DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an example of a jewel support structure of the present invention will be described with reference to the drawings. FIG. 1 is a front view showing an example of the jewel support structure of the present invention, FIG. 2 is a side view of the jewel support structure shown in FIG. 1, FIG. 3 is a plan view of the jewel support structure shown in FIG. 5, bottom view of the jewel support structure shown in FIG. 1, FIG.
Is a flow chart showing an example of a method for manufacturing a jewel support structure of the present invention, and FIG. 6 is a view for explaining a method for manufacturing an annular body.

As shown in FIG. 1, the jewel support structure 1 of the present invention comprises a jewel 2 and a support 3 for the jewel 2. Jewel 2
The type is not particularly limited, and examples thereof include diamond, emerald, amethyst, and garnet. Above all, diamond is preferably used because it conforms well to the purpose of the present invention in which a groove is formed in a pavilion using a solid-state laser and the gem is supported using the groove.

The jewel 2 forms a crown 4 which forms a main part of the part to be viewed, a pavilion 5 which forms a part opposite to the crown 4, and a boundary between the crown 4 and the pavilion 5. And a girdle portion 6 for performing the operation.
Here, for example, as shown in FIG.
It is formed of a table portion forming a planar upper surface portion, and a slope portion formed obliquely downward from a peripheral portion of the table portion.

The girdle portion 6 may be linearly formed by intersecting the slope portion of the crown portion 4 and the slope portion of the pavilion portion 5, or may be parallel to the vertical direction (the axial direction of the jewel 2). In any case, it is a portion having a large cross-sectional area that forms a boundary portion between the crown portion 4 and the pavilion portion 5. Pavilion 5
Is formed on the side (inside) where the ring of the ring is located in the case of a ring, and is formed on the side (back side) that can contact the wearer's clothes in the case of the pendant. In this specification, the side where the crown portion 4 is located is referred to as “upper”, and the side where the pavilion portion 5 is located is referred to as “downward”.

The support 3 of the jewel 2 has an annular body 8 fitted and fixed in a support mounting hole 7 formed in the pavilion 5 of the jewel 2, and a frame fixed to the annular body 8. And body 9. The support mounting hole 7 is usually formed along the girdle 6 and parallel to the girdle 6 on the peripheral surface of the pavilion 5 adjacent to or slightly below the girdle 6. At the same time. However, the support mounting hole 7 may be formed in a shape other than a groove shape that can be fitted to the support.

The annular body 8 is formed around the periphery of the pavilion section 5 by fitting a linear wire having a thickness corresponding to the width of the support mounting hole 7 into the support mounting hole 7. After being wound annularly on the surface, the pavilion portion 5 is cut at a location substantially coincident with the length dimension of the peripheral surface, joined at both ends to form an annular shape, and then subjected to deformation processing. . As a material of the annular body 8, a noble metal such as platinum (Pt), gold, or silver is usually used.

The annular body 8 is mounted on the peripheral surface of the pavilion 5 so as to be invisible from the side of the crown 4 of the jewel 2 (a direction from above to below). As a result, when the jewel 2 is viewed from the side of the crown 4, no obstruction other than the jewel is visually recognized around the jewel 2, and the viewer's attention is concentrated only on the jewel itself. It is possible to maximize the beauty of the jewelry.

The frame 9 is fixed to the annular body 8 and is formed in a shape that wraps around the pavilion 5 of the jewel 2. The lower end of the frame 9 is further joined with a connecting member 10 for connecting to a ring portion (not shown) of the ring. The frame 9 is provided with a pavilion 5 as shown in FIGS.
May be arranged along the pavilion section 5 while maintaining an appropriate distance from the pavilion section 5 or the pavilion section 5 of the jewel 2.
May be attached along the surface of the pavilion part 5 in a state of being in contact with the peripheral surface of the pavilion. In particular, when the jewel support structure of the present invention is applied to a pendant, the frame 9 usually has a pavilion of the jewel 2 to reduce the thickness of the pendant as much as possible and to prevent the wearer from being caught on clothes. Part 5
Is attached along the surface of the pavilion part 5 in contact with the peripheral surface of the pavilion.

The frame 9, like the ring 8, may be formed so as not to be visible from the crown 4 side of the jewel 2. Thereby, for example, when the jewel support structure 1 of the present invention is applied to a pendant, when the gem 2 is worn, obstructions other than the jewel cannot be seen from the viewer at the periphery of the jewel 2, and the jewel 2 can be seen. Can be further enhanced. As an example of a frame other than the frame 9 shown in FIG. 1, for example, the one shown in FIG. In FIG. 7, the frame body 19 is composed of a plurality of (for example, four) rectangular sections 18 and is fixed to the annular body 8. In this case, the lower end of each section 18 is fixed to the surface of the ring portion of the ring or the like by laser welding or the like.

Next, an example of the method for manufacturing a jewel support structure of the present invention will be described. As shown in FIG.
The gem 11 has a girdle portion 14 having a surface parallel to the axis of the jewel 11 between the crown portion 12 and the pavilion portion 13.
It has. To manufacture the gem support structure, first, as shown in FIG. 5B, at the upper end of the pavilion 13 adjacent to the lower edge of the girdle 14,
The groove 15 having a substantially V-shaped cross section is formed by using a YAG laser which is a kind of solid-state laser. Here, the YAG laser refers to a crystal of garnet (Yttrium Alminium Garnet)
The dope obtained by doping d by about 1% by weight was photo-excited by a Kr arc lamp or the like. Gems with high hardness (eg diamonds) using YAG laser
A groove having a substantially V-shaped cross section can also be formed on the surface of. In FIG. 5, the groove 15 is formed in an annular shape along the annular girdle portion 14.

Next, as shown in FIG. 5 (C), a linear body 16 made of platinum and having a circular cross section (for example, having a diameter of 0.3 m) is used.
m) is wound around the groove formed in the pavilion section 13 while contacting the groove section 15 having a substantially V-shaped cross section. After the cutting, the wire 16 is cut again so that the length of the annular platinum wire 16 is shortened by about 0.5 mm. After cutting, the annular platinum wire 16 is joined at both ends using a brazing material (joining means) to produce an annular body 16 made of platinum. Platinum is a noble metal having excellent corrosion resistance, and is preferably used as the material of the ring in the jewel support structure of the present invention.

After producing the ring 16 made of platinum, the jewel 1
The annular body 16 corresponds to the groove 15 on the first pavilion 13.
And then, using a spatula (crushing means), in a direction substantially perpendicular to the surface of the pavilion portion 13,
Is crushed ((D) in FIG. 5). As a result, the annular body 16 is crushed and spread, so that it is once removed from the jewel 11.

The removed annular body 16 is removed by cutting a portion of about 1 to 1.2 mm including the above-mentioned joint portion, and then again.
It joins using a brazing material (joining means). After joining, except for the crushed part (left part in the figure) as shown in (a) in FIG. 6, the cross section changes from a circular state to the pavilion part 13 as shown in (b). The cross-sectional shape of the groove 15 (substantially V
It is formed in a character shape. The surface of the annular body 16 is scraped off so that the cross section conforming to ()) becomes a substantially triangular shape, and the annular body 16 whose surface is processed is manufactured.

As shown in FIG. 5E, the annular body 16 thus obtained is again subjected to the groove 1 of the pavilion 13.
5 is fitted. Next, the annular body 16 has a shape obtained by cutting the surface of the girdle portion 14 and the surface of the pavilion portion 13 by extending the surface (that is, the cutting surface from both the upper side and the lower side). A file is used by using a file so as to have a shape substantially coincident with the shape formed by crossing (however, if it has a surface substantially parallel to these two surfaces, it may be slightly protruded). The surface is processed ((F) in FIG. 5). Accordingly, when the jewel 11 is viewed from the side of the crown portion 12, the annular body 16 is hidden behind the crown portion 12 and the girdle portion 14 and cannot be viewed by a viewer.

Finally, the inner portion near the upper end of the frame 17 and the annular body 16 (usually a portion formed parallel to the surface of the pavilion portion 13) are joined by a brazing material (joining means). The jewel support structure is completed. After joining, if necessary, the annular body 16 is sanded to form the crown portion 1.
Finishing is performed so that the annular body 16 is completely invisible when viewed from the side 2. When the frame 17 is further joined to a ring portion (not shown) of the ring or the like, a jewelry (ring, pendant, etc.) is completed.
