11.11 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This exceptional transparent 11.11 carat cushion shape blue sapphire measures 12.53 by 12.15 by 8.36 mm, and its considerable weight is a defining factor in both its aesthetic impact and market value. Weight increases rarity in colored gemstones in a non linear way, and an eleven carat plus sapphire of this quality becomes significantly more scarce and desirable than smaller examples. The mixed brilliant cut maximizes face up brilliance while preserving a substantial table, and the excellent polish enhances light return across the broad face of the gem. The slightly deeper pavilion, at about sixty eight percent depth relative to the average of length and width, helps concentrate color and gives the stone a vivid presence without sacrificing durability for everyday wear. For an educated buyer, the combination of size, cut, and superior polish means this sapphire will perform as a commanding center stone for high jewelry or a museum caliber collection piece.

The gem is unenhanced, having received no enhancement, which markedly elevates its long term value and collector appeal. Its clarity grade is very slightly included evaluated at eye level, indicating that inclusions are minor, contribute little to the stone’s transparency, and do not interrupt the clean blue face up appearance that collectors and connoisseurs prize. The medium intense color intensity is classic for fine Ceylon material, offering a lively, saturated blue with the characteristic brightness and slightly lighter tonal range that distinguishes Sri Lankan sapphires from deeper, denser trade stones. Origin Ceylon, Sri Lanka is noted for producing transparent, crystalline sapphires with excellent lustre, and provenance from this island is an important attribute to discerning buyers who value both beauty and documented origin. At The Natural Sapphire Company we emphasize verified origin and treatment history, and an unheated, eye clean, eleven point eleven carat Ceylon sapphire of this size represents a rare convergence of weight, color, clarity, and craftsmanship. Whether you are seeking a standout engagement center stone, a museum quality investment, or a generational piece of jewelry, this sapphire’s weight and natural presentation make it both a tactile and financial rarity that will appreciate as rarity premiums in the market continue to favor large, untreated fine material.
