These are sterling silver disc earrings. This is the small size that’s about 1/2 inch across. I love the clean modern look of this design. The stones are 4mm faceted peridot. These earrings have a polished finish and come with sterling silver ear wires (if you prefer another ear wire or have other questions, Contact Me). Other gemstones available are: blue topaz, peridot, lemon quartz, green quartz (prasiolite), garnet, citrine, and amethyst. Indicate your choice when ordering.
