How to do Electroforming to make gold jewelry

Few gold plating solutions are 100% Faradic efficiency. Pure cyanide golds run at about 90-95% while acid hard golds are 75-80%. A home brew could be even less. This is not the solution failing to comply with Faraday but other reactions account for the missing current. There is a further issue in calculating thickness from the weight.

Process mineralogy of gold: Gold from telluride-bearing ores

Petrographic and microanalytical studies of gold in gold-silver telluride deposits show that it occurs as “visible gold” extracted by cyanidation, and as visible gold and “invisible gold” that are unamenable to cyanidation. Two gold-bearing tellurides, calaverite and buckhornite, are considerably less amenable to cyanidation in comparison to Au-Ag tellurides. Secondary ion mass
