10.19 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This exceptional cushion shape blue sapphire of 10.19 carats stands as a rare jewel for a select few who understand true scarcity and enduring beauty, and The Natural Sapphire Company is proud to present it to discerning collectors and connoisseurs. At a commanding 10.19 carats this stone immediately moves into a realm of rarity where carat weight becomes the primary storyteller, elevating its presence and its value in ways that smaller stones simply cannot emulate. The gem measures 11.80 by 11.24 by 8.46 millimeters, a substantial face up that reads with confident authority on the finger, in a pendant, or as the centerpiece of a bespoke creation. Cut as a cushion with a mixed brilliant pavilion, and polished to an excellent finish, this sapphire delivers scintillation and depth while retaining the classic, velvety personality associated with fine Ceylon material. The intense color intensity and transparent clarity, described as very slightly included, evaluated at eye level, combine with the weight to produce a stone whose rarity is both visual and technical.

Weight transforms value in colored gemstones, and a 10.19 carat sapphire carries a multiplier effect that magnifies its desirability and price per carat, particularly when accompanied by intense color and eye level clarity. In this sapphire the scale is literal and perceptual, the 10.19 carats allowing for a dramatic face up of 11.80 by 11.24 millimeters, a dimension that reads larger than many stones of lesser mass because of the thoughtful cut and depth of 8.46 millimeters which maintains ideal proportions for light return. The mixed brilliant cut pavilion enhances sparkle while preserving the saturated blue that collectors seek, and the excellent polish ensures each facet interacts with light cleanly, offering crisp flashes and a deep window into the stone. For those who understand gemology, the combination of weight, transparent clarity, and intense color creates a premium profile, one where the cost per carat increases non linearly as carat thresholds are crossed, particularly in the coveted Ceylon origin market.

Provenance and treatment are important to sophisticated buyers, and this sapphire carries the distinguished heritage of Ceylon, Sri Lanka, a source long celebrated for producing blue sapphires with an alluring balance of brilliance and sea like blue. This gem has been heat treated, a standard and stable enhancement that intensifies color while respecting the stone s natural integrity, making it an attractive and reliable choice for high end jewelry. Even with enhancement, a 10.19 carat sapphire exhibiting intense color and very slight inclusions visible only upon careful inspection remains exceptionally rare, and such specimens seldom appear on the market. For collectors and clients who prize uniqueness, the combination of over ten carats, cushion form, mixed brilliant cutting, Ceylon origin, and professional polish creates an opportunity to own a stone that feels almost bespoke at a raw level, as if the world conspired to produce a single exceptional example for the few who can recognize and afford it.
