You can find some in the Caribbean. Since that's the case, it's generally a bad idea to obsess over it, and any other caribbean coral. Not only are they illegal to collect, they are illegal for a pretty good reason.
A good, valid case can be made for collecting coral from Pacific reefs, which cover a much more vast area than the Caribbean. The Caribbean is also surrounded by dense population, and not in great shape overall.
It might be possible to track down a piece of whatever caribbean coral you obsess over, but it's a bad idea. Stick with Pacific hard corals.
