This is a pair of cufflinks set with an array of precious stones laid out in a precise grid-like pattern. You're unable to find three in a row of the same color -- looks like all of the rows of three mysteriously disappeared.
(In-game plural: pairs of bejeweled cufflinks)
- The description about not finding three in a row of the same color is a reference to the puzzle game Bejeweled.
