Bow tie effect oval cut diamond

The Oval diamond one of the must popular diamond cuts nowadays is a beautiful brilliant cut diamond with a symmetrical elongated shape that gives an illusion of length on the hand, if worn on an engagement ring. It was created in the 1960s as an alternative to the round brilliant cut diamond.

The oval cut diamond is a brilliant and fiery diamond that reflects light beautifully. Like the round brilliant, it usually has 58 facets, but can vary slightly in its cut with anywhere from 4, 6 or 8 pavilion facets. There is no standard length to width ratio for oval cuts. They can be almost round, with a wider mid section and shorter length or very long and lean.

Similar to the marquise, oval cut diamonds can display a bow tie effect: a dark area shaped like a bow tie in the centre of the diamond. The bow tie effect appears in some fancy cut diamonds such as marquise, hearts and oval cut diamonds. The bow-tie effect is caused by imperfect proportions between the height, length and width of the rough diamond from which the stone is cut. Due to this imperfect structure, light leaks through the diamond's pavilion, creating a dark shadow in the center of the diamond – from both girdles to the main belly facet. The effect creates an image that is similar to a bow tie, hence its name. The effect has varying levels, and is noticeable even without a magnifying glass. When it is very dark, the bow tie significantly damages the beauty of the cut diamond.

Oval cut diamonds are the perfect option for someone who loves the fire of the round brilliant diamond, but wants to have something a little bit different. Also, the elegant shape of the oval can look beautiful in a variety of jewellery pieces, from solitaire engagement rings to anniversary rings to pendants and earrings.
