Abstract: The invention relates to natural or artificial pearl in which one or more ornamental elements (4) are inserted in form of an inlay with or without a mount, wherein the outer visible top or ornamental side opposite the pearl of each inlay has a horizontal projection with a random contour and dimensions confined by the limits of the spherical surface and wherein the inner bottom side facing the pearl of each inlay is fitted with locking or anchoring means (20). Each inlay is lodged with positive-fit or at least substantially with positive-fit in an appropriately matching groove (6) (slot, cavity), locking and/or anchoring means being formed in the bottom and/or wall of said groove which interact with the corresponding inlay, preferably by positive locking according to the key-lock principle, and in or on which the inlay inserted into the groove is fixed in or on the pearl.
