Oval-cut diamonds are amongst the most requested styles today because their elongated shape creates the illusion of greater size and also makes the finger of the wearer appear longer and slimmer. The shapes of Ovals can vary within the shape itself. Their ratio can vary from a shorter, rounder shape to a thinner, longer shape. Most people prefer to work in the 1.35-1.50 ratio range. Oval-cut diamonds hide clarity very well, but will show warmth in tips. An oval is an ideal choice for a customer who likes the fire and brilliance of a round diamond but wants something a little more unique and to showcase their personality a little more.
