Whiteflash ACA Hearts and Arrows diamonds are so special because of the extreme level of cutting expertise that is necessary to produce these elite stones. In addition to having ideal proportions and finish, ACA Hearts and Arrows diamonds also must have perfect 3-Dimensional symmetry (optical symmetry). Optical symmetry is distinct from “meet point” symmetry graded on lab reports which are based upon adjacent facets meeting at consistent points. Optical symmetry is far more difficult for the cutter to achieve, yet critical to ultimate light performance.
Judging the perfection of 3D symmetry is done using a special viewer that produces a detailed view of the hearts and arrows patterning produced by the precise alignment of all the facets in three dimensions. To become a Whiteflash ACA Hearts and Arrows, a diamond must display a perfect pattern in the viewer indicating a level of craftsmanship and light performance at the absolute top limits attainable. Because the perfection of this patterning is crucial to fully analyzing cut quality at this level, we post the Hearts images for all Whiteflash ACA Hearts and Arrows diamonds along with all other quality information about the stone, including Ideal Scope and ASET image, as well as an actual 40x photo of the diamond. If you wish to purchase a true Hearts and Arrows diamond, you should insist on a Hearts image displaying impeccable patterning.
A Whiteflash ACA Hearts and Arrows diamond must first receive 0 ‘Ideal’ grades in light performance, durability, polish & symmetry from the American Gem Society Laboratories. It then must meet our set of published ACA specifications which are a smaller subset of AGS000 parameters. And finally, it must exhibit perfect optical symmetry as demonstrated by true hearts and arrows patterning. The rigorous adherence to all of these standards makes Whiteflash ACA Hearts and Arrows diamond the most proven, verifiable and consistent Super-ideal Cut diamond available on the internet.
Whiteflash was selected to present our Hearts and Arrows grading standards to industry experts at the International Diamond Cut Conference in Moscow in April, 2004. It was our hope that laboratories and peers would make the decision to join us in adopting our demanding standards in the manufacture and marketing of H&A diamonds. At this time Whiteflash.com is the only seller to safeguard consumers with a guarantee of optical symmetry meeting the IDCC presentation criteria.
