Oval Diamonds These have always given off a vintage vibe, and that is exactly what has served to revive the style this year. A splendid choice for women that adore round and emerald diamonds, ovals appear in a wide range of length-to-width ratios, which means everyone can find what they want. Traditionally, this ratio is around 1.5, but it is possible to get something rounder or more elongated.   East-West Settings A center stone is usually set to run vertically on the finger, but that has gotten old. A new twist on the classic sets the stone horizontally, or east-to-west. Most stones can be set this way, provided they are not symmetrical in every direction. Pear Shaped Diamonds This cut is one of the most unique among the different diamond shapes. Marked by a modern, asymmetric shape, a pear cut diamond is typically long and goes well on a short finger.
