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

This transparent bi color sapphire from Ceylon, presented by The Natural Sapphire Company, weighs 1.27 carats, and measures 6.48 by 6.46 by 4.02 millimeters, producing an approximate depth of 62 percent, a proportion that balances face up spread with light return. The gem is cut in a round mixed brilliant style, combining a brilliant cut crown with a modified pavilion, a faceting approach chosen to maximize both brilliance and the distinct bi color zoning evident in this stone. The crown facets and table are calibrated to distribute light across the pale yellow and delicate blue zones, while the pavilion faceting preserves weight and contributes to even scintillation. Clarity is graded very slightly included at eye level, meaning inclusions are minimal and do not materially impair transparency or light performance under normal viewing. Color intensity is described as light, and the palette shifts subtly between cool blue and warm yellow depending on orientation, a characteristic highly prized in bi color material. Polish is excellent, evident in crisp facet junctions and clean facet surfaces, and the gem is untreated, no enhancement, a rarity for fine Ceylon sapphires where heat treatment is common.

The 1.27 carat weight is a decisive factor in this sapphires value and desirability, it places the stone above the 1 carat threshold where pricing grids typically increase and where the visual presence on the hand becomes significantly more pronounced. In round stones of these dimensions, each additional tenth of a carat requires the cutter to make careful trade offs between spread and depth, and in this specimen the cutter has retained sufficient depth to maintain optimal optical return while conserving carat weight, a level of craftsmanship that enhances the stones market scarcity. Untreated bi color sapphires from Sri Lanka at this weight are uncommon, which adds a provenance premium for discerning buyers who value natural state material. For collectors and bespoke jewelers seeking a gem that combines measured brilliance, precise faceting, and the rarity of natural color zoning without enhancement, this 1.27 carat Ceylon sapphire represents a technically refined and inherently valuable choice.
