This is a stunning pair of 14K White Gold Amethyst and Diamond Earrings. These amethyst earrings are faceted with a tear drop design and hang approx. 1". The back of the post are stamped 585 and after a little research this is what it means;
The number 585 is stamped on European gold jewelry to indicate that the jewelry contains 58.5 percent gold. This is comparable to the U.S. 14K marking that indicates that a piece contains 14 parts gold and 10 parts of one or more different metals, which means that it is 58.3 percent gold.
