Qiao Zhiyi leaned in for a closer look and indeed saw the shallow letters "SLT" engraved inside the gem.
She hadn't expected that the brooch originally served as proof of Shi Lanting's identity.
"What's wrong?" Bai Yue returned the brooch to her, a bit curious.
Qiao Zhiyi took it back, "Is this one of a kind?"
"Of course. I remember her mother also had one of the same style, just a different gem color. This brooch seems to be the work of some foreign jewelry master; each color corresponds to one piece. They have a circle of their own, and they meet occasionally. They are all either wealthy or noble, not something ordinary people have."
Qiao Zhiyi felt more confident now.
"Thank you."
"Why are you suddenly asking about this?" Bai Yue glanced at the brooch, "You didn't steal it, did you?"
Qiao Zhiyi didn't expect her to ask such a question.
