The moment with the turquoise necklace exposes Grandcourt’s growing awareness of Gwendolen’s inner life. Daniel’s recognition of the necklace signals his understanding that it holds personal significance for her, but Grandcourt’s reaction is different. His contemptuous remark reveals his belief that Gwendolen’s emotions, and even her past, are trivial at best and manipulative at worst. Her attempt to stand her ground by insisting that the necklace is simply an old keepsake is a rare act of defiance, but it does little to shake Grandcourt’s control.
