Few things are so rare as the black opal. And you need to find the most precious of them all. Rusty has been able to track it to an area on the sea floor. It’s in one of the shipwrecks there.
The task in the "Old Shipwrecks" location is part of the "My Precious Opal" quest. In order to finish this quest, Diggy needs to also clear the repeatable location "Opal Room".
