Please note that the post measures 8mm, which is shorter than a standard post.<br><br>Choosing Earring Size<br>Unsure what size earrings to buy? 5mm is the perfect size that will look great on most people. If you are purchasing earrings for secondary ear piercings, we would recommend the 3mm size. Sizes larger than 5mm are great statement earrings, and sizes smaller than 3mm are perfect for a second hole piercing, fora cartilage piercing, or when you want just a hint of shine.<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 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. 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.
