How do you find the jewel of life on endless ocean

Believe me, I know how. I have been trying to do the same for ages. First you need to uncover 90% of the map. Then you should get an email saying you've uncovered that much. Well, you do get the email if you have done it right. After that, go to the ruins and find the three heads that are made of rocks. You can find them at the co-ordinates of I5. My first thought was that they would be small, but they're actually quite big. In front of the middle head you should see a little shine. That means theres a treasure there! So go ahead an click it. This should give you the jewel of life. Once you have that, head back to the boat and go to the ship wreck. When your arrive, swim to the ghost ship and there should be this cut scene. You will then be taken to the grave yard, or the Ships rest. Once THERE swim to the very top of the front plane wing thing. You should see an Orca. Obviously befriend it. Then you have a new partner! Sorry, I kinda told you everything to do with the jewel of life x] By the way try your best not to be scared of the sharks that swim around the plane crash, I freak at that part.
