In order to make it into durable jewelry you can wear everyday, it is mixed with other metals to add strength. The most popular alloy of gold is 10k gold, which is 58.5% pure gold and 41.5% other metals like silver and copper. Adding other metals to gold also allows us to make beautiful gold variations like white and rose gold.<br><br>Gold Jewelry Care<br>To clean your gold jewelry, soak it in a bowl of mild liquid detergent and lukewarm water. Then rinse with water and dry with a soft cloth. Be careful not to bend any prongs while cleaning, as this could loosen stones from their settings. We recommend storing your gold jewelry individually wrapped in soft cloth to protect it from being scratched.
