The investigation began when the provincial Economic Police Division noticed several online stores heavily promoting jewelry modeled after world-renowned luxury brands.

These products were marketed to consumers as "high-end handcrafted pieces," "brand-standard designs," and "custom-made items." To build consumer trust, the sellers used professional photography, hosted livestream sales sessions, and offered direct customer consultations.

Police observed that sales of this so-called premium jewelry were surging, bringing in substantial revenue despite glaring irregularities regarding where the products actually came from.
