Emerald - May Birthstone. SIZE 6 This new line of rings features raw gemstones wrapped with sterling silver wire. Stone varying in size from 5mm-10mm. When purchasing this ring, it should be ordered a size smaller than what is needed, because they fit "big". On a ring mandrel (the tool used to determine the size of a ring), it will read the correct size, but that does not account for the space that's created between the two wraps around the band, and this is why the rings fit "big". Example - if you typically wear a size 6, you should order a size 5.
