A set of dress cuff links and studs

A set of dress cuff links and studs, the cuff links each set with four cabochon sapphires and centred with a circular cut diamond in white gold. With three matching slightly larger studs and two studs with larger cabochon sapphires. The cuff links white gold, the studs platinum and white gold. And a cased set of dress studs with hexagonal black onyx sections, each centred with a small diamond within tied reeded borders. And two similar small studs. And an additional black onyx set gold stud.
