0.63 Ct. Bi Color Sapphire from Ceylon (Sri Lanka)

One transparent zero point six three carat round shape bi color sapphire is presented, measuring five point three nine by five point three seven by three point zero nine millimeters, with a mixed brilliant cut and an excellent polish. The gem is a well balanced round, cut to combine the scintillation of brilliant style facets with faceting that preserves depth and color variation. The clarity grade is very slightly included, evaluated at eye level, which in practical terms means light and unobtrusive natural inclusions that do not interrupt the gems transparency or visual appeal. The stone displays medium light color intensity, and the bi color character manifests as distinct but harmonious zones of hue that change subtly with viewing angle and lighting, creating interest without overwhelming brilliance. No enhancement has been applied, and the sapphire is from Ceylon Sri Lanka, a provenance noted for producing sapphires with lively tone and refined color distribution.

Optical performance emphasizes clean light return and a lively face up appearance, attributes that are amplified by the mixed brilliant cut and precise proportioning of the pavilion and crown. The transparency of this sapphire allows internal light paths to be seen clearly, which highlights the bi color zoning in a controlled and attractive manner. Observed at normal viewing distance the inclusions remain minimal to the unaided eye, preserving a sense of openness and clarity that is desirable for stones of this size and grade. The excellent polish ensures that facet junctions remain crisp and that the surface condition contributes to overall brightness and durability. These combined characteristics make the gem versatile for a range of settings, from solitaire rings that emphasize single stone purity, to accented designs where the bi color quality can be paired with complementary diamonds or colored gemstones.
