This ring is made with an elongated piece of translucent off white sea glass set in a fine and sterling silver bezel cup. The ring band is made with comfortable flat rounded sterling wire. This piece of glass is 5mm wide and 11mm long. Due to the fragility of sea glass, this ring cannot be resized and is only available in size 8. Over time, sterling silver rings will oxidize and appear to darken in color. To keep your ring clean and remove the oxidation, wipe gently with a silver polishing cloth. Do not use liquid jewelry cleaner - this risks damage to the glass.
