These are Tiffany's Open Heart earrings! They are made of silver. The backings have been lost, so it's just the earrings themselves. I purchased them about 8 years ago at a Tiffany's store. It's a classic design and a very popular series that is still sold today(^^) They might look a little dark in the photos, but they are actually shiny silver. I will include the Tiffany's pouch and paper bag shown in the photos. The box is slightly discolored.
