Brazed Joint for Attachment of Gemstones to Each Other and/or a Metallic Mount

Abstract

The specification relates to a gemstone setting. The gemstone setting includes a gemstone, a mounting surface and a braze joint. The braze joint is formed from a reactive metallic alloy with the reactive metallic alloy adhering the gemstone to the mounting surface. The braze joint is substantially concealed from a direct line of sight from a top portion of the gemstone by preventing excessive alloy from getting outside a desired braze area.

1 . A gemstone setting comprising:
 a gemstone;   at least one mounting surface; and   at least one braze joint, the at least one braze joint being formed from a reactive metallic alloy, the braze joint adhering the gemstone to the mounting surface, the braze joint being substantially concealed from a direct line of sight from a top portion of the gemstone by preventing excessive alloy from getting outside a desired braze area.   
     
     
         2 . The gemstone setting of  claim 1  wherein the mounting surface is a surface of a hollow mounting rod. 
     
     
         3 . The gemstone setting of  claim 2  wherein excess alloy is prevented from extending beyond the desired braze area by delivering the reactive metallic alloy to the desired braze area through the hollow mounting rod. 
     
     
         4 . The gemstone setting of  claim 2  wherein excess alloy is prevented from extending beyond the desired braze area by inserting the reactive metallic alloy inside the hollow mounting rod restricting the hollow mounting rod and the reactive metallic alloy in a controlled manner, and thermal brazing a delivered amount of the reactive metallic alloy. 
     
     
         5 . The gemstone setting of  claim 2  wherein the brazed hollow mounting rod is adhered to the gemstone setting. 
     
     
         6 . The gemstone setting of  claim 1  wherein the mounting surface is a surface of a solid rod having a void on an end. 
     
     
         7 . The gemstone setting of  claim 6  wherein excess alloy is prevented from extending beyond the desired braze area by positioning the reactive metallic alloy into the void and in contact with the desired braze area. 
     
     
         8 . The gemstone setting of  claim 1  wherein the mounting surface is a surface of a second gemstone. 
     
     
         9 . The gemstone setting of  claim 8  wherein excess alloy is prevented from extending beyond the desired braze area by positioning a foil containing the reactive metallic alloy on the desired braze area. 
     
     
         10 . The gemstone setting of  claim 8  wherein the gemstone is retained via pressure against a surface of the gemstone and the desired braze area with the reactive metallic alloy being placed between the desired braze area and the mounting surface. 
     
     
         11 . The gemstone setting of  claim 1  wherein the mounting surface is a surface of the gemstone setting. 
     
     
         12 . The gemstone setting of  claim 11  wherein excess alloy is prevented from extending beyond the desired braze area by positioning a foil containing the reactive metallic alloy on the desired braze area. 
     
     
         13 . The gemstone setting of  claim 11  wherein excess alloy is prevented from extending beyond the desired braze area by positioning a rod containing the reactive metallic alloy on the desired braze area. 
     
     
         14 . The gemstone setting of  claim 11  wherein excess alloy is prevented from extending beyond the desired braze area by surrounding the desired braze area with a stopping material. 
     
     
         15 . The gemstone setting of  claim 1  wherein the braze joint is substantially concealed from a direct line of sight from a top portion of the gemstone by positioning the braze joint on or near a girdle of the gemstone. 
     
     
         16 . The gemstone setting of  claim 1  wherein the braze joint is substantially concealed from a direct line of sight from a top portion of the gemstone by inherent internal reflection and surface refraction of the gemstone.
