Most white gold is plated to give it the bright white color. There is one white gold that I know of which needs no plating which is called "X1 White Gold". To clean your white gold plated jewelry a solution of half water and Mr. Clean with a small amount of ammonia can be used. Soak for 15 seconds then rinse with water and dry.
Yes, gold plating uses real gold. The layer of gold, which is applied using electrochemical deposition techniques (electroplating), is usually only a few microns thick. This layer of gold adds beauty to items, makes them more reflective, improves their electrical and thermal conductivity, and (probably most importantly) makes them very corrosion resistant. It should be noted that the actual value of the gold on a "standard" application like a circuit board edge connector is only a buck or two. It's usually only cost effective to recycle gold plated electronics stuff in bulk. It is, however, important to recycle as many things and as much of the non-useful things we have as it is possible to do. The landfill is not the best place for stuff like that.

8-3-11>>> I know they sold on TV for $19.95 + $7.95 S & H, but this stuff has no numismatic value at all. The only value it has is to some one that wants it. Even with gold at $1,666.60 per ounce, this piece likely only has 10 cents worth of gold on it.
