14K Gold filled jewelry has 1/20th by weight layer of 14 karat gold permanently bonded over a core of base metal. 14K GF jewelry will not peel, flake, or ware off and can be treasured as heirloom pieces. It is tarnish-resistant like solid 14 karat gold and is safe for most people with sensitive skin who can wear solid 14 karat gold jewelry. To make sure your piece stays pretty wipe gently with a polishing cloth and please don't shower or swim with the piece on because it will deteriorate it over time. Gold is used in most sacred objects almost in every culture and for very good reasons. Gold helps purification and balance of the heart. It helps to attract wealth, happiness and all sorts of other positivity. Its also said to alleviate stress and tension. That part didn't work for me but it looks great on.
