These are sterling silver Navajo pearl earrings with turquoise and spiny oyster. Navajo pearls are handmade sterling silver beads that have been oxidized then partially polished. This design creates a lovely loop which makes a more comfortable hoop alternative. They come on a sterling silver earring back and measure 2.25" long including the wire and 1.25" wide. The stones will be the same color but may not be the exact pieces in the photograph.
