What is stress fracturing? Stress fracturing is a problem associated with white and lower karat gold. Gold of 10 kt or less are susceptible. White gold often has this problem. Stress fracturing is caused by chemicals that dissolve the alloy out of the gold which, of course, weakens it. This can cause an item to suddenly just break for no apparent reason. This is most often seen as a prong tip on a white gold setting that is suddenly missing. Chlorine is one chemical that can cause this problem. Never soak your jewelry in strong cleaners.
Why does my fine jewelry turn my finger black? This is most often not a problem with the quality of the metal. Whenever a metal is ground into a fine enough powder, that powder is black. If the hand cream or makeup that you are using contains any abrasive materials, this will rub on the piece of jewelry and create a black smudge. Many of the materials used to color makeup are mild abrasives.
