How is the purest gold jewelry defined?
Pure gold jewelry is stamped with 24K. This refers to the amount of karats which is a measurement of the weight of gold. Jewelers in countries other than the U.S. might use a slightly different stamping system: • 100% = 999 Fine = 24K • 91.7% = 917 Fine = 22K • 75.0% = 750 Fine = 18K • 58.3% = 583 Fine = 14K • 41.
