Description

  The present invention relates to a jewelry holder for cut jewels such as diamond and jewelry using the same.

Conventionally, there have been various holding devices for cut jewels such as diamond, but the most general method for holding cut jewels on a ring or the like is as shown in FIG.

That is, cut jewels are precious, and because of the original nature of jewelry that is usually worn on the jewelry, it is necessary to securely hold it in the jewelry body so that it will not fall off during use. Therefore, a plurality of large-diameter claw portions 54 formed above the ring main body 52 support the pavilion 1b of the diamond 1 from below and form a cut (not shown) on the inner surface. Meanwhile, the diamond 1 is firmly held by the ring body 52 by bending the tip of the claw portion 54 and pressing the crown 1a. On the other hand, in this state, a substantial portion of the pavilion 1 b of the diamond 1 is covered with a plurality of claw portions 54 of the ring 52.

When the cut jewel is held by the method shown in FIG. 6, the main objective is to hold the diamond 1 securely, and only incident light X from the crown 1 a side of the diamond 1 is assumed. For this reason, incident light Y (not shown here) from the pavilion 1b side is blocked by the nail portion 54 and the ring main body 52, and the diamond 1 cannot be sufficiently shined. Such a situation was the same for other conventional rings and jewelry such as other pendants.

The present invention has been made in view of such a point, and the claw portion of the annular member made of a thin wire body hardly obstructs the pavilion of the cut jewel, so that not only the incident light from the crown side but also the incident from the pavilion side. An object of the present invention is to provide a jewelry holder that can sufficiently shine a cut gemstone by making full use of light and a jewelry of a unique design using the same.

In order to solve the above-described problem, the invention described in claim 1 is an annular member having an inner diameter that is smaller than a girdle diameter of a cut jewel and has an inner diameter that is locked at least at an upper half or more in the pavilion. A jewelry holder comprising a thin wire body provided with a plurality of claw portions above, wherein the wire diameter of the thin wire body is 5% to 10% of the girdle diameter of the cut jewel, and the annular member is a polygonal body as a whole. Nail portions are formed above each corner portion, and the nail portions are bisected in the lower direction of the root to form a generally square shape as a whole, whereby the annular member is a pavilion circumferential surface of a cut jewel The claw portion is a jewel holder that holds the cut jewel by pressing the crown surface of the cut jewel.

In the present invention, it is desirable that each side of the polygonal body of the annular member is curved in the center direction.

Further, the present invention is a combined body of substantially inverted triangular members that have an overall inner diameter smaller than the girdle diameter of the cut jewel, abut against the peripheral surface of the pavilion of the cut jewel, and cover the pavilion as a whole. In the jewelry holder provided with a plurality of claw portions above a plurality of configured polygonal bodies, a fine hole is formed in the center of the combined body of the substantially inverted triangular members, and the cut gem curette It is a jewelery made of a pendant comprising a jewel holder that covers a portion from below and a cut jewel held between the jewel holder.

  According to the jewelry holder and jewelery using the same according to the present invention, not only the incident light from the crown side but also the incident light from the pavilion side can be fully utilized to shine the cut gemstone strongly. In addition, it can provide jewelry with unique designs.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following embodiment, for convenience of explanation, it is assumed that the cut jewel is a diamond and the jewelry is a pendant. 1A and 1B show a first jewelry holder 10 according to Embodiment 1 of the present invention, in which FIG. 1A is a side view thereof and FIG. 1B is a bottom view thereof. Moreover, FIG. 2 shows the pendant 20 to which the first jewelry holder 10 is attached. FIG. 2A is a side view thereof, and FIG.

  The jewelry holder 10 is mainly composed of a thin wire-like annular member 12 that abuts on the peripheral surface of the pavilion 1 b of the diamond 1. For example, the annular member 12 is manufactured by processing a precious metal ingot such as gold, platinum, or silver into a linear shape and then bending it into a desired shape, or by a lost wax casting method that is a general processing method for jewelry. Can also be manufactured.

  The inner diameter A of the annular member 12 is at least smaller than the outer diameter B of the girdle 1d of the diamond 1, and when the diamond 1 is inserted from the curette 1C side, the annular member 12 is locked to the intermediate portion of the pavilion 1b. When the inner diameter A of the annular member 12 is made larger, it is locked at a position closer to the girdle 1d, and when it is made smaller, it is locked at a position closer to the curette 1c. That is, the jewelry holder 10 is not particularly limited to the size of the diamond 1 and has a very wide application range.

  However, when the inner diameter A of the annular member 12 is reduced and locked at a position close to the girdle 1d, the claw portion 14 is necessarily shortened, and in the opposite case, the claw portion 14 is necessarily long. Therefore, in consideration of the strength of the claw part 14, it is preferable that the claw part 14 is as short as possible, and the annular member 12 can be locked at least at an upper half position or more in the pavilion 1b of the diamond 1. preferable.

  The wire diameter of the thin wire body in the annular member 12 is preferably 5% to 10% of the girdle diameter 1d of the diamond 1. For example, in the 0.5 CT diamond 1, the girdle diameter 1d is usually around 5 mm, and therefore it is preferable to form the wire diameter of the annular member 12 in a range of about 0.25 mm to 0.5 mm. It is possible to reduce the blocking of the light to be.

  The annular member 12 has a hexagonal shape as a whole, and six claw portions 14b are formed above each corner portion. Of course, the polygonal shape of the annular member 12 is not particularly limited, and any other polygonal shape or substantially circular shape instead of the hexagonal shape may be used as long as it is in contact with the pavilion 1b as a whole. The number of the claw portions 14b is not particularly limited to six, and may be determined in consideration of the strength with which the diamond 1 can be sufficiently held. For example, the larger diamond 1 forms more claw portions 14b. Of course, it is preferable.

  The nail | claw part 14 forms the substantially square shape as a whole because the base bisects downward. Thereby, even when the tip of the claw part 14 is bent, the crown 1a of the diamond 1 is pressed, and a considerable load is applied to the claw part 14, the thin wire body is strengthened by the expansion of the substantial wire diameter at the root, The diamond 1 can be sufficiently supported.

  In the state where the annular member 12 is inserted from the curette 1C side of the diamond 1 and brought into contact with the pavilion 1b, the jewelry holder 10 bends the tip of the claw portion 14 with a jewelry processing tool such as pliers, and the crown 1a Is pressed from above. That is, the diamond 1 is sandwiched between the annular member 12 and the claw portion 14 from above and below and is reliably held by the jewelry holder 10.

In addition, in the jewelry holder 10, it is preferable that each polygonal side part 16 of the annular member 12 curves inside. That is, by forming a curved shape between the claw portions 14, the annular member 12 is more elastic and can be brought into contact with the pavilion 1b of the diamond 1 in a slightly expanded state. Therefore, in a state where the claw portion 14 is bent and the crown 1a is pressed, each side portion 16 is in a state of slightly tightening the peripheral surface of the pavilion 22, and the diamond 1 can be sandwiched more firmly.

An annular ring 15 is attached to such a jewelry holder 10 and attached to the pendant 20 by a method as shown in FIG. The pendant 20 has a pedestal 21, and if necessary, a recess 24 (or a hole) is formed at the center thereof. A suspending portion 22 for attaching the jewelry holder 10 and the chain 25 is provided on the pedestal 21.

A hole 22b for inserting the ring 15 attached to the jewelry holder 10 is formed at the tip of the hanging part 22, and a hole 22a for inserting the chain 25 is formed at the base of the hanging part 22. Is formed.

In such a pendant 20, the diamond 1 attached to the jewelry holder 10 freely swings back and forth and right and left. Furthermore, the jewelry holder 10 has few parts which cover the pavilion 1b of the diamond 1, and the exposed area of the pavilion 1b becomes large. As a result, not only the crown 1a side but also the outside light from the pavilion 1b side is sufficiently incident on the diamond 1 at various angles, and the diamond 1 exhibits a strong shine.

In the pendant 20, it is the back surface of the pedestal 21 that directly contacts clothes and human skin. Therefore, in the jewelry holder 10, the acute curette 1C of the diamond 1 is exposed, but it hardly hits clothes or human skin, and does not damage clothes or human skin during use.

  In addition, there is no restriction | limiting in particular in the shape of the pendant 20 to which the jewelry holder 10 is attached. For example, in the present embodiment, the case where the pendant 20 and the chain 25 are separate is described, but the pedestal 11 and the chain 25 may be an integral pendant.

In addition, in this Embodiment, since the structure of the pendant 20 and the attachment method to the pendant 20 of the jewelry holder 30 are the same as that of Embodiment 1, description is abbreviate | omitted here.

  The jewel holder 30 is composed of a plurality of polygonal bodies that contact the peripheral surface of the pavilion 1 b of the diamond 1, for example, a combined body of substantially inverted triangular members 32. The material used for the combined body of the substantially inverted triangular members 32 and the manufacturing method thereof are the same as those in the first embodiment.

  The combined body of the substantially inverted triangular member 32 has an overall inner diameter A smaller than the outer diameter B of the girdle 1d portion of the diamond 1, and when the diamond 1 is inserted from the curette 1C side, the approximately inverted triangular member 32 is obtained. This combined body is in a state of covering the entire pavilion 1b.

  The substantially inverted triangular members 32 constitute six combined bodies. Six claw portions 32 are formed at the center of each side portion 36, and the claw portions 32 press the crown 1a from above. Therefore, the diamond 1 is sandwiched between the combined body of the substantially inverted triangular members 32 and the claw portion 34. In addition, it is the same as that of the said Example that there is no limitation in particular about the number of the coupling bodies in the substantially inverted triangular member 32, and the number of the nail | claw parts 34.

Furthermore, in the jewelry holder 30, a fine hole is formed in the central portion 35 of the combined body of the substantially inverted triangular members 32 (not shown), and covers the curette 1c portion of the diamond 1 from below. Accordingly, the diamond 1 can be securely sandwiched between the claw portion 34 and the substantially inverted triangular member 32 from above and below.

According to the jewelry holder 30, as in the above-described embodiment, the portion of the diamond 1 that covers the pavilion 1b is small, and the surface area that exposes the pavilion 1b is increased. As a result, not only the crown 1a side but also the outside light from the pavilion 1b side is sufficiently incident on the diamond 1 and exhibits a strong shine.

  The annular member 12 used in the jewelry holder 40 is completely the same as the first embodiment in its shape, material, manufacturing method and the like, and detailed description thereof is omitted here.

  A substantially elliptical ring 47 is attached to the claw portion 14 of the annular member 12 along the ridgeline direction of the pavilion 1 b of the diamond 1. Further, the ring 47 is larger than the previous embodiments, and extends to the vicinity of the curette 1C of the diamond 1 and has an outer diameter that covers the curette 1C in the longitudinal direction. . Therefore, when the jewelry holder 40 is used, even if the acute curette 1C of the diamond 1 is exposed. The curette 1C can be prevented from coming into direct contact with human skin and clothes.

  On the other hand, the cross-sectional shape of the necklace 48 used for the jewelry holder 40 is not circular, and for example, a substantially elliptical omega necklace or a flat snake necklace is used. Thus, when the necklace 48 is inserted through the ring 47, the jewelry holder 40 is fixed and does not swing in the front-rear direction. Therefore, in combination with the shape and attachment position of the annular ring 47, even if the curette 1C is exposed, it can be completely prevented from being in direct contact with human skin and clothes.

By using such a jewelry holder 40 and necklace 48 in combination, it is possible to significantly reduce the weight of the jewelry as a whole, and to provide jewelry that is superior in cost and simple in design. can do.

Of course, according to the jewel holder 40, the portion of the diamond 1 that covers the pavilion 1b is small, and the surface area that exposes the pavilion 1b is increased, as in the previous embodiment. As a result, not only the crown 1a side but also the outside light from the pavilion 1b side is sufficiently incident on the diamond 1 and exhibits a strong shine.
