Abstract

The piece has a mineral support unit with a body (1) having facets (11) imitating the shape of large cut precious stone e.g. diamond, rubies, emeralds, where the body is in metal. The body has an outer wall on which minerals (3) of different colors and dimensions are fixed. The facets have cavities forming housing and fix the minerals by setting, anchoring, insetting and/or pasting. An independent claim is also included for a method for fabricating an ornament piece.

Description

The present invention relates to an ornamental piece.

  The ornamental pieces according to the invention are intended more particularly for the luxury, clothing and decoration industries.

  In jewelery or goldsmithery articles and in particular jewelery generally comprise a support element of minerals and / or precious stones cut. This element may consist of a ring forming a ring, a chain for pendant necklace or bracelet, a pin pin, earrings, ....

  Generally, this support element is made of noble or precious metal and comprises means such as claws ensuring the connection by crimping with the stone or stones.

  However, the aesthetic aspect as well as the quality of the jewel depend very strongly on the dimensions and the mode of size of the stone.

  However, stones represent the largest part of the cost of this type of item and their price traditionally varies exponentially with their size.

  There are, however, sectors such as clothing and decoration, and especially trimmings where the average price of stones is a major obstacle for applications that are aesthetically interesting.

  The present invention aims to offer on the market an article producing substantially the same aesthetic effect as a jewel with a large stone but without using a single gem or large caliber.

  This object is achieved according to the invention by means of a part characterized in that said element consists of a faceted body reproducing the shape of a large gemstone cut and on the outer wall of which are fixed small minerals dimensions.

  According to an advantageous characteristic, said facets have cavities for housing and fixing said minerals.

  According to another characteristic, said body is made of metal. Preferably, this metal is a noble or precious metal.

  According to yet another characteristic, the two-by-two adjacent facets carry minerals of different colors and / or dimensions.

  According to yet another advantageous characteristic, said minerals are crimped on the body.

  According to a particular variant, said minerals consist of cut stones and, if necessary, precious stones.

  Another object of the invention is a method of manufacturing an ornamental piece, characterized in that the molding of a faceted body reproducing the shape of a large cut stone, is made from a material curable liquid, it is made on said facets cavities for housing small minerals and then brought and fixed said minerals in said cavities.

  According to a variant of the method, said cavities are produced by molding together with molding of the body.

  According to another variant, said cavities are made by machining by means of a computer-assisted machine tool.

  According to a specific variant, the minerals are fixed in said cavities by crimping. According to another variant, said minerals are fixed by gluing.

  The parts according to the invention make it possible to obtain an aesthetic effect comparable to that produced with stones of several carats but at a much more economical cost, which allows their use in sectors such as clothing and decoration where the demand is very high. strong.

  The aesthetic effect is even more remarkable because of the multitude of minerals and possible variations of colors and sizes.

  The present invention will be better understood on reading the following description with reference to the drawings in which; FIGS. 1A and 1B show respectively a profile and a perspective view of an embodiment of the part of the invention after the initial step of the manufacturing process. FIGS. 2A and 2B show respectively side and side views. perspective of the embodiment of FIGS. 1A, 1B after the second step of the manufacturing process, FIGS. 3A and 3B show the part of the preceding figures during packing, and FIGS. 4A, 4B show respectively views of the profile and the face of FIG. a jewel provided with a piece according to the embodiment of the preceding figures.

  FIGS. 1A and 1B show a faceted body 11 made, for example, by molding from a rare, noble or precious metal such as gold, platinum or silver in the molten state, then hardens by cooling.

  The body 1 could also be made of a curable polymeric material.

  This body 1 can be made in hollow or full form, with a closed or open envelope.

  The dimensions as well as the geometry of the body 1 and those of the facets 11 are determined so as to reproduce or imitate those of the large cut stones (diamond, ruby, emerald, etc.) whose weight is generally of the order of several carats.

  The body 1 has dimensions generally between 1 and 10 cm and the arrangement of the facets and their geometry correspond to those obtained on the precious stones by a so-called modern diamond cutter size.

  In the embodiment shown, the body 1 is in the form of a cabochon with a tip 12 at its lower part and a plate 13 at its upper part.

  Here, all the faces of the body 1 from the molding are smooth and it is then planned to carry out a subsequent machining operation to make cavities 10 on the facets 11 as shown in Figures 2A and 2B.

  This operation is preferably performed by means of a machine tool possibly assisted by a computer or a robot.

  The cavities 11 form housings intended to allow the subsequent fixation of minerals 3 by crimping, anchoring, inlaying and / or gluing.

  For industrial manufacture in large series, gluing is the most appropriate method of attachment, in particular with fast-setting and strong adhesives such as glues of the cyanoacrylate family.

  The dimensions of the cavities 10 are therefore adapted to the size of the various stones chosen to fill the facets 11 of the body 1.

  According to an alternative method, it is possible to provide direct molding of said cavities 10 during the manufacture of the body 1.

  The packing is performed as shown in Figures 3A and 3B, positioning, after calibration, the minerals 3 in the various cavities 10 manually with the help of a binocular or robotically.

  These minerals are then fixed by crimping or gluing using a glue traditionally used for this type of material.

  It is advantageous to provide, for example, that on the entire body 1, facets 11 adjacent two by two, will carry minerals 3 and, for a jewel, preferably precious stones of different colors and / or sizes of to enhance the effect of shine and reflection.

  Once the body 1 filled with all its stones, it is mounted on a support member which is, in the embodiment of Figures 4A and 4B, consisting of a ring 2 ring.

  The body 1 is here set or crimped on the ring 2 by anchoring in a cradle formed at the ends of two pins 20.

  The pins 20 each result from the junction of two projecting branches 21, 22 which extend tangentially from the ring 2.

  The tip 12 comes here in wedging contact with the ring 2.

  In a variant not shown, the body 1 is directly welded to 1 support member 2.

  I o For this purpose, the body 1 will have a free connection area for connection by welding, brazing or bonding.
