This is a gorgeous cab made from fossil agatized coral from Indonesia. Please don't worry about the harvesting of this stone harming ocean coral beds. That horrible practice involves a different kind of coral altogether. These are dead millions of years ago and now on the jungle floor. Agate has replaced the coral and now they are just chunks of cool rocks. This is a larger round cab in an elegant ivory color. It is not a shade we often see in this material. And we won't be seeing much more as the deposit is depleted.
