Abstract

The method involves cutting a colorless rock crystal by a gem cutter in the shape of a convex lens (1). A color or white mother-of-pearl plate (2) is adjusted to the size of the rock crystal lens. The mother-of-pearl plate is adhered to the lens, under a vacuum chamber bell-jar (4), using an adhesive (3) polymerized by ultraviolet radiation. The radiation comes from an ultraviolet lamp (5) placed above the bell-jar.

Description

La présente invention concerne un procédé technique créantThe present invention relates to a technical process creating

un effet d'irisation (jeu de couleurs observé dans les pierres à travers lesquelles la lumière se décompose et donne les couleurs de l'arc en ciel. Guide des pierres précieuses. Walter Schumann).  an iridescent effect (a play of colors observed in the stones through which the light breaks down and gives the colors of the rainbow, a guide to precious stones, Walter Schumann).

ou d'adularescence( Phénomène lumineux qui se distingue par 5 un reflet d'un blanc bleuté qui semble glisser sur toute la surface d'une pierre lorsqu'on la bouge. La pierre de lune par exemple. Guide des pierres précieuses.Walter Shumann).  or adularescence (a luminous phenomenon that is distinguished by a bluish-white reflection that seems to slide over the entire surface of a stone when it is moved, such as moonstone, a guide to precious stones.Walter Shumann ).

à la surface d'un cristal de roche incolore. Il s'agit de la taille et du montage (par collage ultra violet sous vide), de deux 10 éléments naturels: le cristal de roche et la nacre de couleur ou blanche.  on the surface of a colorless rock crystal. It is the size and the assembly (by ultraviolet gluing under vacuum) of two natural elements: the rock crystal and the mother of color or white.

Le cristal de roche est taillé par un lapidaire en forme de lentille convexe (1) (de quelque forme que ce soit, ronde, ovale, carrée etc..). Cette taille permet une grande diffusion de la lumière et fait office de loupe. Fig.1 a et l b Une lamelle de nacre de couleur ou blanche (2) est ajustée 20 à la dimension de la lentille de cristal de roche. Fig.2 Cette pièce de nacre est ensuite collée à la lentille, sous cloche à vide (4) avec une colle polymérisant: aux ultra violets (3). Fig.  The rock crystal is cut by a lapidary shaped convex lens (1) (of any shape whatsoever, round, oval, square etc ..). This size allows a large diffusion of light and serves as a magnifying glass. Fig. 1a and 1b A color or white mother-of-pearl lamella (2) is adjusted to the size of the rock crystal lens. Fig.2 This piece of mother-of-pearl is then glued to the lens, under a vacuum bell (4) with a polymerizing glue: ultraviolet (3). Fig.

3 Ceux ci provenant d'une lampe (5) placée au dessus de la cloche.3 Those coming from a lamp (5) placed above the bell.

25 L'emploi d'une cloche à vide permet d'éviter toute bulle d'air entre la lentille et la lamelle, et permet d'obtenir la pression nécessaire au collage parfait. La colle u. v a la même réfraction que l'air, elle est donc neutre de toute anomalie optique. Elle est incolore et limpide.The use of a vacuum bell makes it possible to avoid any air bubble between the lens and the blade, and makes it possible to obtain the pressure necessary for perfect bonding. The glue u. v has the same refraction as air, so it is neutral of any optical anomaly. It is colorless and limpid.

30 La lentille ainsi traitée devient irisée (si la nacre est de couleur) ou adularescente comme une pierre de lune (si la nacre est blanche).The lens thus treated becomes iridescent (if the nacre is colored) or adularescente like a moonstone (if the nacre is white).
