Abstract: The invention discloses a round or a heart shaped gemstone (FIG. 1) (FIG. 8) visually encompassing a heart shape (FIG. 7,15:AD) within, and its method of manufacture. The gemstone comprises of an upper double crown table facet (A), a lower pavilion (C) with a culet (D) at its lower tip, and a girdle (B) separating the upper crown table facet from the pavilion. The pavilion (FIG. 1) comprises of pavilion main facets, lower girdle facets and short half facets. The short arms (P) of the kite shaped pavilion main facets meet at the culet, long arms (Q) meet at 1st points (R) and the short arms and long arms of each pavilion main facet meet at 2nd points (S) at specific girdle depths. The lower girdle facets (L) and the respective short half facets (T) are faceted from the lower girdle facets at 1st pavilion angles along a cable (R?) joining the 1st points. The 2nd pavilion short half angles (Z) along a cable joining the 2nd points of the pavilion main facets are less than the 1st pavilion angles.

Abstract: The invention discloses a symmetrically cut gemstone of princess cut (FIG. 1) or cushion cut (FIG. 8) which visually encompassing a heart shape (Z1) within and its method of manufacture.
