Design Factors
The original Hearts and Arrows were diamonds that surfaced in the mid 80’s in Japan and embodied three important design factors. First, they were cut to “ideal proportions”, very close to those summarized by Marcel Tolkowsky in his 1919 book, Diamond Design. Second, they were cut with superior physical and optical symmetry so that they would garner a grade of “Excellent” in the Japanese laboratories. The third and very important factor was that they were cut to a very specific brilliantine scheme to produce the accepted hearts and arrows pattern. This faceting scheme involves prescribed lengths and ratios as well as smaller tables sizes that are imperative in producing a distinctive, repeatable and gradable hearts and arrows pattern.
Less than 1% of the world´s rough diamond crystals are pure enough to become a hearts and arrows diamond. Using 100X magnification and analysis through all stages of production, the artisanal cutters create perfection at 10X global standards for grading and evaluation.
A Hearts and Arrows diamond takes up to four times longer to cut than other diamonds.

Famous quotes containing the words design and/or factors:
“To nourish children and raise them against odds is in any time, any place, more valuable than to fix bolts in cars or design nuclear weapons.”
—Marilyn French (20th century)
“Girls tend to attribute their failures to factors such as lack of ability, while boys tend to attribute failure to specific factors, including teachers’ attitudes. Moreover, girls avoid situations in which failure is likely, whereas boys approach such situations as a challenge, indicating that failure differentially affects self-esteem.”
—Michael Lewis (late–20th-century)
