The 15" length is great for small children as well, but it can also be worn as a choker on an average size adult. The 16" length will fall just above the collarbone on an average sized adult woman, while the 18" chain will fall just below it. A longer 20" will likely fall just above the bust, and a 24" chain will fall on the bust. Chains longer than 24" will likely reach the abdomen. For best results, we do strongly recommend using a tape measure to check neck size before placing your order.About GoldPure gold (24 karat) is a very soft metal. In order to make it into durable, beautiful 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. 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 CareTo lightly 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. 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.Chain type: RoloClasp type: Lobster claw Perfect gift for Mother's day, Valentine's day, Birthday, Christmas, Anniversary as well any other occasion!
