Relaxation For a Moment

There are those Asian Jade been found under the ocean made out of Coral.
Not these types of cause. I have heard they do combine the stone with it's outlook of what the above looks alike, I wonder how does those creative hands of Jewelery designers been studied.
Creativity are something without a boundaries, you can never get what in there at least you are the Art of it(project). I am admire those who searching under the ocean of treasures secretly, and legally. Ever since the movie "Titanic " ocean are deeper than the globe.
The picture above must had taken the photographer a couples of hours of Art! The moon might be the reflection by the assistant with mirror ? I assumed;)
Are those multi colored stone as coral jade?
