From both Pirates of the Caribbean: Dead Man's Chest and the adventures of young Jack Sparrow novels aimed at young readers, viewers learn that Jack Sparrow made a deal with Davy Jones to resurrect the Wicked Wench from the depths, but upon doing so Jack re-christens the ship with the name The Black Pearl.
The Black Pearl was an infamous pirate ship, originally named the Wicked Wench. At one point it was sold and turned into a merchant vessel before turning back to piracy when it was re-christened. With sails as dark as a moonless night, and a hull painted to match, this legendary ship of the seven seas was every inch a pirate vessel. Built for action, this ghost ship could outsail any other sailing vessels. The Black Pearl was most notably captained by Jack Sparrow and Hector Barbossa.
Why does Jack rename the ship the Black Pearl? Where does the name "Black Pearl" originate and/or why did he choose to rename it? (I'm primarily interested in an in universe answer, but would accept an out of universe answer if no other answers can be found).
