I think that the Mr. Wizard answer would be to weigh the ring, then stick the ring in a full glass of water and measure the volume of water that spills out. Dividing the weight by the volume, you'd have the density of the ring, which you could compare to the density of pure gold.
Or you could take it to a jeweler at the mall and ask them.
