Both Palladium and Platinum will indicate Karat Gold if tested. Platinum

jewelry is usually traded at a higher price than Gold jewelry, so Platinum is

seldom marked as Gold. Palladium, however, is one-quarter to one-third the

price of pure Gold, so it should be noted that pure Palladium might read as

medium Karat gold. Palladium prong settings are sometimes soldered into

diamond solitaire White Gold rings. If Palladium is suspected, it is easily

distinguished from Gold, as nitric acid will quickly turn Palladium dark, Gold is

not affected in this way.
