Diamond Shape Guide

When buying a diamond for an engagement ring it’s important to be familiar with different diamond shapes available. The shape of a diamond is often mistaken for diamond cut, when in fact the two are very different. A diamond shape is the actual geometric form and structure the diamond cutter has cut and polished, whereas the cut of the diamond refers to the proportions and angles embedded in the diamond determining its brilliants. The most popular diamond shapes purchased for engagement rings consist of round and princess cut diamonds. Although both can be a wonderful choice for engagement rings, there is a host of different diamond shapes that cutters have developed – unleashing a world of diamond shape opportunities. Before you start to explore different diamond shapes, it’s important to consider individual tastes and finger sizes. For instance diamond shapes such as round brilliant and princess cut can often have a foreshortening effect, so the diamond won’t look as good on shorter fingers.

The diamond shape is best mounted in a solitaire engagement ring or shouldered with smaller diamonds. Again the diamond is ideal for enhancing shorter fingers, due to its length to width ration. Pear shaped diamonds combine an oval and a marquise shape with one pointed edge and one curved edge in the shape of a rain drop. The diamond shape will compliment smaller finger. The heart shape diamonds is the ultimate symbol of love and requires four prong settings when mounted on an engagement ring. The radian cut diamond shape can be both square and rectangular and is cut into 70 facets. Radiant cut diamonds have a vintage look with the brilliance of a round diamond shape.
