These sterling silver, blue agate earrings are simply stunning! These gemstone earrings feature natural, blue agate stones. The color is just gorgeous, a vibrant sky blue. The stones measure 5/8 in. in length and 3/8 in. in width and have lovely facets to them. See the last photo for scale. The blue agate stones are set in .925 sterling silver. I attached the gorgeous gemstones to rounded and flattened sterling silver ear wires. This unusual shape adds to the originality of these earrings. Length: 1.75 in.
