This necklace is made of solid 14k gold (not plated or filled) and stamped "14K " (585). This classic necklace looks great alone or with your favorite pendant.<br>Chain is 7.2mm thick.<br><br>Choosing Chain Length<br>On an average size man, an 18" necklace will look like a "choker." A 20" necklace will fall right above the collarbone, a 24" necklace will fall at the top of the chest, and a 30" necklace will fall in the middle of the chest. Any longer necklace will likely reach the abdomen. For best results, we do strongly recommend using a tape measure to check neck size before placing your order.<br><br>About Gold<br>Pure 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 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.<br><br>Gold Jewelry Care<br>To 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.
