Wiki said Zirconium is a silvery metal. Why do I get tons of pictures about white ceramic and diamond when I search zirconium??

Zirconium, the pure element, is a metal. Wiki's right... in most of cases.

Zirconium dioxide, also called zirconia, is a ceramic material when its normal purity. You may find ceramic knife in grocery store and thats zirconia. However, when the purity is high and made to specific crystal form, it can be transparent crystal, look like diamonds. Anyway, this is an artificial material and won't worth too much money.

Those are good answers. Calling the artificial gem a zirconium instead of a zirconia is a marketing error.

well the "diamonds" are large single zirconium dioxide (ZrO2) crystals - also known as cubic zirconia.

the white ceramic things are also ZrO2

Zirconium is a metal and an element.
