In the 1980s, Japanese diamond cutters were the first to produce round brilliant diamonds cut so exactly that their facet reflections overlapped in 3D space, creating kaleidoscopic patterns when seen through reflecting viewers. Usually Excellent-Ideal cuts of superior quality, polishers used "secret recipes" to create the pattern of "Hearts" looking down through the pavilion and "Arrows" seen in the table-up position. The precision and crispness of the patterns relied on precise angles in combination with specific facet length, width and azimuth. Their techniques spread to other cutting houses and Hearts & Arrows diamonds began appearing on several continents by the mid - 1990s.

Symbolism, Hearts & Arrows Viewer

The eight uniform patterns seen in the top and bottom of H&A diamonds have a historical association with good fortune and spiritualism. The number eight is considered lucky in Asian culture. The arrows pattern has been compared to the octagram of the I Ching, the Rinbo of Buddhism and the eight-spoked wheel of Dharma, associated with spiritual perfection in the Buddhist faith. Regardless of spiritual belief, the astonishing achievement of the perfect “hearts and arrows” pattern, painstakingly cut into the world's hardest substance, can be seen by any admirer of structure. In its most fundamental form it symbolizes the diamond cutter's quest for perfection in precision and ultimate beauty in a diamond.

The Hearts & Arrows viewer is a reflecting optical symmetry tool. Looking through it you will see arrows radiating outward in the crown of a H&A diamond.

Turn the diamond over and a circle of hearts appears in the pavilion. The arrows pattern may also be seen in certain lighting or under magnification when mounted but the H&A Viewer is the only tool that reveals hearts patterning. All facets must be precisely aligned to appear correctly. If any part of the diamond is even slightly asymmetric the patterns will be uneven or distorted.
