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

This 1.27 carat round faceted bi color parti sapphire from Ceylon Sri Lanka exemplifies precision cutting and natural rarity, The Natural Sapphire Company presents a transparent gem with dimensions 6.48 x 6.46 x 4.02 mm, a mixed brilliant cut and excellent polish. The near perfect round outline indicated by the 6.48 by 6.46 millimeter diameters confirms high symmetry, while the 4.02 millimeter depth yields an approximate depth percentage of 62 percent, a proportion that optimizes light return for mixed brilliant faceting. The cutting style combines a brilliant crown with a pavilion that balances brilliant and step elements, producing strong scintillation and controlled face up dispersion that accentuates the parti color zoning. Clarity is graded very slightly included evaluated at eye level, meaning inclusions are minimal and do not detract from transparency or brilliance under normal viewing, and the absence of any enhancement further elevates the gem from a gemological and investment perspective.

Weight is a critical determinant of value and rarity for sapphires, and at 1.27 carat this piece crosses the important one carat threshold where per carat pricing typically increases nonlinearly, The Natural Sapphire Company notes that availability of high quality, transparent parti sapphires from Ceylon at and above this weight is limited. The 1.27 carat mass affords the cutter sufficient rough to achieve balanced pavilion and crown geometry without compromising table size or color separation, which results in superior light performance and distinct bi color presentation. For the discerning buyer who evaluates both technical attributes and market scarcity, this sapphire offers measurable advantages, combining optimal proportions, excellent polish and natural unheated origin. Recommended use cases include a principal center stone for a refined ring setting where the parti color can be oriented to play with light, or as a collector specimen where weight and natural state contribute to long term desirability.
