The latest installment in the battle between a cruise ship passenger and a Doral-based cruise line over a diamond worth nearly $5 million has handed a victory to the passenger.

The Third District Court of Appeal denied Starboard Cruise Services’ motion for attorney fees from former passenger Thomas DePrince in a ruling issued Wednesday. The two parties have been locked in litigation for several years over DePrince’s purchase of a 20.64-carat diamond for only $235,000 in 2013.
