Are the Olympic medals solid gold, silver, and bronze?
No they are not. It is hard to make anything useful out of solid gold since pure gold is relatively malleable and easy to bend. A large object made out of pure gold would not be very durable. It would not tarnish of course since gold will not rust/oxidize, but it would be likely to sustain physical damage. The olympic medals have stringent standards as to how they are made, but within those standards the host nation can vary the material. The chinese is the first olympics to use jade as a part of the medals. See the links below for details on the chinese as well as australian olympic medals…
