I think it all depends on who sells it. I have heard it both ways
myself. Since I have not had an opportunity to see it harvested and
track it to the lfs and weight it, I just go by feel and size and gut
feeling......I know one time many many years ago we pulled liverock
from the caribean islands on a dive trip, long before it was illegal
or inappropriate to do so, and that rock had more of a crystaline
surface and when broken, it would have lots of smooth slick surfaces.
It was almost as if the rock was comprised of quartz instead of
calcium based products.

Interesting. When I was shopping for live rock a while back, one site that was
selling Caribbean rock claimed that it was one of the *least* dense varieties.

In any case, I wound up buying something called "Tonga Deep."
