Combinative Diamond Jewelry and Making Method Thereof

Abstract

The invention discloses a combinative diamond jewelry, which includes: a metal supporting base on an upper surface edge of which a plurality of metal claws, each metal claw having a carving formed on its top surface; and a plurality of small sized diamonds inlaid between the upper surface of the supporting base and metal claws. Also disclosed is a method for making the same. Said major diamond, periphery diamonds and bottom diamonds are pressed with each other and secured onto the upper surface of the supporting base, and form together with the metal claws structure identical to each cutting edge angle of the diamond. No slot is formed among the diamonds of the jewelry and therefore, dust is prevented from coming into the interior of the jewelry, thus overcoming drawbacks of prior art combinative diamond jewelry. Furthermore entire shining visual effects are obtained by mutual refraction of these small diamonds and metal part according to specific size ratio of the small diamonds to metal part and shape design.

 said small sized diamond comprises: at least a major diamond and several bottom diamonds and periphery diamonds;   said several bottom diamonds are inlaid into small inlay openings in a slot of the upper surface of the supporting base and locate under the periphery diamonds;   said periphery diamonds are inlaid into intermediate inlay openings next to adjacent bottom diamonds and are pressed against and secured with the bottom diamonds;   said major is inlaid into the large opening and is pressed against an secured with the several periphery diamonds;   said major diamond, periphery diamonds and bottom diamonds are pressed with each other and secured onto the upper surface of the supporting base, and form together with the metal claws structure identical to each cutting edge angle of the diamond.   
     
     
         2 . The combinative diamond jewelry as recited in  claim 1 , wherein the major diamond, bottom diamonds and periphery diamonds are inlaid into the upper surface of the supporting base by any one or more of nail inlaying, forced inlaying or claw inlaying. 
     
     
         3 . The combinative diamond jewelry as recited in  claim 1 , wherein the cross section of the supporting base is of a circle; a large inlay opening, intermediate inlay opening and several cylinders located concentrically around the large inlay opening are disposed on the upper surface of the supporting base; and said bottom diamonds are secured among these small cylinders by nail inlaying. 
     
     
         4 . The combinative diamond jewelry as recited in  claim 1 , wherein the cross section of the supporting base is of a heart; two additional small cylinders with the height identical to that of the metal claws are disposed on the upper surface of the supporting base;
 and the bottom diamonds are mounted into the small inlay openings by combination of nail inlaying and forced inlaying.   
     
     
         5 . The combinative diamond jewelry as recited in  claim 1 , wherein the cross section of the supporting base is of an ellipse, water drop, pyriform or octagon. 
     
     
         6 . The combinative diamond jewelry as recited in  claim 1 , wherein the upper width of the supporting base is 6.5 mm, while the lower width thereof is 6.1 mm; the angle between the side surface and upper surface of the supporting bases is 30°, while the angle between the side surface and bottom surface is 60°. 
     
     
         7 . The combinative diamond jewelry as recited in  claim 1 , wherein the diameter of the bottom diamonds is in a range of 0.80 mm-0.90 mm; the diameter of the major diamond is within 2.30 mm-2.40 mm; and the diameter of the periphery diamonds is within 1.35 mm-1.45 mm. 
     
     
         8 . The combinative diamond jewelry as recited in  claim 1 , wherein the inclination angle of the upper surface of the metal claws is identical to that of the diamond cutting surface inclination angle. 
     
     
         9 . A method for making a combinative diamond jewelry as recited in  claim 1 , comprising the steps of:
 (1) sample making; (2) reverse molding; (3) finishing; (4) polishing; (5) diamond setting; (6) welding; (7) polishing; (8) plating, wherein:   the step (5) further comprises the steps of:   (1) inlaying the bottom diamonds into the small inlay openings to fill a bottom layer of a supporting base;   (2) inlaying the periphery diamonds into the intermediate inlay openings adjacent to the large inlay opening, and securing the periphery diamonds together with the bottom diamonds;   (3) inlaying the major diamond into the large inlay opening, and securing the major diamond together with the adjacent periphery diamonds;   (4) inlaying the rest periphery diamonds into the rest intermediate inlay openings respectively and securing and pressing the major diamond;   (5) each metal claw being craved with an angle of 90° such that the metal claw, side surface of the supporting base, major diamond and periphery diamonds form together each refraction face of the diamond;   (6) performing plating or rhodium plating to the supporting base and metal claws to further improve metal blare, thus improving blare and reflectivity;   plating of said step (8) further comprise the steps of:   {circle around (1)} prepare plating white solution   Take 30 ml rhodium solution using a measuring cup and add this solution into a rhodium plating container and evenly stir the solution; after addition of rhodium solution, ultra-sonic vibration for 30 seconds is required such that the final solution is uniform. Switch on ultra-sonic cleaning machine dedicated to rhodium solution. After vibration, switch off the machine.   {circle around (2)} Plating   a. Add water into the ultra-sonic cleaning groove such that water level is 1.5-2.5 cm lower than the ultra-sonic cleaning machine edge after addition of plating solution into the container;   b. Switch on ultra-sonic cleaning machine such that the temperature is 45° C., and the ultra-sonic cleaning machine begins heating.   c. Plating is conducted when the temperature meter indicates the temperature within a range of 45±3° C. During plating, voltage is from 3V to 5V and duration is 25-30 s.   {circle around (3)} Cleaning   After finishing of the plating, the product is taken out of the solution. The electrode clamps are released to get the product out and then the product is washed using clean water.   
     
     
         10 . The method for making a combinative diamond jewelry as recited in  claim 9 , wherein the small inlay openings are small cylinders; and the bottom diamonds are inlaid between small cylinders by means of nail inlaying.
