Oval Shape

Oval - This cut makes the most use of the sparkle of a round-brilliant cut, and combines this with an elongated outline which is particularly flattering on the hand. The oval cut diamond is based upon the traditional configuration of the round brilliant diamond and that's why its technical name is oval modified brilliant diamond.

The oval was invented by Lazare Kaplan in the early 1960s. A length-to-width ratio of 1.5:1 is almost universally considered a pleasing shape for oval diamonds, with any variation beyond 1.4:1 or 1.6:1 beginning to be noticeable and become an aesthetic issue.

However as with all fancies, a certain degree of individual taste is always factored into the desirability of a particular diamond's shape. Fifty-six facets are typical for oval brilliant diamonds. Over the last year or two ovals have become very popular as center diamonds for engagement rings

Generally this is cut so that the length is twice the width, but this depends, of course, on personal preference. The oval shape is very versatile, and works well in almost any setting.

Diamond Shapes

Round- This is by far the most popular diamond shape and also the most optically brilliant, because of its 360-degree symmetry. The 'ideal' round brilliant cut was calculated by gem enthusiast and mathematician Marcel Tolkowsky in 1919, to reflect and scatter the maximum amount of light. The round silhouette works with almost every mounting, from classic solitaires to the most avant-garde designs.

Round diamonds can be set in prongs, in which they are visible from all sides, or into bezel mountings. In general, well cut round diamonds should be set with the least possible amount of metal around the stone, so that it is held securely but can still have light entering it to show off its sparkle and brilliance.

The traditional choice for all occasions and preferred by many for their personal investment portfolio. The depth percentage should range between 58 to 63 percent and the table percentage should range between 55 to 64 percent. The most desired percentages are the 60 percent, and perfectionists will look for depth of 59 through 62 percent and table of 56 through 58 percent.
