When Jim Toth proposed to Reese Witherspoon he went with a unique choice for the engagement ring — an ashoka cut. The rare cut isn’t a name you usually see around this site, and its rarity is exactly what makes it so special. So what is an ashoka cut?

Similar to the cushion cut, the ashoka cut is a rectangular shape with rounded corners and has 62 facets. The scarcity of extra-long rough diamonds makes the cut extremely rare and one-of-a-kind. Reese’s engagement ring, made my jeweler William Goldberg, has a 4-carat center stone that sits on a dainty pave band, similar to the ring below.
