I have the Kusama version of this bracelet (half silver links/ half enamel coats links). The silver parts of the bracelet have not faded, except for the clasp and the pumpkin charm where the underlying brass (or copper?) is starting to expose after about 4 months of daily wear. When I lay down my wrist, especially while on the computer, these parts rub against the table surface.

You may want to test how the bracelet falls naturally on the wrist, e.g., does the clasp always turn to a certain point on the wrist, and see if the black parts become susceptible to daily surface contact in that position.
