Who is Gypsy from Sudden Fiction International: Sixty Short-short Stories and what is their importance?

The Gypsy in On Hope lives on Gibraltar and trains moneys to steal for him. One day, his most effective monkey returns to him with the Hope diamond, the largest diamond in the world, a part of the British crown jewels, and a cursed stone. The Gypsy sends it back to the visiting princess, but the monkey steals it again. He sends it back once more, and the monkey returns with it before dying, having been shot by a British guard. The gypsy swims out in the Mediterranean to dispose of the diamond, but it lands on a shark, who rises to the surface with the jewel on its dorsal fin. The story ends with the Gypsy, thinking a miracle has occurred, swimming towards the shark in earnest.
