Abstract

Usage: production of jewelry from precious stones. SUMMARY OF THE INVENTION: in the manufacture of jewelry from diamond plates, diamond wastes of 0.6-1 mm thickness are used as the latter. The plates are sanded and then shaped into facets or edges. When forming a product from the resulting plates, the latter are arranged with reflective surfaces parallel to one another and fixed at a distance of 0.6-1.0 mm. 21 ill.

Description

FIELD OF THE INVENTION This invention relates to the manufacture of gemstone jewelry.

A known method of manufacturing diamonds from diamond plates obtained after sawing a thickness of not more than 1.5. mm The method includes grinding the platform plate, shaping it, grinding the top in the form of a tabular platform with a small number of faces. The bottom of the plate is cut by V-grooves located at an angle of 41 °.

It is possible to make diamonds of only traditional types from plates of the indicated size.

A known method of manufacturing diamond inserts from rough diamonds of low quality, made by simplified cutting. The method includes grinding pads, bottom faceting with three faces in flat octahedron nets with angles of inclination to the site of 35-45 ° G; top three facets in flat nets of the rhombic dodecahedron asymmetrically with the bottom face with an inclination angle of 30-40 ° to the site. ,

Closest to the invention in technical essence is a method of manufacturing dies from diamond crystals from 0.8-2.2 carats or more, which consists in grinding two parallel planes of a diamond crystal and drilling a hole with a laser beam.

Such diamond crystals, due to their size, cannot be used to make traditional diamond inserts.

The aim of the invention is to reduce the cost of products.

This is achieved by the fact that in the method of manufacturing jewelry, including grinding the planes of a diamond plate, drilling a hole with a laser beam under the pendant and forming the product, diamond plates are used, which are waste from diamond production with a thickness of 0.6-1.0 mm, which after grinding they are shaped by faceting or turning of the perimeter or faceting of its two sides4 and turning of the third side, then they form the product by spreading it

Example 1. For the manufacture of jewelry in the form of pendants, a triangular-shaped diamond plate 0.6 mm thick, weighing 0.06 carats (Fig. 1.2) is used. A hole is drilled in the upper part of the plate with a laser beam (Fig. Z). Grind and polish the opposite plane of the plate with a bias to the plane of the working surface of the cutting disc at an angle of 3 (Fig. 4,5).

Based on the rational use of a triangular-shaped diamond plate with a perimeter facet, it is given the shape of a triangle (Fig. 6) or the shape of a quadrangle (Fig. 7), an elongated quadrangle (Fig. 8), a hexagon (Fig. 9), the shape of a butterfly (Fig. 10 )

The preparation of an insert plate is formed into a jewelry product, having parallel reflecting surfaces relative to each other in multiple combinations and fixed at a distance of 0.6 mm (Figs. 16, 17) in order to enhance the disperse effect.

The dispersion effect enhancement scheme (Fig. 21) is composed by the formula

N - slnl N slnr

where I is the angle of incidence of the white light beam on the surface of the insert;

d is the angle of refraction of the light ray in the diamond;

N - 2.402 - refractive index for red rays;

N = 2,465 is the refractive index for violet rays.

A ray of white light reaching the plate At is refracted and decomposes into component colors. The decomposition of white light emerging from the plate A1 and entering the plate A2 is enhanced by refraction. An even greater increase in the decomposition of light occurs in plate A3. A ray of white light, perpendicular to the surface of the diamond plate, passes repeatedly through the plate and

leaves decomposed from red to purple. Repeated combination of diamond plates enhances the disperse effect.

Example 2. For the manufacture of jewelry in the form of pendants, a triangular-shaped diamond plate with two angles 0.8 mm thick and 0.10 carats weighed together is used (Fig. 1.2). In the upper part of the plate, a hole is drilled with a beam

laser (Fig.Z).

Grind and polish opposite plates with a bias to the plane of the working surface of the cutting disc at an angle of 5 ° (Fig. 4.5).

Taking into account the features of the selected diamond plate for the rational use of rough diamonds, it is given a heart-shaped (11) or two-arc (12), three-arc (13) shape

fish (Fig. 14) by turning its perimeter.

The resulting plate diamonds - inserts through holes are arranged in parallel with reflecting surfaces in multiple combinations at a distance from each other

the other 0.8 mm (Fig. 18,19,20).

PRI me R 3. For the manufacture of jewelry in the form of pendants using a diamond plate of a triangular shape with downward angles of a thickness of 0.9 mm, weight

0.15 carats (FIG. 1,2). Drill a hole with a laser beam (Fig.Z). Grind and polish the opposite plane of the plates with a bias to the plane of the working surface of the cutting disc at an angle

0 6 ° (Fig. 4,5).

Taking into account the features of the selected plate, it is given a teardrop shape (Fig. 15) by faceting its two sides and turning the third side.

5 The resulting jewelry inserts through the holes are arranged in a multiple combination of reflective surfaces parallel to each other at a distance of 0.9 mm.
