If you're looking to invest in a lifetime piece, this is for you! These hoops are timeless staples you will never take out. Gold-filled jewelry is the closest thing to solid gold. Gold-filled pieces contain more than 100x more gold than gold-plated jewelry. For an item to be classified as gold-filled, 5% of the total weight of the item must be made up of gold. The layer of gold is much thicker and stronger, therefore more resistant to tarnishing. Also available in Silver.
