Gold and silver rings. They are old. 3.0g (gold), 3.8g (silver). The gold one has a structure that allows for size adjustment (?). There are hallmarks for pure gold and pure silver, but they are unverified. Returns are not accepted to prevent substitution. As they are old, there are scratches and stains. They will be delivered as is, without cleaning. Measurements were taken with a kitchen scale, so there may be some error. Please understand.
