1.14 Ct. Bi Color / Parti Sapphire from Ceylon (Sri Lanka)

This transparent round 1.14 carat bi color or parti sapphire measures 6.74 x 6.67 x 3.62 mm and presents as a classic round faceted gemstone cut in a mixed brilliant style. The stone displays medium color intensity with a subtle interplay of hues that is characteristic of high quality parti sapphires, and its transparency allows both color and light to be seen with clarity. Clarity is graded as very slightly included when evaluated at eye level, which means the inclusions are minimal and do not detract from the overall visual appeal under normal viewing conditions. The polish on this gem is excellent, and crucially it has undergone no enhancement, preserving the natural material and its untreated origin in Ceylon Sri Lanka. These factors together make this sapphire a fine example for collectors and for buyers who prioritize natural provenance and optical purity.

The mixed brilliant cut has been executed to maximize light performance while respecting the stone s natural color zoning. In this example the cutter has employed a traditional brilliant style crown with carefully angled star and kite facets to capture incoming light, combined with a pavilion arrangement that balances depth and reflection to return light through the table. The dimensions produce a depth of about 54 percent relative to the average diameter, which is a proportion that often yields lively brilliance without sacrificing the retention of color. The geometry of the facets creates numerous small planes that act as mirrors, enhancing scintillation and creating flashes of white light and subtle spectral separation that enhance the perceived color contrast within the parti pattern. Because the gem is transparent and unheated, the mixed brilliant faceting allows the natural color patches to flash and shift as the stone moves, offering maximum light play and visual interest for both everyday wear and close inspection by a connoisseur.

From a grading and value perspective, this sapphire combines attributes that educated buyers find desirable. The clarity grade very slightly included suggests that the stone will appear clean to the unaided eye, which supports higher desirability while still reflecting its natural origin. Medium color intensity is an advantage for parti sapphires, as it preserves the distinct color zones without overwhelming the lighter areas, resulting in contrast that reads as lively rather than muddy. Origin from Ceylon Sri Lanka contributes further market value, as Sri Lankan sapphires are historically prized for their color quality and consistent crystal habit, and untreated material from this locale is particularly sought after by collectors and bespoke jewelers. No enhancement is a significant premium factor, as it guarantees that the color and clarity are intrinsic to the crystal, not a result of treatment. The excellent polish and precision of the mixed brilliant cut mean that the gem will perform well in a range of settings, and it is especially well suited to mounts that allow light to enter from multiple angles to exploit the stone s full range of brilliance and color play.
