Never heard of such a thing?, a 'crystal set' is (these days) a simple tuned circuit followed by a germanium diode detector, it's AM only, requires a huge outdoor aerial, and only receives close strong signals. Originally it used a tuned circuit and a piece of 'crystal', which was galena (not sure about the spelling?), and you used a 'cats whisker' (fine springy wire) to locate a sensitive spot on the crystal.
Presumably your radio is a superhet with a PLL synthesiser?, which uses a quartz crystal as the reference frequency - however, in no way could it be called a 'crystal' radio. As for 'ceramic radio', again theres no such thing!.
