[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION This invention relates to a decorative pearl used for necklaces, rings, beads, earrings, etc., and to a decorative pearl having a noble metal luster such as gold, silver, platinum or the like immediately below the nacre on the surface. Things.

[0002]

2. Description of the Related Art Precious metals such as gold, silver, and platinum are used for accessories such as necklaces and rings. As an inexpensive substitute, a precious metal layer is provided by plating on the surface of a base metal such as nickel silver. Things are used.

[0003]

However, since noble metals have a large specific gravity, the decorative body cannot be made too large. For example, a pearl necklace does not feel so heavy when it is hung on the neck, even if the pearl is large, but if you make such a large one with a precious metal decoration, even if the surface of other metal base material is plated Even if it is, it becomes impossible to use it as an accessory because of its heavy weight.
For this reason, precious metal necklaces and the like are formed in thin chains, and earrings and the like need to be thin and small.

[0004] This invention is a weight that is suitable for wearing, when the noble metal gloss of the inner layer can form a decorative body of a new attraction as seen through the surface, and was used as jewelry It is an object of the present invention to obtain an ornamental sphere of a certain size that is worthwhile.

[0005]

Pearl Means for Solving the Problems] forms a pearl layer those formed into a spherical shell on the surface inspires the pearl oysters as nuclei such as Dobukai, this invention is a pearl nuclei using its dependent shells 1 to cashew resin spherical urethane resin, the adhesive 2, such as an epoxy resin is coated, gold foil thereon, silver foil, was also attached a precious metal foil 3 such as platinum foil
Those which inspires the pearl oysters as nuclei for pearls by forming a pearl layer 5 on the precious metal foil layer 3 from.

[0006]

[Function] A noble metal foil is a flat one, but when a small piece wraps around a pearl 1 of a shell with an adhesive 2 applied to the surface, wrinkles or parts with a loss of metallic luster may occur on the surface. Instead, a sphere having the same metallic luster on the entire surface can be obtained.

[0007] The pearl with the noble metal foil stuck to the pearl oyster as a pearl nucleus and the pearl layer 5 is further formed thereon to provide a new texture in which the noble metal luster can be seen through from the pearly shine. A sphere having a unique decorative property can be obtained.

The sphere obtained in this way can be used as a necklace or rosary in the form of a bead. One or a plurality of spheres can be collected and used as a ring or earring.

[0009]

FIG. 1 schematically shows a cross section of an embodiment of a decorative bead according to the present invention, in which a cashew resin 2 is applied to the surface of a core 1 formed by shaving a shell such as a giant clam and a gold leaf. 3 is attached and used as the core of the pearl.
The mother-of-pearl layer 5 is formed on the upper surface.

As shown in FIG. 2 , the gold foil 3 is attached to the core 1 by placing the core 1 coated with the cashew resin 2 on a small piece 6 of gold foil cut into a small square, and then cutting it into a square. If the small pieces 6 of gold leaf placed on the core 1 are pressed against the surface of the core 1 so that the small pieces 6 of gold leaf are wrapped with fingertips, the gold foil of the portion directly attached to the surface of the core 1 remains on the surface and becomes wrinkled. Since the gold foil in the portion that has been stuck and the portion that has been laminated is torn off, the gold foil 3 can be evenly stuck to the surface of the core 1 without generating gaps or wrinkles throughout. If there is a gap where the gold foil 3 is not stuck, a small foil is stuck to that portion and rubbed, so that the gap can be filled in a state where the extra gold foil is torn off and the boundary is not visible at all.

If the core 1 having the gold foil 3 attached to the surface in this manner is embraced by a pearl oyster to form a pearl layer 5 on the surface of the gold foil 3, the gold color can be seen through from the inside of the pearl color surface. A sphere with a suitable surface is obtained.

The sphere obtained in this manner can be used as a jewelry such as a necklace, a ring, or an earring in the same manner as a pearl by forming it into a pearl or embedding it in a pedestal, and affixing silver foil or platinum foil. What was done can be used as a rosary or the like as a rosary.

[0013]

According to this invention described, according to the invention described above, since the base material is made of the same shell as the nucleus of the pearl, under the weight suitable for wear, precious metal luster Some of the true pearl color gloss With the decorative beads that can be seen through, it is possible to manufacture accessories such as necklaces and earrings, and it is possible to provide accessories that are new to the past. Further, since the base material is the same material as the conventional pearl base material, the noble metal layer formed on the surface thereof and the pearl layer formed thereon are also formed of a genuine noble metal or pearl, There is an effect that a valuable accessory can be obtained as such.
