Description

FIELD OF THE INVENTION

The present invention relates to a technology for manufacturing jewelry with diamonds and, more specifically, to combined jewelry with diamonds, as well as to a method for their manufacture.

BACKGROUND

Due to the rapid depletion of the resources of natural diamonds, the cost of large diamonds is becoming increasingly high. An ordinary buyer of jewelry cannot afford a piece of jewelry inlaid with a diamond weighing more than 1 ct. Although small-sized diamonds have a low price, buyers tend to like larger diamonds more.

In recent years, so that an ordinary buyer can afford to buy jewelry with a large diamond effect at a lower price, diamond jewelry technicians have developed a method for combining diamonds to simulate the effect of a large diamond using a small diamond.

For example, Chinese Patent Document No. CN 200710076738.6 describes the characteristics of modular jewelry with a diamond insert. In accordance with these characteristics, it is intended to use a base of a noble metal having a conical lower surface. For the location of diamonds, a large number of recesses are provided on the upper surface of the base. In addition, between the recesses for diamonds, located on the outer part of the base of precious metal, there are clamping tabs. Each clamping protrusion has a triangular shape and expands radially towards the outer edge. Diamonds located on the outside of the base from a noble metal, as it were, push the diamond located in the center of the base. In addition, the outer side of the base of the noble metal is flush with the diamonds located around. Numerous diamonds and a precious metal base create the visual effect of a single large diamond.

Another example, Chinese Patent Document No. CN 201210034500.8 describes a diamond with a one in six ice pattern structure. According to this description, the manufacture of such a product includes nine stages: reverse molding of metal, polishing, painting, setting a diamond, bordering, manual corrugation, polishing, cladding and quality control. The metal structure is a cylindrical shape of a small size. The upper and lower layers are tilted inward, and their angle of inclination coincides with the angle of inclination of the diamond's faces. Using the three-layer circular drilling method, small diamonds are placed on a metal base in all those places where there is no metal. In addition, on the basis of a triangular metal grip, manual corrugation is performed to increase refraction and impart, due to the entire surface of the base, the effect of a large diamond.

Although the above patents and technology have made it possible to embody the effect of a large diamond using several small diamonds, these technologies still have the following disadvantages.

First of all, in order to fix these small diamonds in a stable position and prevent them from falling out, the metal mount is mainly used to fix the central diamond surrounded by several small diamonds. However, this leads to the formation of gaps between the central diamond and the small diamonds surrounding it. In the process of wearing the product, dust and dirt get into the gaps over time, the design makes it difficult to clean the gaps, which negatively affects the appearance of jewelry with diamonds.

Secondly, none of the methods of the aforementioned manufacturing technique makes it possible to set the design size of a small diamond that is part of a combined diamond, as well as the angle of support of the round base, taking into account the cutting angle of the main diamond. It is impossible to create a single visual effect of brilliance by mutual refraction of these small diamonds, taking into account the specific size ratio of small diamonds, as well as the design and shape of the metal part of the product. Thus, in terms of form and visual effect, a certain difference arises between these elements and a real large diamond.

SUMMARY OF THE INVENTION

The present invention allows the creation of combined jewelry with diamonds. Gaps between diamonds in jewelry are not formed, thus preventing dust from entering the jewelry, which overcomes the disadvantages of matching jewelry with diamonds of the previous design.

DETAILED DESCRIPTION OF THE INVENTION

Preferred practical applications of the present invention are described in great detail and are accompanied by drawings. It should be understood that these options for practical use are intended only to illustrate the essence of the invention, but not to limit the scope of the invention. In addition, it should also be understood that after reading the description of the invention, a person skilled in the art can make changes or changes to the present invention, and these changes or changes should also fall within the scope of the invention, as defined by the attached claims.

First example

As shown in FIG. 1-3, the combined diamond jewelry of the present invention includes a precious metal base 1 of circular cross section. The lateral surface of the support base 1 is machined taking into account the lateral structure of a large-sized diamond, thereby effectively improving the imitation of the shape of a true large diamond.

In the central position of the support base 1, a main hole for inlaying is defined 7. The six intermediate holes for inlaying 61 are evenly distributed around the circumference and around the main opening for inlaying 7. In other words, the centers of the six intermediate holes for inlaying 61 are located on the same circle. In addition, the twelve small cylinders 5 are evenly distributed around the main inlet 7. Each second small cylinder 5 belongs to a group of cylinders, and therefore there are only six groups of small cylinders 5. A metal grip 8 with a specific angle of refraction is located between two adjacent intermediate inlay holes 61. Each metal grip 8 has a preferred 90 ° corrugation angle.

In this application, the process of inlaying combined jewelry with diamonds includes the following steps.

First, the six lower diamonds 2 are inserted into the gap formed between two adjacent small cylinders 5 of the six groups; then, on each small cylinder 5, a krapon tack is formed, and six small lower diamonds 2 are fixed from the bottom with krapon tack. Six small lower diamonds 2 are superimposed on the remaining region of the lower layer of the metal support base 1.

Secondly, any two small surrounding diamonds 3, located diagonally, are inserted into an inlay for inlay 61 located between two adjacent metal grippers 8. In addition, each surrounding diamond 3 is pressed against two adjacent lower diamonds 2 and fixed together with them .

Thirdly, the small main diamond 4 is inlaid in the main hole for inlaying 7. At the same time, the main diamond 4 is pressed against the two surrounding small diamonds 3 located diagonally, so that they fit snugly against each other. Since the main diamond 4, inlaid in the center of the main inlay for inlaying 7 of the supporting base 1, is in contact with only six small lower diamonds 6 located under the diamond 4, there is no space between the upper main diamond 4 and the lower diamonds 2, thereby preventing dust from entering jewelry.

Fourth, the remaining four small surrounding diamonds 3 are held in place by the corresponding metal grippers 8, and also tightly press the central main diamond 4, which prevents dust from entering the combined jewelry with diamonds.

Fifthly, six metal grippers 8 are cut so that they allow to obtain corrugation 9 at a certain angle, and are inlaid on the side surface of the support base 1 with diamonds on the support base 1, so that a refraction angle corresponding to the face of the diamond is achieved, which improves the appearance of the whole combination jewelry with diamonds.

Sixthly, the metal part of the jewelry is plated or rhodium plated, which enhances the metallic luster, thereby improving the appearance of the entire combined jewelry with diamonds.

Second example

As shown in FIG. 4-6, the combined diamond jewelry of the present invention includes a noble metal support base 1 with a heart-shaped cross section. The lateral surface of the support base 1 is machined taking into account the lateral structure of a large-sized diamond, thereby effectively improving the imitation of the shape of a true large diamond.

Twelve metal grippers 8 are distributed around the support base 1. Among these metal grippers, two metal grippers 8 located on the end portion of the heart shape are combined to form a single unit, and the remaining metal grips 8 are evenly positioned so that the angle between two adjacent grips 8 identical. An intermediate hole 61 is located between each two adjacent metal grippers 8. Small cylinders 5 are respectively located at a distance of half and a quarter of the symmetrical line of the support base 1. The height of the small cylinders 5 is identical to the height of the metal grippers 8. A groove is formed at the top of each cylinder 5, which is preferably divided into eight identical segments. The preferred corrugation angle is 90 °. Around the small cylinder 5, located in half position on the symmetrical line of the support base 1, there are three main holes for inlay 7, so that between these holes 7 an equilateral triangle is formed. In the deepened part of the heart shape of the support base 1, two symmetrical holes 6 are located symmetrically with respect to one small cylinder 5. On two sides of the main hole 7 for inlaying the upper part of the heart shape, two symmetric holes for inlay 6 are installed symmetrically with respect to the same small cylinder 5. The above four small holes for inlay 6 form an equilateral trapezoid and are located at the four corners of the trapezoid, respectively.

In this application, the process of inlaying combined jewelry with diamonds includes the following steps.

First of all, the four small lower diamonds 2 are inlaid in the spaces defined between the four small holes for inlaying 6. Between these lower diamonds 2 are fixed the two lower diamonds 2 next to the small cylinder 5, forming a krapon brace on the small cylinder 5, and attached to the cylinder 5 indicated kraponovom tack. Four small lower diamonds 2 are superimposed on the remaining region of the lower layer of the metal support base 1.

Secondly, any two small surrounding diamonds 3 are inserted into the intermediate inlay hole 61 located between two adjacent metal grippers 8. In addition, each surrounding diamond 3 is pressed against two adjacent lower diamonds 2 and fixed with them.

Thirdly, the small main diamonds 4 are encrusted into the main inlay for inlay 7. The main diamond 4 surrounding the small diamonds 3, the lower diamonds 2 and the small cylinders 5 are pressed against each other so that they are firmly fixed. Since the main diamond 4, inlaid in the center of the main hole 7 of the support base 1, is in contact with only two small lower diamonds 6 located under the diamond 4, there is no space between the upper main diamond 4 and the lower diamonds 2, thereby preventing dust from entering the jewelry .

Fourth, the remaining four small surrounding diamonds 3 are held in place by the corresponding metal grippers 8, and also tightly press the central main diamond 4, which prevents dust from entering the combined jewelry with diamonds.

Fifthly, twelve metal grips 8 are cut so as to allow a corrugation of 9 at a certain angle, and are encrusted in the side surface of the support base 1 with diamonds on the support base 1, so that a refraction angle corresponding to the face of the diamond is achieved, which improves the appearance of the whole combination jewelry with diamonds.

Sixthly, the metal part of the jewelry is plated or rhodium plated, which enhances the metallic luster, thereby improving the appearance of the entire combined jewelry with diamonds.

Alternatively, the cross section of the support base 1 may also take the form of a drop of water, an ellipse, a pear shape, a pentagon shape, and so on.

In the above embodiments of the practical application of the invention, the following preferred parameters may be used.

The size of the lower diamond of small size 2 is 0.85 mm and is within the tolerance range of ± 0.05 mm.

The size of the main diamond of small size 4 is 2.35 mm and is within the tolerance range of ± 0.05 mm.

The size of the surrounding small diamond 3 is 1.4 mm and is within a tolerance range of ± 0.05 mm.

The width of the upper part of the support base 1 is 6.5 mm, and the width of its lower part is 6.1 mm. The angle between the side surface and the front surface of the support bases 1 is 30 °, while the angle between the side surface and the bottom surface is 60 °, so the angle of inclination is identical to the angle of inclination of a true diamond. The height between the highest location of the front surface of the metal grip and the lower surface of the support base 1 is 3 mm The height between the lowest position of the upper grip surface and the lower surface of the base 1 is 2.4 mm, so that an inclination angle identical to that of the true diamond is also formed. The corrugation angle of the upper surface of the metal grip is 90 °, which allows to obtain the refraction effect of the faces of a true diamond.
