Abstract

A master alloy designed to be mixed with a predetermined weight percentage of gold to obtain a white gold alloy containing a predetermined weight percentage of germanium for gold-whitening purposes, a predetermined weight percentage of at least one plasticizing metal, adapted to impart malleability to the master alloy and a predetermined amount of a binding metal to form a solid solution. The binding metal is selected from the group of elements whose electronegativity value is substantially equal to that of germanium, for homogeneous distribution of the latter within the solid solution. A gold alloy with a Yellow Index of less than 32, comprising a predetermined weight percentage of gold mixed with the master alloy to make a white gold article.
