There may never have been a more versatile earring! 5mm faceted peridot, prong set studs are highlighted by a moss textured, fine silver irregular oval. The oval can be worn in the front of your ear or the back. Plus, you can wear the peridot studs by themselves in addition to using your own studs in the oval jackets. Oval measures about a little over an 1 1/4 in length and about 1 inch from outer edge to outer edge.
