The invention is intended for use in the jewelry industry. Body jewelry stone is made of natural or synthetic gemstone, suitable only for technical or industrial purposes. Stone layer includes a structured material deposited on at least one of its front surface. It provides the ability to use for jewelry stones, previously used for industrial or commercial purposes.
DESCRIPTION OF THE INVENTION
The invention relates to the stones for jewelry.
Stones for jewelry, especially precious stones, before being secured in a metal frame jewelry, granite or polished to reflect the incident light it, causing the stone shine. However, this assumes a minimum value and a gem of purity. For example, about two-thirds of mined diamonds are not suitable for the manufacture of stones for jewelry cut through, as a result of which they can only be used for industrial or technical purposes because of too small size, color or inclusions.
Diamond layers produced artificially by chemical vapor deposition (UCF), or too expensive, or too thin, to make of them faceted stones for jewelry, such as diamonds.
SUMMARY OF THE INVENTION
The task to be solved by the invention is to enable use in jewelry natural or artificial gemstones, particularly diamonds, which are only for technical or industrial purposes are currently in use.
According to the invention this task is achieved in the stone for jewelry comprising a stone body made from natural or artificial precious stone, only suitable for technical or industrial purposes, and a structured material layer coated on at least one of its front surface.
Preferably, the stone body is made by deposition of diamond from the gas phase on a substrate such as silicon. In another preferred embodiment, the stone body consists of a polycrystalline diamond aggregate front surface preferably is smooth, concave and / or convex.
Structured fabric layer can be made great, for example of a noble metal or titanium nitride.
As the adhesive connecting means between the front surface and a structured layer of material may be included a layer of metal such as titanium or chromium.
Structured fabric layer on the transparent protective layer, for example, obtained by the method of vapor deposition may be applied, and consists of corundum or diamond.
stone body may form a clock face, in particular on the ring hours, wristwatches or hours as jewelry.
The layer of material, structured in accordance with the invention, a method of lithography is applied to stone jewelry and not only gives it an attractive look. this stone body jewelry can be, for example, natural stone, such as a single rough diamond, plate, cut off from the natural stone with the help of laser technology, a single diamond layer applied method UCF preferably on a silicon substrate or a polycrystalline diamond aggregate (RCA ). Structuring the layer of material deposited on at least one flat, concave and / or convex and preferably a smooth surface can be optional adapted for jewelery stone made in accordance with the invention, so that by structuring the obtained e.g. , portrait, star image, decoration, etc. On the layer of material may be applied, preferably by FMG technology, another transparent protective layer to protect the layer from damage structured.
Particular advantages in the manufacture of jewelery stones according to the invention provides a synthesis method of diamond FMG. Through this diamond synthesis can be produced surfaces that do not differ in nature and can not be obtained in other ways. While as rarity are natural diamonds with the front surface of 100 mm 2, using the synthesis method FMG are industrially manufactured jewelry stones from the front surface, for example, 300 mm 2, and many more that are also allowed to perform patterning of the material layer, for example, for the manufacture of patterned diamond suspension. Natural diamonds are found in the form of individual unique nuggets, and obtainable by the process of FMG diamond layers can be reproduced with the appropriate choice of synthesis parameters. Thanks to this on the basis of diamond synthesis method UCF possible to produce jewelry sets. The advantage of the method of synthesis of diamonds UCF is the possibility by setting synthesis parameters intentionally varied color scheme of diamonds forming the background image or pattern. Thus, the structural solutions in different, contrasting colors may be produced in accordance with the desired qualities of stone, such as black, brown, gray, etc.

DETAILED DESCRIPTION OF THE INVENTION
The image or pattern that is to be applied on a front surface of one stone for jewelery, subjected to digital processing using a scanner and recorded in the computer's memory. The image processing program erase the gray fields of the recorded images in the memory for a black and white image, which is produced by the photo-mask.
The front surface of one stone for jewelry may be formed, for example, deposited on the silicon substrate 2 diamond layer 3 which is either on the substrate 2, either due to high content SP2 is a dark layer. 1 on the front surface of the adhesive coated connecting means 4, such as titanium or chromium layer to provide communication between the dense layer of precipitated material such as a layer 5 of gold and diamond. Structure 6 layer 5 of gold, that is, the image pattern is created in a known manner by initially applying to the layer 5 of gold photo-lacquer and then propekaniya lacquer and varnish coating on the photo-mask, so that the nail polish will light through a mask. After removing the non-illuminated areas of the photo-lacquer layer structuring produce 5 gold by plasma etching in an argon plasma. In a structured gold layer 5 is applied a transparent protective layer 7.
The invention is not limited to the described embodiment and encompasses modifications apparent to those skilled in the art. Thus, any natural or synthetic gemstone, suitable for industrial and technical use, can be used as a carrier material for the structured layer in the presence of sufficient contrast between the stone and the structure. On the front surface of several layers of different materials together and / or one upon the other can be placed at the same hologram can be obtained by appropriately structuring, especially when applied layers. Then the stones for jewelry according to the invention can serve as a decoration of industrial and / or artistic products such as watches, vases or the like, or even as dials for hours, preferably a wristwatch.
