The platelets form a working surface (20,21) which is complementary to the required shape. The platelets (28) adjoin one another and present a substantially continuous surface. Each platelet is made of a composite material having a composition comprising silicon carbide, and a material selected from the group comprising gemstone powder, and synthetic diamond powder.
