White Sapphire 20 Carat TW Earrings w SpecialBacks So Earrings Stay Upright. These are for my personal collection. I traded them with a friend for a pair of diamond earrings that she received. Please note the photo that I tested the Metal. If the metal shown is not silver or gold, it will attract a magnet. These don’t so they are eitherwhite gold or silver. I don’t know. Please see the photo. They’re simply stunning and will stand upright on your ears because of the special backing.
