Not as good as platinum,

It will get dark after a long time,

You've been cheated.

I suggest you go to the store for identification.

It's not platinum, it's another kind of gold, which is not as valuable as platinum.

Palladium is also a good choice as jewelry, but platinum is more popular at present, which is related to the trend, not to say that platinum is better than palladium. In fact, the difference between the two is not too big. Palladium and platinum originally belonged to a family of elements.
