The example faceted precious stone comprises a crown portion (C), a girdle (G), a pavilion portion (P) and a base B. The girdle is intermediate the crown portion and the pavilion portion and the pavilion portion is intermediate the base and the girdle. The crown portion comprises one table facet (TF) and a crown main facet tier that is intermediate the table facet and the girdle, the crown main facet tire consisting of N crown main facets (C1), N being a plural integer number. The pavilion portion comprises a pavilion main facet tier consisting of N pavilion main facets (P2), wherein the N pavilion main facets are radially distributed about a central axis to form a star pattern, the central axis extends through the base and is orthogonal to said table facet or a girdle plane defined by said girdle.

Abstract

An identifiable mark on a portion of a polished facet of a surface of an article and being identifiable by an optical magnifying viewing device, said identifiable mark comprising a nano-structure formed by a two-dimensional or a three-dimensional lattice of a plurality of discrete nanometer sized recessed or protruded entities, wherein said entities are arranged within a predefined region of said polished facet in a predetermined arrangement in relation to each other and such that an outer interface surface between the facet of the article and air is formed and an inner interface surface between the facet of the article and air is formed. Said predetermined arrangement of said entities is non-uniform and non-periodic arrangement, and wherein said entities are sized and shaped so as to cause optical scattering upon reflection of incident light and the distance from the inner interface surface to the outer interface surface is greater than the amplitude of the non-marked portion of said polished face. Upon reflection of incident light having one or more predetermined wavelengths by said lattice at a predetermined angle of incidence to said lattice, interference due to scattering of light from said lattice is induced such that said reflected light has a variation in intensity providing one or more local maxima of one or more wavelengths. Said mark is identifiable by way of an optical magnifying viewing device inclined at a requisite viewing angle such that a local maxima is detected.

Abstract

An ornamental assembly (10) comprises a first ornamental part (120) and a second ornamental part (140). The first ornamental part (120) comprises a first ornamental body defining a first arcuate portion, a first plane and a first arcuate surface on the first arcuate portion. The second ornamental part (140) comprises a second ornamental body defining a second arcuate portion, a second plane and a second arcuate surface on the second arcuate portion. The first ornamental part (120) and the second ornamental part (140) are joined at a hinge joint (130) and are relatively rotatable about a hinge axis (138) defined by the hinge joint (130) to move between a first configuration and a second configuration. The first arcuate surface and the second arcuate surface are in complementary abutment when the first ornamental part (120) and the second ornamental part (140) are in the first configuration. The first arcuate surface and the second arcuate surface are not in complementary abutment when the first ornamental part (120) and the second ornamental part (140) are in the second configuration.

Abstract

An ornamental assembly (10) comprises a first ornamental part (120) and a second ornamental part (140). The first ornamental part (120) comprises a first ornamental body defining a first plane and a first latching part. The second ornamental part (140) comprises a second ornamental body defining a second plane and a second latching part. The first ornamental part (120) and the second ornamental part (140) are joined at a hinge joint (130) such that the first ornamental part (120) and the second ornamental part (140) are relatively rotatable about a hinge axis (138) to move between a first configuration and a second configuration. The hinge axis (138) is defined by the hinge joint (130). The first latching part and the second latching part are to cooperate to form a latching device in a latching configuration when in the first configuration and a latching device in a releasing configuration when in the second configuration.

Abstract

A decorative item (100) comprises a hard pure-gold shell (110) and a surface-textured soft pure-gold surface layer (120) covering said shell (110). The hardness of the shell (110) is greater than the hardness of the surface layer (120). The decorative item (100) is a fully pure-gold item having the characteristics of a traditionally refined and beautiful pure-gold surface as well as the high hardness and rigidity characteristics of non-pure gold. The present invention uses an electroforming process to create a hard pure-gold shell (110) in order to provide the required support to a soft pure-gold surface layer (120). Because it is relatively simple to achieve a varied surface texture on the soft pure gold by means of surface processing, the decorative item (100) has the advantages of being refined, beautiful and intricately textured, befitting an art appreciation piece or a collectible.
