This is a jewelry ring featuring a rounded wire (Koumaru line) and tanzanite set in an 18k gold bezel, with engraved details. I love this ring because of its beautiful sparkle, but I'm selling it because I haven't been wearing it much lately. The size is approximately size 9 (I don't have a tool to measure it accurately). It would look great on women or men with slender hands! - Material: Silver - Stone Color: Blue-violet - Design: Relief processing - Stone Shape: Pear shape Thank you for looking.
