As a general rule, the heavier the article of jewelry, the more gold content it has, however, this is not a dependable way to discern the authenticity of the jewelry you own or purchase. If you want to know what you have or are purchasing, look on the inside the article for the stamped information it contains. Gold jewelry should contain a K stamp followed by a number indicating the purity of the gold… the higher the number, the purer the gold content.
