Description

Detailed Description of the Invention (Industrial Application Field) The present invention applies to precious stones such as ruby, sapphire, emerald, alexandrite, or in some cases diamond, and semi-precious stones such as tourmaline, crystal, garnet, etc. The claw pieces and frame pieces for holding the stones are not visible from the surface,
To provide a method for processing jewelry made of precious and semi-precious stones, which can be securely fixed, and in which a large number of these stones are combined to form a jewelry, so-called so-called nails and frames are invisible from the surface, and the jewelry.

In addition, since diamond is the hardest substance, when using the groove forming means, it must be
It takes twice as much time, has poor workability, and is not optimal for the processing method of the present invention, but it is possible to implement.

(Prior art) Conventionally, when processing a large number of precious or semi-precious stones having shapes such as round, square, or oval shapes into jewelry, for example, vertical nails, square nails, open nails,
Alternatively, you can secure the stone from the surface by using a method called "stone retaining nail" such as split nails, or fixing a large number of stones by latching the four corners of the surface of the stone, or by embedding, frame fixing, etc. Rings, brooches, and other desired finished jewelry items have been obtained by embedding or fixing methods such as fixing the periphery with frame pieces.

With this configuration, a portion of the surface of the jewelry is always hidden by the base metal, which is the nail piece, reducing the brilliance, making it impossible to obtain 100% of the luster and surface area of the jewelry.
It is a shame that it lacks luxury and at the same time reduces its value as a jewelry.Furthermore, the nail pieces create voids between adjacent stones, which creates defects that make it impossible to obtain dense jewelry. It was hot. Furthermore, the tips of the nails may get caught on clothes, utensils, etc., causing deformation of the nails such as standing up, and the stones may fall.

Therefore, methods for processing jewelry that do not allow the claw pieces to appear from the surface include a method of brazing by applying heat, a method of simultaneous casting (one-shot casting), or a method of removing the fixed part of the stone from the fixed frame. Methods such as hitting with a chisel etc. to stop it from coming together are well known, but these methods apply heat and impact directly to the jewelry stone, resulting in color changes and cracks, and in some cases. There was a risk that the stones would peel off or split.

Therefore, in the above-mentioned method, only extremely limited stones that are as durable as possible against heat and impact can be used.

Further, prior to the present invention, a "fixing structure for decorative members" was known in Japanese Utility Model Application Publication No. 55822/1983.

However, in this configuration, a concave portion is formed in the side surface of the decorative member, that is, the girdle portion, and the retaining portion of the support fitting, that is, the claw is locked, so that the thickness of the frame portion of the bent claw is larger than that of the decorative member. There is an unsightliness that becomes visible from the surface.

Furthermore, with this technique, when the decorative members are arranged side by side, the thickness of the frame portion is more clearly revealed from the surface,
Decorative value is halved. In addition, when each decorative member is arranged in a convex arc shape, the girdle portions of adjacent decorative members expand at a radial angle, so the frame material passing through the base point of the corner and the expanded fastening portion create a considerable width between adjacent decorative members. The nail part is exposed. Since decorative members are generally extremely minute objects such as jewels, exposing the frame has the disadvantage that the aesthetic value is significantly diminished.

(Problems to be Solved by the Invention) However, the present invention provides precious and semi-precious stone jewelry in which the claws and frames are invisible from the surface, which has been developed as a result of intensive research in view of the above-mentioned conventional defects. This relates to processing methods and jewelry, in which jewelry is made by combining a large number of various kinds of precious or semi-precious stones, and the stones are partially concealed by exposing a fixing claw piece, etc. on the surface. To provide a method for processing precious and semi-precious stone jewelry and jewelry in which the claws and frames are always invisible from the surface so that the brilliance of the entire surface area can always be obtained without causing any damage.

Furthermore, the present invention does not apply heat or shock to the precious or semi-precious stones to be preserved, causing the precious or semi-precious stones to change color, peeling, cracking, or splitting, and is heat-resistant. To provide a processing method for precious and semi-precious stone jewelry, which can securely hold and fix stones that have no or have weak impact resistance, such as emerald, tourmaline, crystal, garnet, etc., and make claws and frames invisible from the surface. The purpose is to

In addition, when one or more precious or semi-precious stones are assembled to make jewelry, it is extremely easy to assemble and hold them together, making it highly workable, and can be disassembled for resizing without damaging the stones. The purpose of the present invention is to provide a method for processing precious and semi-precious stone jewelry in which the claws and frames are invisible from the surface.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention provides a method for processing precious and semi-precious stone jewelry in which the claws and frames are invisible from the surface, and a girdle in the jewelry. Precious stone and semi-precious stone blanks having a section and a pavilion section are formed with two parallel grooves parallel to the girdle section and facing each other in the pavilion section adjacent to the girdle section, while the diameter of the girdle section is forming a fixed frame accommodating one or more stones having a narrower upright wall and a bent edge that fits within the groove, and guiding a forming groove of the stones between the bent edges; A method for processing precious and semi-precious stone jewelry in which the nails and frame are invisible from the surface of the fixing frame for holding stones is fitted and fixed with an outer frame having a wall surface that closes the end of the parallel bent edge. In addition, in the pavilion part adjacent to the girdle part, two parallel grooves are formed parallel to the girdle part and facing each other, and one or more stones are guided into the parallel refraction. It features precious and semi-precious stone jewelry with claws and frames invisible from the surface assembled from a fixed frame with a rim and an outer frame with a wall that closes the ends of the parallel bent edges. The present invention is characterized by a method for processing precious and semi-precious stone jewelry in which the grooves formed in adjacent pavilion parts are circumferential grooves parallel to the girdle part.

Next, specific embodiments of the present invention will be described in detail. The processing method of the present invention can be applied to various kinds of stones, including precious stones and semi-precious stones. Furthermore, the stone 9 can be generally applied to various shapes such as round, square, oval, etc.

As an example of a precious stone, a crown part 1 and a pavilion part 3 are continuous at a girdle part 2, a table 4 is provided on the upper surface of the crown part 1, and a culet 5 is provided at the tip of the pavilion part 3.

In the present invention, two parallel grooves 6 are formed at opposite positions of the pavilion part 3 adjacent to the girdle part 2.

The grooves 6 can be formed by attaching diamond powder kneaded with oil such as glycerin to the cutting edge of a copper disk blade 7, or by using a diamond blade made by kneading the powder and base metal and baking the mixture. The rotating disk blade 7
Bring the cutting edge of the blade into contact with the groove forming position and move the mechanically gripped stone 9 to form the desired oblong groove 6.
to grind. Then, this grinding step is also carried out at a position opposite to the groove 6.

In the method of the present invention, if the pavilion portion 3 adjacent to the girdle portion 2 is a stone 9 polished into a conical shape, instead of forming the parallel grooves 6 as described above, the pavilion portion 3 is formed with the girdle portion 2. Parallel circumferential groove 6
You may form a.

Therefore, the precious or semi-precious stone with the groove 6 formed therein has a bent edge 8 whose tip is bent into a shape or a T shape.
A plurality of parallel rows of upright walls 10 are provided, and a fixed frame A with at least one side open is used, and a groove 6 formed in the stone 9 is guided between a large number of bent edges 8 on the fixed frame A. They are fitted and connected to obtain an aggregate of precious or semi-precious stones as shown in FIG.

When the grooves 6 are formed in the pavilion portion 3, the grooves 6 become difficult to recognize when the finished jewelry is viewed from the table 4 side due to the properties of the stone, the refractive index, the angle of reflection of light, etc.

Further, by fitting the bent edge 8 of the fixed frame A into the groove 6 formed in the pavilion portion 3, the fixed frame A does not appear on the surface.

When connecting a large number of precious stones or semi-precious stones forming the parallel grooves 6 by sliding and fitting them onto the parallel bending edges 8 at the ends of the plurality of rows of upright walls 10 established on the fixed frame A, it is possible to connect them by simply Sliding and fitting do not fix precious or semi-precious stones. Therefore, as shown in Fig. 3, an outer frame B with a wall surface 11 is fitted onto the outer periphery of a fixed frame A into which precious or semi-precious stones are guided and fitted, and bolts C are inserted into the bottoms of both frames A and B. The fixed frame A and the outer frame B are fixed by screwing into the screw holes D and E drilled in the wall to prevent the precious or semi-precious stones from swinging and falling off, or as shown in Fig. Alternatively, on the outer periphery of the fixed frame A into which a semi-precious stone is guided and fitted, an outer frame B is established with a wall surface 11 whose upper end engages with the stone 9 or the upright wall 10 and whose lower end engages with the bottom edge of the fixed frame A, respectively. A method in which the fixing frame A and the outer frame B are fixed using a so-called hook-in method to prevent the precious or semi-precious stones from swinging and falling off, or as in the back claw method shown in Fig. 6. A method is implemented in which the bottom edges of the overlapping fixed frames A and outer frame B are bent to either side to fix fixed frames A and outer frame B to prevent precious or semi-precious stones from swinging or falling off. be done.

In addition, the groove 6 is formed in the inclined wall part of the pavilion part 3 on the lower side excluding the girdle part 2, which is a vertical side wall of precious stones, etc., so that it can be used as a jewelry made of a collection of precious stones or semi-precious stones. The fixed frame A and the outer frame B can be prevented from appearing from the surface.

(Effects of the Invention) According to the jewelry processing method of the present invention, precious stones and semi-precious stones can be processed by using a method using a copper disc blade 7 with diamond powder kneaded with oil such as glycerin attached to the cutting edge, or by using the diamond powder kneaded with oil such as glycerin. The grooves can be formed by using a diamond blade made by kneading and hardening raw metal, but the position of the grooves to be formed is particularly limited to the pavilion part near the girdle part. year,
Since it is formed as two parallel, horizontally long grooves that are parallel to the girdle part and facing each other, or as a circumferential groove, the grooves are formed in the inclined wall of the pavilion that goes inside the outer diameter of the girdle part. becomes.

Therefore, when the bent edge of the fixed frame is guided into the groove to hold the stone, the fixed frame itself can be hidden when viewed from above the table surface, and there are no fixing claws, etc. By making the stones appear on the surface, the brilliance of the entire surface area can always be obtained without partially concealing the stones, and each stone can be retained even if the jewelry has many stones arranged in a convex arc shape. This allows the stones to be held closely together without creating any gaps due to the claw pieces or frame pieces.

Furthermore, by covering the fixed frame from the outside with an outer frame of any shape, for example a tennis racket-shaped outer frame, which has a wall surface that closes the bent edge, the stone itself can be held securely without shaking. By deforming the fixed frame by using not only a mold but also a T-shaped refractive edge, it is possible to obtain jewelry in which a large number of adjacent stones are fixed in contact with each other.

Since the processing method of the present invention does not apply impact from hitting with a nail stopper, there is no chance of damage even if the stone is not heat resistant or has weak impact resistance. Since no heat is applied to connect the stones, the stones will not change in quality.

In the jewelry processed according to the present invention, the groove is formed inside the outer diameter of the girdle part, so the groove cannot be recognized from the surface of the stone, and the fixed frame and outer frame are formed inside the outer diameter of the girdle part. Since it can be placed, the resulting jewelry has the advantage of not allowing anything other than the stone to appear from the surface. Note that the outer frame surrounding the jewelry may or may not be recognizable depending on its design.

Furthermore, by fitting the bent edge into the groove, covering the fixed frame with the outer frame from the outside, and tightening the fixed frame and the outer frame, the jewelery becomes a piece of jewelry in which the stone does not swing.
When resizing, the stone and frame can be separated, so there is no need to consider heat resistance or impact.
