Description

<Desc/Clms Page number 1> <Desc / Clms Page number 1>

La présente invention concerne un procédé de culture de perles.  The present invention relates to a pearl cultivation method.

Pour réaliser de façon industrielle des perles dites perles de culture, on connaît un procédé de culture comprenant les étapes de découper un greffon dans un manteau d'une huître donneuse et introduire le greffon avec un nucléus dans une poche gonadique d'une huître receveuse. Après une période déterminée, généralement égale à deux ans, pendant laquelle le nucléus a été recouvert de nacre par l'huître donneuse, l'huître donneuse est ouverte et la perle obtenue est extraite.  To produce pearls known as cultured pearls on an industrial scale, a culture process is known comprising the steps of cutting a graft from a coat of a donor oyster and introducing the graft with a nucleus into a gonad pocket of a recipient oyster. After a determined period, generally equal to two years, during which the nucleus has been covered with mother-of-pearl by the donor oyster, the donor oyster is opened and the pearl obtained is extracted.

Lorsque l'huître donneuse et de l'huître receveuse sont identiques, la couleur de la perle obtenue est identique à celle des huîtres.  When the donor oyster and the recipient oyster are identical, the color of the pearl obtained is identical to that of the oysters.

Par ailleurs, il est généralement admis que l'huître donneuse et l'huître receveuse doivent être du même genre et de la même espèce. Des études ont été réalisées sur l'utilisation d'une huître donneuse qui est un variant de l'huître receveuse. Le résultat de ces études a été publié en particulier dans le magazine SHINJU 40 pages 71 à 86 et il en ressort que la couleur de la perle obtenue serait nécessairement celle de l'huître donneuse.  Furthermore, it is generally accepted that the donor oyster and the recipient oyster must be of the same genus and of the same species. Studies have been carried out on the use of a donor oyster which is a variant of the recipient oyster. The results of these studies were published in particular in the magazine SHINJU 40 pages 71 to 86 and it appears that the color of the pearl obtained would necessarily be that of the donor oyster.

Cette propriété a en particulier été utilisée pour obtenir des perles blanches en utilisant comme huîtres receveuses des huîtres du genre Pinctada espèce Fucata normale qui donnent généralement des perles de couleur d'un blanc jaunâtre mais dans lesquelles on a pu cultiver des perles d'un blanc pur en utilisant un greffon prélevé dans le manteau d'une huître donneuse du genre Pinctada espèce Fucata variant albinos. Cette technique d'obtention de perles blanches est en particulier rappelée dans l'article AQUACULTURE 125 pages 59 à 65 de KATSUHIKO WADA et AKIRA KOMARU publié en 1994 par les Editions ELSEVIER Science B. V. pour l'obtention de perles blanches dites AKOYA. This property was in particular used to obtain white pearls using as oysters receiving oysters of the genus Pinctada normal Fucata species which generally give pearls of color of a yellowish white color but in which one could cultivate pearls of white pure using a graft taken from the mantle of a donor oyster of the genus Pinctada species Fucata variant albino. This technique of obtaining white pearls is in particular recalled in the article AQUACULTURE 125 pages 59 to 65 of KATSUHIKO WADA and AKIRA KOMARU published in 1994 by Editions ELSEVIER Science B. V. for obtaining white pearls called AKOYA.

On connaît par ailleurs des perles de couleur foncée cultivées dans des huîtres du genre Pinctada espèce Margaritifera particulièrement connues pour leur orient sombre allant généralement du noir à la couleur aubergine.  There are also known dark-colored pearls cultivated in oysters of the genus Pinctada species Margaritifera particularly known for their dark orient generally ranging from black to eggplant color.

Ces perles de couleur sombre connaissent un grand succès mais il est souhaitable de pouvoir cultiver des perles ayant de nouvelles couleurs pour réaliser des compositions variées de différentes couleurs ou de différentes nuances d'une même couleur.  These dark-colored pearls are very successful, but it is desirable to be able to cultivate pearls having new colors in order to produce various compositions of different colors or of different shades of the same color.

Selon l'invention, on propose un procédé de culture du type rappelé ci-dessus dans lequel l'huître donneuse et de l'huître receveuse sont de couleurs différentes l'une de l'autre.  According to the invention, a culture method of the type recalled above is proposed in which the donor oyster and the recipient oyster are of different colors from one another.

Contrairement au préjugé rappelé ci-dessus selon lequel la couleur de la perle obtenue devrait normalement être celle de l'huître donneuse, on a en effet constaté qu'il était possible par le procédé selon l'invention d'obtenir de façon régulière des perles présentant une couleur intermédiaire entre la couleur de l'huître donneuse et la couleur de l'huître receveuse. Ainsi, au moyen du procédé selon l'invention, il est possible par une sélection appropriée de l'huître donneuse et de l'huître receveuse d'obtenir des couleurs extrêmement variées permettant de réaliser des compositions originales.  Contrary to the prejudice recalled above according to which the color of the pearl obtained should normally be that of the donor oyster, it has in fact been found that it was possible by the process according to the invention to obtain pearls on a regular basis showing an intermediate color between the color of the donor oyster and the color of the recipient oyster. Thus, by means of the method according to the invention, it is possible by appropriate selection of the donor oyster and of the recipient oyster to obtain extremely varied colors making it possible to produce original compositions.

Selon un premier mode de mise en oeuvre particulier de l'invention, l'huître donneuse est une huître du genre Pinctada espèce Margaritifera variant albinos tandis que l'huître receveuse est une huître du genre Pinctada espèce Margaritifera normale. La perle obtenue présente alors un orient gris argenté très doux avec des reflets de couleur pastel type gorge de pigeon.  According to a first particular embodiment of the invention, the donor oyster is an oyster of the genus Pinctada species Margaritifera variant albino while the recipient oyster is an oyster of the genus Pinctada species Margaritifera normal. The pearl obtained then has a very soft silvery gray orient with pastel color reflections such as pigeon throat.

Selon un second mode de réalisation particulier du procédé selon l'invention, l'huître donneuse est une huître du genre Pinctada espèce Maculata normale et  According to a second particular embodiment of the method according to the invention, the donor oyster is an oyster of the genus Pinctada normal Maculata species and

<Desc/Clms Page number 3><Desc / Clms Page number 3>

l'huître receveuse est une huître du genre Pinctada espèce Margaritifera normale. La perle obtenue est une perle dorée à reflets sombres ayant un orient très chatoyant.  the recipient oyster is an oyster of the genus Pinctada normal Margaritifera species. The pearl obtained is a golden pearl with dark reflections having a very shimmering orient.

Bien entendu, l'invention n'est pas limitée au mode de mise en oeuvre décrit et on peut y apporter des modifications sans sortir du cadre de l'invention tel que défini par les revendications.  Of course, the invention is not limited to the embodiment described and modifications can be made thereto without departing from the scope of the invention as defined by the claims.

En particulier, bien que l'invention ait été décrite en relation avec une huître receveuse de couleur sombre et des huîtres donneuses de couleur claire, on peut prévoir d'inverser ces couleurs, par exemple en mettant un greffon d'une huître du genre Pinctada espèce Margaritifera dans la poche gonadique d'une huître du genre Pinctada espèce Fucata normale. On peut également utiliser comme huître donneuse ou receveuse une huître d'un genre ou d'une espèce différents de ceux énoncés, par exemple une huître du genre Pinctada espèce Maxima.  In particular, although the invention has been described in relation to a recipient oyster of dark color and donor oysters of light color, provision can be made to invert these colors, for example by placing a graft of an oyster of the genus Pinctada Margaritifera species in the gonad pocket of an oyster of the genus Pinctada normal Fucata species. One can also use as donor or recipient oyster an oyster of a genus or species different from those mentioned, for example an oyster of the genus Pinctada species Maxima.

On obtient ainsi des perles présentant différentes nuances dorées ou argentées.Pearls are thus obtained with different shades of gold or silver.
