Abstract: Method for gluing decorative stones (1) with a tapered off backside, in particular of faceted glass, onto leather (2), wherein in the fastening region of each stone (1) a recess (5) is punched out of the leather (2), which recess is smaller than the greatest diameter of the stone (1). The end of the recess (5) facing the stone (1) is expanded by stamping corresponding to the contour of the stone (1). The stone (1) is subsequently glued in the expansion (6) to the base layer (4) of the leather (2).

Abstract: A string of beads with deformable connecting pieces which extend between each pair of adjacent beads and which are secured to the beads, wherein the connecting pieces are plastics threads or flexible wires.

Abstract: A method of coloring cut gemstones introduces metals or metal oxides into a surface layer by means of heat treatment. During the heat treatment the gemstones are laid on a solid plate and the metals or metal oxides form a substantial constituent of the plate. The surface of the gemstone is protected from direct content with the metals and metal oxides in the plate by a layer containing non-coloring oxides.

Abstract: A lighting system has at least one decorative transparent member which has at least one bore with at least one light source for illuminating the at least one decorative transparent member. The lightning system further has a mechanical holder which extends into the bore for holding or hanging the at least one decorative transparent member. Each light source is arranged in the bore of the respective decorative transparent member, and the current supply to each light source takes place through the respective holder.

Abstract: An electric lighting device is in the form of a candle, in particular a Christmas tree candle. It has at least one light source and a mechanical holding device for detachable attachment to a support, in particular a tree branch. The electric lighting device includes a candle stem and a lighting section in the style of, in particular, a flame. The candle stem (4) and the lighting section (5) consist of a transparent material which is preferably polished in a facetted manner.

Abstract: Process for the measurement of the surface of a polished precious stone, wherein firstly the position of at least some of the flat facet surfaces of the stone is measured in space, in particular by rotating the stone in front of a light source and examination of the shadow cast by the stone, and the facet surface is then observed under direct light.

Abstract: An apparatus is used to apply glass elements with a non-mirrored rear side to, in particular, a textile substrate. The predominant proportion of the glass elements is in the form of balls (1). At least 5% of the glass elements comprise flat boundary surfaces, and the glass elements are applied to the front side (3) of a foil (5) to form a surface. At least a portion of the glass elements comprises balls (1) provided with facets (2).

Abstract: A decorative stone made of glass is provided with a facetted front and a mirrored rear converging from the periphery of the stone to a point provided with an adhesive (10), wherein the angle between opposite surfaces of the rear of the stone (1) is more than 150°.

Abstract: A setting, in particular for decorative stones made of cut glass, is made of stamped sheet metal. It receives the decorative stone in the manner of a cup, the setting surrounding the stone in the area of its greatest diameter in the manner of a channel. At least the upper edge (3) of the setting (2) clasping the decorative stone (1) has a reduced metal sheet thickness.

Abstract: A marking element for carriageways, comprising a cylindrical housing (18) in which there is arranged at least one light source whose light issues through a flat boundary surface, flush with the carriageway, of a transparent part (2′) of the cover (2) of the housing, wherein the light coming from the light source extends in the interior of the cover at an angle with respect to the boundary surface, which is close to the limit angle for total reflection, and wherein the light source is mechanically connected to the cover (2) which can be connected to the housing (1) in different angular positions.

Abstract: A gemstone has a faceted crown which is inclined with respect to the main axis and which is defined on the one end by a preferably flat table and on the other hand by a peripheral edge of the gemstone. A faceted pavilion is inclined with respect to the main axis, adjoins the peripheral edge, and converges to a tip. The facets (3) of the crown (2) are all inclined at the same crown angle (&bgr;) with respect to the main axis (1), while the facets (7, 7′) of the pavilion (6) are inclined at two different pavilion angles (&agr;1, &agr;2) with respect to the main axis (1). The first set of facets (7) of the pavilion (6) which are inclined at a first pavilion angle (&agr;1) extend to the peripheral edge (5), and the second set of facets (7′) of the pavilion (6) which are inclined at a second pavilion angle (&agr;2) start from the tip (8) without reaching the peripheral edge (5).
