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

This transparent, bi color sapphire presents as a precisely faceted emerald cut weighing one point one seven carats. The stone measures six point nine zero by five point five eight by three point zero four millimeters, and carries a clarity grade of very slightly included as evaluated at eye level. The color intensity is described as light, and the gem displays a subtle two tone character that is visible across different facets and viewing angles. The pavilion and crown have been finished to an excellent polish, producing clean facet junctions and a crisp table plane. The sapphire has undergone standard heat treatment to enhance clarity and color stability, and its documented origin is Ceylon, Sri Lanka. This combination of attributes yields a refined, understated appearance that emphasizes transparency and internal character rather than overt saturation.

The emerald cut, with its stepped facets and broad table, defines the gem’s optical personality. Unlike brilliant cuts that fragment light into myriad small flashes, the emerald cut produces larger, more architectural flashes that move across the stone like a series of mirrored planes. This creates a hall of mirrors effect, a rhythmic alternation of light and dark that accentuates the gem’s internal features and the bi color distribution. Because the pavilion angles and step facets are precise, the stone returns light in broader, more continuous flashes which complement its light color intensity. The excellent polish enhances facet contrast and ensures that the transition between color zones remains crisp. The emerald cut also places a premium on clarity, and in this sapphire the very slightly included grading reflects minimal internal features that are not readily visible to the unaided eye, preserving the clean visual field required for this cut to perform at its best.

When compared to more common gemstones and cuts, this Ceylon bi color sapphire offers a distinctive type of brilliance. Round brilliant diamonds and round brilliant cut sapphires are engineered to maximize scintillation through numerous small facets, producing rapid, lively sparkle. By contrast, this emerald cut sapphire emphasizes broad flashes and a linear play of light, rather than dense scintillation. Compared with a typical blue sapphire, which often relies on saturated color and strong pleochroism to command attention, this light bi color example stands out for its subtlety and architectural light behavior. Sapphires in general have a refractive quality that delivers clear light return and crisp facet delineation, and when cut in an emerald shape those traits become more about clarity and directional brightness than about dispersed fire. The result is a gem that reads as elegant and understated, providing a calm luminosity rather than the high intensity sparkle associated with brilliant cuts and with diamonds, and offering a unique visual presence that complements refined settings.

Practical considerations for use and conservation reflect the gem’s combination of cut and origin. The emerald cut’s step facets make it ideally suited for secure bezel or prong settings that protect corners and showcase the table, while the shallow to moderate depth proportion inherent in the listed dimensions supports low profile mounting for everyday wear. Heat treatment, the enhancement applied to this sapphire, is a stable and widely accepted practice within the trade and serves to improve both the stone’s clarity and its tonal balance without compromising durability. Origin information noting Ceylon, Sri Lanka places this stone within a well regarded supply region known for producing sapphires with lively light performance and refined color palettes. For designers and clients seeking a gem that emphasizes internal clarity, linear light patterns, and a subtle duality of tone, this emerald cut bi color sapphire from The Natural Sapphire Company offers a balanced and distinctive option, suitable for bespoke settings where the cut and clarity will be the principal visual narrative.
