold mean on a vase?

"Warranted 24 KT gold" on a vase indicates that the item is decorated or trimmed with gold that is guaranteed to be 24 karats, meaning it is pure gold without any alloyed metals. However, this usually refers to a gold plating rather than solid gold, as solid 24 KT gold would be impractical for everyday items. The "warranted" label suggests a promise of quality regarding the gold's authenticity and durability.
