This ring is made with a small nugget of lime green sea glass, bezel set in fine and sterling silver. The ring band is made with rounded flattened wire and is finished in size 6. The glass is 12mm long and 6mm wide. Due to the fragility of sea glass, this ring cannot be resized and is only available in size 6. 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.
