10.22 Ct. Bi Color Sapphire Crystal from Ceylon (Sri Lanka)

This semi translucent bi color sapphire weighs 10.22 carats and measures 26.41 x 11.63 x 4.96 mm, presented in a various shape that preserves a natural rough crystal character while displaying an excellent polish. The piece shows light color intensity with subtle bi color zoning that is typical of fine Ceylon sapphires, where variations in trace elements and growth conditions produce areas of differing hue. The clarity is graded as very slightly included at eye level, which means the inclusions are minimal and do not detract from overall transparency or visual appeal when viewed without magnification. Enhancement testing confirms no enhancement, a critical distinction for discerning buyers, as untreated sapphires command a premium compared with heat treated material. The rough crystal cut suggests this specimen retains its original form, making it attractive both as a collector specimen and as a candidate for careful faceting or custom design work that can maximize its bi color effect.

For an educated buyer, this sapphire from Ceylon offers multiple points of value, each grounded in gemological fact. The size of 10.22 carats is notable for a bi color stone, providing significant material for cutting or for mounting as a statement gem, and the light color intensity aligns with the classic, sought after Sri Lankan palette that favors elegant, airy blues and soft tones. Clarity graded as very slightly included at eye level indicates excellent visibility and light performance, while the excellent polish will enhance surface luster and perceived brilliance in finished jewelry. The absence of enhancement preserves the stone s natural provenance and makes its color and clarity direct indicators of the original geological conditions. From a market perspective, untreated Ceylon sapphires are preferred by collectors and by designers seeking natural rarity and story, and The Natural Sapphire Company offers this piece with full transparency about origin, treatment, and grading. Whether retained as a museum quality specimen, or transformed into a bespoke ring or pendant that showcases its bi color character, this sapphire provides a compelling balance of provenance, size, and gemological quality for the knowledgeable buyer.
