About Gold: Pure gold (24 karat) is a very soft metal. In order to make it into durable, beautiful jewelry you can wear every day, it is mixed with other metals to add strength. The most popular alloy of gold is 14k gold, which is 58.5% pure gold and 41.5% other metals like silver and copper. 10k gold is 41.6% pure gold and 18k gold is 75% pure gold. Adding other metals to gold also allows us to make beautiful gold variations like white and rose gold. Gold Jewelry Care: 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. Gold is a soft metal, so we recommend storing your gold jewelry individually wrapped in soft cloth to protect it from being scratched by other jewelry or objects.
