Hearts and Arrows Zirconiaare precision cut variations of the traditional 57 faceted round brilliant cut. They are cut to “ideal proportions” with superior optical symmetry, polish and a specific faceting pattern. When all these factors are in harmony the result is a repeatable, near perfect pattern of eightsymmetrical arrows in the face up position called 'crown' and eight symmetrical hearts when viewed in the table down position, called 'pavilion'.

There are generally five main components that help to define a "Hearts and Arrows" super-ideal cut diamond. These include a diamond's:

Pavilion angle range

40.2°-41.2°(40.6°-40.8°is optimum)

Crown angle range

33.4°-36.4°(34°-35°is optimum)

Table size range

53% To 58% (54%-57% is optimum)

Lower girdle halves length range

75% To 80% (77% is optimum)

Star facets length range

40% To 58% (45%-50% is optimum)
