Abstract

This item is a gemstone with 58 facets, including the culet. The length-to-width ratio of the gemstone is 2:1, which increases the efficiency of light reflection from the pavilion after it enters from the crown. This ratio also emphasizes the gemstone's longitudinal direction, creating the impression of slender, long fingers when worn as a ring. Similarly, when worn as a necklace, the synergistic effect with the collarbone, which extends in the longitudinal direction of the gemstone, creates the impression of a beautiful décolletage. Furthermore, when compared to items of the same mass, the emphasis on the longitudinal direction gives the impression of an enlarged surface area. Combined with the emphasis on the edges of the gemstone due to this ratio, it also gives the impression of a more defined overall outline.
