Looks like the hollywood stunner chalice. It's a common chalice

Yup looks like the stunner to me.

Nope, not a Stunner. Look at the mouth structure. It is some kind of mycedium.

The Stunner is a Echinopora llamellosa which are usually very thin plating. The coral pictured looks fairly thick plating.
