摘要
A method for positioning a diamond stone in an indented shank is described. A wetting agent put in contact with a diamond draws it upwardly into the indentation in the shank. A brazing material is added to the wetting agent to be drawn into the interface between the diamond and the shank indentation. After drying the wetting agent from the assembly, a laser beam heating the shank effects a strong, acid resistant braze of the shank and diamond. A novel brazing material in weight percent of 71% silver, 28% copper, 0.75% nickel, with 0.25 to 0.35% in the aggregate of any one or more of ruthenium, rhodium or iridium provides a strong bond with significant acid resistance.
