There is some misconception about diamond cut, most people refer to diamond shapes as the cut, while it’s not, diamond cut is more about the symmetry, proportioning and polish of a diamond. The most important factor that’s affected by the diamond cut is the brilliance (diamond ability to reflect light), this means if it is cut poorly, it will be less luminous.

Diamond cuts usually comes in 4 known levels (grades) depending on the quality of the diamond: Good, Very Good, Ideal, and Hearts & Arrows (True Hearts in James Allen terminology).

There is a lot of technical stuff to be discussed in diamond cuts, like grading, fancy cuts, round brilliant and the effect of the cut on other Cs, but since most people look for shape rather than the actual cut, we will stop at this point for cut, and go in details about actual diamond shapes.

In the 1400’s diamonds gained popularity in use as jewelry ornaments. During this time various diamond cuts and diamond shapes were developed. In 1919 Marcel Tolkowsky invented the Ideal cut diamond, which quickly became recognized as the standard in round diamonds and the leader for use in diamond engagement rings. Below is a brief review of the most popular diamond shapes used today.

Round cut diamonds

Of these diamonds shapes, the most popular by far is the round diamond, which takes center stage in the classic engagement ring – a round, solitaire diamond set either in yellow gold or platinum. Shapes other than round are called fancy shapes. The most popular different round cut is the Ideal cut diamond which has 58 facets.

Princess cut diamonds

Princess cut diamonds are  the most popular of the fancy shaped diamonds. Princess cut diamonds are relatively new with a shape that is oblong, usually square or almost square, but with a modified brilliant cut arrangement of facets instead of a step cut. Most square or rectangular cuts just don’t live up to the round brilliant for sparkle, but princess cut diamonds are designed for getting maximum brilliance from a square cut.
