Ivory is illegal in many parts of the world because elephants are an endangered species.

I don't think that the artwork is extremely expensive, but not cheap either.

Ivory is so precious because it is now illegal to bring ivory into the Western countries. Ivory comes from the tusks of elephants and Western countries are trying to stop the over abundance of killing elephants just for their ivory tusks.
They crushed all of that ivory to make sure that no one could profit from it, and to try to protest the killing of animals (like Elephants) in order to acquire ivory. There are different opinions about whether crushing ivory will actually do any good, or just raise the price for it on the black market, but the event was well-intentioned.

The price of ivory can vary widely based on factors such as origin, quality, and legality. However, the illegal trade in ivory is a major concern and contributes to the decline of elephant populations.
