Abstract:
A lapidated stone for articles of jewelry is described, including a table and comprising at least two complementary stones (1, 2) of different colours, each having a table surface (3, 4) and a junction surface (5, 6). On placing the complementary stones together, their table surfaces (3, 4) complete the table (7) of the composite stone and the junction surfaces (5, 6) are superimposed on each other so as to produce a composite stone having a complementary and continuous lapidation giving the appearance of a single stone. A process of manufacturing the composite stone is also described, comprising the steps of: providing at least two non-finished complementary stones lapidated with respective table and junction surfaces; penning the two non-finished complementary stones together and then carrying out the finishing of the complementary stones together on the pen so that the final composite stone presents a complementary and continuous lapidation to give the impression of a single lapidated stone; and removing the stone from the pen, separating the complementary stones.
