Cross' Commitment to Consistency

Cut

Of all the factors, cut has the greatest effect on a diamond's beauty. A Classic Ideal Cut diamond is a fifty-eight facet round diamond adhering to the proportions shown below. It is based on the original calculations done by Marcel Tolkowski in 1919 and published in his book Diamond Design. Tolkowski's work was revolutionary, resulting in the world standard for ideal diamond cutting. Diamonds are graded and valued on the basis of the four C's: cut, color, clarity, and carat weight. Ideal Cut always meant one thing and therefore a cut grade of Ideal represented consistency and a guarantee of matchability.


In August 2005 AGS certification and the soon to follow new GIA certification loosened the standards for the definition of Ideal. These new proportions result in some diamonds which formerly would have received cut grades of 1, 2, 3, now being designated on grading certificates as 0 or Ideal. This radical change in the official meaning of the cut grade means two diamonds of identical color, clarity and weight and both having the designation and certification of Ideal could look markedly different in surface appearance, visual performance and diameter size. See below for common deviations from a Cross Ultimate Ideal Diamond.



Consistency is one of the guiding principles upon which our jewelry store is founded. In spite of this loosening of standards, we will continue to adhere to classic Ideal diamond proportions. The ability to match diamonds at the time of sale, as well as in the future, is essential and will always be among our highest priorities. In addition to breathtaking beauty, matchability is why Cross is committed to the Classic Ideal Cut.
