WHITEFLASH - AGS Light Performance Map

(HOUSTON, Texas) — NEWS: Whiteflash today announced that they will be providing an Advanced ASET report on all new A CUT ABOVE® hearts and arrows diamonds. The proprietary platinum report from the American Gem Society Laboratories (AGSL) is the most exacting diamond report available and includes comprehensive light performance based cut quality information in the form of grading and graphical light mapping.

Previously the A CUT ABOVE® report included two light maps; a face up map showing light return, contrast and light leakage, and a second pavilion view showing the facet precision of the hearts and arrows patterning. Because the amount and distribution of contrast is so critical to diamond light performance, the new Advanced ASET will add a second face-up light map. Going forward all AGS certificates for A CUT ABOVE® Super ideal diamonds will come with three light maps – face up at 30° and 40°, as well as the pavilion view. The branded AGS A CUT ABOVE® proprietary certificate with Advanced ASET is the most comprehensive diamond document available in the market, and the first diamond report to contain three separate light maps.

Standard platinum reports feature a single face up light map printed at 33.5° of obscuration. This is a compromise between the 30° and 40° that is assessed by the mathematical calculations performed by the computerized ray tracing system pioneered by AGSL. The grading algorithm assesses contrast at both 30 and 40. The default ASET environment is structured at 30 which is the approximate angular range that light is obscured by an observer’s head shadow at normal viewing distances. But if the observer is near sighted and observing the stone at closer than normal distance, head shadow can obstruct closer to 40°.

It is important to know that a diamond does not go dark from obstruction at very close viewing, even as it may perform well at standard viewing distance. The grading algorithm factors 2 parts 30° and 1 part 40°, hence the 33.5° on the standard report. The advanced report will provide the consumer a graphical look at both close and closer viewing distances.
