mise en valeur.de diamants taillés de faible poids, ainsi

  
 <EMI ID=2.1> 

  
 <EMI ID=3.1> 

  
Par diamants de faible poids, il faut ici entendre

  
 <EMI ID=4.1> 

  
En joaillerie, de telles pierres sont généralement groupées, n'ayant isolément que peu d'attrait visuel, de par leurs faibles dimensions.

  
On trouve néanmoins sur le marché des bijoux, par exemple des pendentifs, constitués substantiellement par une pierre de faible poids noyée dans une masse de matière synthétique transparente avec ou sans autres éléments décoratifs.

  
Dans de tels bijoux, l'élément "diamant" ne joue pratiquement plus qu'un rôle psychologique car la pierre, déjà petite au départ, disparaît pratiquement à la vue lorsqu'elle

  
 <EMI ID=5.1> 

  
ment en raison des lois élémentaires de. l'optique.

  
Le but de la présente invention est de pallier cet inconvénient. A cet effet, l'invention fournit un procédé consistant substantiellement à réaliser une première couche d'une matière transparente, cette couche étant pourvue sur une de ses faces d'une calotte substantiellement sphérique;

  
à placer sur l'autre face de ladite première couche un diamant taillé, de sorte que la table de ce dernier soit centrée sur ladite calotte; et à apporter, sur ladite première couche, une deuxième couche de matière transparente, emprisonnant ledit diamant.

  
Pour plus de clarté, l'invention est décrite en détail ci-après, avec référence aux dessins exemplatifs annexés,  <EMI ID=6.1>  <EMI ID=7.1> 

  
 <EMI ID=8.1> 

  
réaliser une première couche 1 en une matière transparente, par exemple en une résine époxy adéquate,de manière à ce que cette couche présente en saillie sur une de ses faces, une

  
 <EMI ID=9.1> 

  
On pose ensuite sur l'autre face de ladite couche 1 le diamant 3 à mettre en valeur, de manière à ce que sa table &#65533; soit centrée par rapport à ladite calotte 2.

  
Pour faciliter le positionnement correct du diamant 3, on aura avantageusement imprimé dans la face correspondante de la couche 1 une empreinte circulaire de centrage 5.

  
L'épaisseur E de la couche 1, le rayon de courbure R et la hauteur H de ladite calotte sont préférablement choisis en manière telle que le centre de courbure de ladite calotte

  
 <EMI ID=10.1> 

  
sur la couche 1.

  
Le diamètre L de la base de la calotte 2 est légèrement supérieur à la largeur maximale L' du diamant 3.

  
On forme ensuite une deuxième couche 7 de matière

  
 <EMI ID=11.1> 

  
sonner le diamant 3.

  
 <EMI ID=12.1> 

  
 <EMI ID=13.1> 

  
nier cas, on lui donnera avantageusement la forme d'une cuvette (voir figure 2) dans laquelle sera ultérieurement coulée la couche 7.

  
 <EMI ID=14.1> 

  
et 7 toute forme décorative. Par ailleurs, il est également clair que le terme "diamant", tel qu'utilisé dans le présent  <EMI ID=15.1>

REVENDICATIONS.

  
1.- Procédé pour la mise en valeur de diamants taillés de faible poids, caractérisé en ce qu'il consiste:
à réaliser une première couche d'une matière transparente, cette couche étant pourvue sur une de ses faces d'une calotte substantiellement sphérique; à placer sur l'autre face de ladite première couche un diamant taillé, de sorte que la table de ce dernier soit centrée sur ladite calotte; et à apporter, sur ladite première couche, une deuxième couche de matière transparente, emprisonnant ledit diamant.



  "Process for the enhancement of cut diamonds

  
low weight and jewelry items obtained by this process <EMI ID = 1.1>

  
enhancement. of low weight cut diamonds, as well as

  
 <EMI ID = 2.1>

  
 <EMI ID = 3.1>

  
By low weight diamonds, we must here understand

  
 <EMI ID = 4.1>

  
In jewelry, such stones are generally grouped together, having little visual appeal in isolation, due to their small dimensions.

  
However, jewelry is found on the market, for example pendants, consisting substantially of a low-weight stone embedded in a mass of transparent synthetic material with or without other decorative elements.

  
In such jewelry, the "diamond" element practically plays only a psychological role because the stone, already small at the start, practically disappears when it is seen.

  
 <EMI ID = 5.1>

  
ment because of the elementary laws of. optics.

  
The aim of the present invention is to overcome this drawback. To this end, the invention provides a method consisting substantially in producing a first layer of a transparent material, this layer being provided on one of its faces with a substantially spherical cap;

  
in placing on the other face of said first layer a cut diamond, so that the table of the latter is centered on said cap; and providing, on said first layer, a second layer of transparent material, trapping said diamond.

  
For greater clarity, the invention is described in detail below, with reference to the accompanying illustrative drawings, <EMI ID = 6.1> <EMI ID = 7.1>

  
 <EMI ID = 8.1>

  
make a first layer 1 of a transparent material, for example of a suitable epoxy resin, so that this layer has projecting on one of its faces, a

  
 <EMI ID = 9.1>

  
The diamond 3 to be highlighted is then placed on the other face of said layer 1, so that its table &#65533; is centered with respect to said cap 2.

  
To facilitate the correct positioning of the diamond 3, a circular centering impression 5 will advantageously be printed on the corresponding face of the layer 1.

  
The thickness E of the layer 1, the radius of curvature R and the height H of said cap are preferably chosen such that the center of curvature of said cap

  
 <EMI ID = 10.1>

  
on layer 1.

  
The diameter L of the base of the cap 2 is slightly greater than the maximum width L 'of the diamond 3.

  
A second layer 7 of material is then formed

  
 <EMI ID = 11.1>

  
ring the diamond 3.

  
 <EMI ID = 12.1>

  
 <EMI ID = 13.1>

  
Denying this case, it will advantageously be given the shape of a bowl (see FIG. 2) in which layer 7 will subsequently be cast.

  
 <EMI ID = 14.1>

  
and 7 any decorative form. Moreover, it is also clear that the term "diamond" as used in this <EMI ID = 15.1>

  
memory and claims does not have a narrow meaning.

  
The invention extends as of right to articles of jewelry obtained by the implementation of the above process.

  
 <EMI ID = 16.1>
