One of the easiest ways to customize an engagement ring is by altering the shank – the band of the ring. While there are many different designs, one of the most popular is the split-shank. The band of the ring divides in two on either side of the center stone, leaving a small gap. Where the shank splits can create vastly different designs; a larger division gives a ring an antique feel, especially if its set with pavé diamonds. Meanwhile, a smaller split is a subtle way to make the center stone look larger.
