A modified version of the Round Brilliant cut, the Oval cut is an even, perfectly symmetrical design. Traditionally popular among women with small hands or short fingers, its elongated shape gives a flattering illusion of length to the hand and finger.
For characteristics similar to the Round which is more unique in style, the Oval cut diamond is an excellent choice. Similarly configured to the Round cut, the standard number of facets for an Oval is 56, with a varying number of pavilion (lower) facets of 4, 6, or 8.
Typically, Oval cut diamonds reflect light brilliantly and are usually at their best when they are of a high colour grade. The clarity and colour is much more important in the Oval cut than the Round as generally, inclusions can be much easier to spot and more difficult to hide in setting.
Oval cut diamonds are usually most pleasing at a 1.50 ratio (one and a half times as long as they are wide) (or approximate range of 1.35 to 1.65). This makes the outline elongated enough to be different from a round, but not so long that it could be confused with a Marquise.
In an Oval diamond’s with a ratio greater than 1.50, the 'bow-tie effect' can occur when a dark, bow-tie shaped area occurs, usually as the result of improperly cut angles. The Oval cut diamond should also have a symmetrical elliptical shape when viewed from the top of the diamond.
Vashi.ie recommends an Oval cut diamond with a minimum colour of G, clarity of VS2 and very good cut.
If you are looking for a good quality Oval cut diamond for a more modest budget, look for a stone with a minimum colour of H, clarity of SI1, and very good cut.
