摘要： A process of forming a non-optically detectable authentication marking (110), includes the step of: applying a marking at a surface of a diamond (200) using a focused ion beam (FIB) writing process so as to provide a non-optically detectable authentication marking (110) which is formed by alteration in the optical characteristics of a portion of the diamond material at the outer surface of the diamond to form a marked portion; wherein the marking is optically invisible, and wherein the marking is viewable by an imaging method which provides an observable contrast between the portion of the diamond having altered optical characteristics and the non-marked portion of the diamond. The marking process can assist in the prevention of the counterfeiting of precious articles, and be of assistance in the incident of theft. A marking, a diamond, a process of viewing a marking on a diamond are further disclosed.

摘要： A process of forming a non-optically detectable authentication marking (210,320, 410,535) in a diamond (200,300). Authentication marking (210,320,410,535) is formed adjacent the outer surface of an article formed from a diamond material having intrinsic optical centers. Method includes the step of applying an image of predesigned authentication marking(210,320,410,535) to a region (201,310,530) of a diamond (200,300) at or adjacent the surface of the diamond (200,300) by way of a direct laser writing; wherein the fluorescence background of the diamond material from intrinsic optical center is suppressed by authentication marking(210,320, 410, 535) under fluorescent imaging, such that the non-optically detectable identifiable authentication marking (210,320,410,535) is viewable against the fluorescence background at the region (201,310,530) of the diamond (200,300) where the authentication marking (210,320,410,535) is applied.

摘要： A process operable uses a computerized system for displaying an article from a set of wearable articles or accessories. The article is displayed based upon a correlation between data indicative of features of mental impression of an article and the displayed article, and the computerized system includes a touch sensitive input device, a process module and a visual display module operably interconnected together via a communication link. The process includes the steps of (1) entering via a touch sensitive input device a first visual representation indicative of at least a portion of a mental impression of an article, wherein the first visual representation is a two-dimensional representation in a first predetermined viewing plane; (ii) in a processor module, comparing during step (i) data derived from input of the first visual representation and other data sets; and (iii) displaying on a visual display module a visual representation of at least a first article corresponding to the other data sets.
