14/20 pink rose gold filled 1mm rolo chain necklace. This necklace has a spring ring closure. ABOUT OUR GOLD FILL JEWELRY: Our gold filled jewelry is made in the USA and consists of 14k gold tubing, which is then filled with brass. This gives the item the look and feel of solid gold jewelry, at a much more affordable price. Our gold filled jewelry has about 100 times more gold than gold-plated jewelry, so the gold surface will not flake, peel, or wear off. 14k 1/20 gold fill means that the gold tubing consists of 14 karat gold, and the karat gold tubing makes up 5 percent (1/20) of the total metal weight. Our gold-fill jewelry has 100 times more gold than gold-plated jewelry, and will not flake, peel, or wear off. It has the beauty and feel of solid karat gold at a price you will love!
