The invention relates to the jewelry industry, namely to cut diamonds.

Famous jewelry stone, consisting of a pavilion, a girdle and a crown with a platform, the first mathematically calculated Tolkowsky (diamond jolkovskogo). The crown has a deck, main facets, wedges, platforms and wedges crowns. The pavilion contains the main facets and the wedges of the pavilion. The angle of the main faces of the crowns is 34.5°and the angle of the main facets of the pavilion 40,75°. The diameter of the platform is to 53.0%, crown height of 16.2%, the depth of the pavilion to 43.1%, and the height of the girdle does not exceed 2.0% of the girdle diameter (Nigeria, Uposatha. Jewelry stones. - M.: Nedra, 1983. - P.52-53).

Closest to the proposed technical solution is jewelry stone "Sahabat", consisting of the crown, girdle and pavilion. The crown has a deck, main facets in the form of quadrangles adjacent to the platform edge. The inclination of the plane of the girdle main faces of the crown of 16.5°paired quadrangles crowns 54,74°, the main facets of the pavilion 42,5°paired quadrangles pavilion 47,5°, the diameter of the pad is equal to 40.0%of the height of the crown of 18.4%, the depth of the pavilion of 48.1%, and the height of the girdle does not exceed 2.0% of the girdle diameter (patent RF №2131206, CL 6 AS 17/00, 1999).

However, the known form of the proofs of the diamond "Sahabat" has the following disadvantages: the process of making this diamond consists of two stages: grinding and polishing, the utilization of the diamond raw material in the form of octaedra does not exceed 67.5%of.

The aim of the invention is to reduce the complexity of stone processing and increase the utilization of rough diamonds.

This goal is achieved by the fact that the diamond "Timur", consisting of a pavilion, crown area and the girdles, the latter takes the form of a rectangle with truncated corners, and side faces which are polished, which allows us to produce a diamond without peeling and to increase the utilization of rough diamonds.

Figure 1 shows the proposed diamond "Timur" - top view; figure 2 is a side view; figure 3 bottom view.

Diamond consists of a crown 1, the girdle 2 and hall 3. The crown has a deck 4, 8 main faces 5 in the form of quadrangles, 8 wedges platform 6 in the form of a triangle, 16 pairs of wedges crowns triangular form 7. The girdle has 8 faces 2. The pavilion consists of 8 main facets in the shape of a quadrilateral 8, 20 wedges (4 wedges 9, 8 pairs of wedges 10 and 8 angular pair of wedges 11). The inclination to the plane of the girdle main faces of the crown 30°, wedges platform 18°paired wedges crowns 34°, faces the girdle 90°, the main facets of the pavilion 39°, wedges 9 pavilion 50°paired wedges 10 45°, angular pair of wedges 11 41°. The diameter of the platform is 64%, the height of the Corot the Ki 15%, the height of the girdle 2%, the depth of the pavilion 43%, overall height 60% of the girdle diameter.

Calculations showed that the proposed cut of a diamond is the utilization of the diamond raw material in the form of an octahedron 20% higher than when cut at Takovska and 2.5% higher than when a diamond is cut "Sahabat". Because when a diamond is cut "Timur" does not require the process of Stripping, reduced complexity and simplified the process of its processing.

FIELD: jewelry industry; optics.

SUBSTANCE: proposed method is used for coloring fianites (man-made diamonds) in green, blue and brownish-yellow colors; proposed method may be also used in optics for production of colored light filters withstanding temperatures above 1000°C. Proposed method includes preliminary application of cobalt on fianite surface to be colored and at least one metal whose oxide is liable to spinelle-forming with oxide of bivalent cobalt, iron and/or aluminum, for example. Then material is subjected to heat treatment in oxygen-containing atmosphere at temperature above 1000°C but not exceeding the fianite melting point. The procedure is continued for no less than 3 h. Coat is applied by thermal spraying of metals in vacuum. Said metals may be applied in turn and simultaneously. For obtaining bluish-green color of fianite, cobalt and aluminum are applied at atomic ratio of 1:1 to 1:2. For obtaining yellowish-green color, cobalt, aluminum and iron are applied at atomic ratio of 1:1 :0.1-0.2. For obtaining yellowish-brown color, cobalt and iron are applied at ratio of 1:1 to 1:2.

SUBSTANCE: diamond of rectangular cut has beveled facets. Each of said beveled facets adjacent to four apexes of crown has fracture extending along diagonal line parallel to belt so as to form facet configuration wherein beveled facet is divided into lower beveled facet and upper beveled facet. Upper angle of upper beveled facet crown may be made smaller than angle of lower beveled facet crown and, accordingly, even without altering of crown height, so that sign of facet is slightly smaller. Deviation angles of star facets and of second beveled facets from horizontal plane, provided that both are capable of intensive reflection, may be made small, and areas of these facets may be made large. Thus, all reflection patterns become similar in size to the extent that is preferable for visual perception. By making star facets and second beveled facets so that they have small angle of deviation from horizontal plane, extremely intensive reflection may obtained and increased areas of star facet and second beveled facets may be provided. This allows cut to be provided, which is characterized by extremely intensive reflection (the number of visually perceptible beam reflections).

EFFECT: improved rectangular diamond cut by providing optimal shape of facet configuration for increasing the number of visually perceptible reflected beams.
