Joe Ga took out the black diamond necklace, which was the "information fee" left by 'Medic Officer Bird' when he packed up and left without a word.
One of the diamonds, which was of relatively good quality, had been fashioned into a ring by Joe Ga himself and presented to Nis.
Another one, with obvious cracks in it, had been turned into a necklace by Joe Ga.
Somehow, after the processing, this diamond with multiple cracks would reveal an ink wash painting when light shone through it.
The ink painting of "Fishing Alone in the Cold River Snow" against a black background and white light, its value probably only appreciated by people from China.
Joe Ga initially intended to give the necklace to his brother, suggesting he keep it for the girl he loved, but now that Tong Tong's mother had become his family's benefactor, there was no need to pass it on.
