0.85 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This 0.85 carat round blue sapphire from Ceylon by The Natural Sapphire Company is a superb example of classical gemmological quality combined with natural provenance. The stone measures 5.66 by 5.66 by 3.42 millimeters, and is fashioned in a mixed brilliant cut designed to marry the scintillation of brilliant facets with the color concentration of step facets. Clarity is graded as very slightly included when evaluated at eye level, meaning that minor natural features are present but do not detract from the overall visual appeal to the unaided eye. Color is described as medium intense, a balance of saturation and tone that gives the stone a lively, attractive blue without tipping into overly dark or muted territory. The polish has been executed to an excellent standard, enhancing surface smoothness and light return, and importantly this sapphire shows no enhancement, an attribute that significantly elevates its desirability among collectors and connoisseurs who value untreated natural material.

From a gemological standpoint this sapphire displays attributes that are important to an informed buyer. As a corundum family gemstone, sapphires combine a high refractive index with strong hardness at nine on the Mohs scale, delivering both brilliance and durability for everyday wear. The mixed brilliant cut, combined with the reported dimensions and a depth that translates to a well proportioned round, optimizes both color and light performance, allowing the medium intense blue to present with lively brightness and good face up size for its 0.85 carat weight. The clarity grade very slightly included at eye level is significant because sapphires are commonly host to silk or mineral inclusions, and small inclusions can actually be indicative of natural origin rather than laboratory treatments. In practical terms the inclusions in this stone are subtle, they are not obtrusive in typical viewing conditions, and they do not interfere with the gem's optical performance. The absence of heat or other enhancement is a meaningful market factor, as untreated Ceylon sapphires are comparatively rare and command a premium, offering provenance and aesthetic integrity that educated buyers seek.

The origin of this sapphire, Ceylon, carries deep historical and cultural resonance, and that heritage contributes to its appeal beyond mere aesthetics. Sri Lanka has produced notable sapphires for millennia, supplying gemstones to ancient trade routes and royal treasuries, and Ceylon sapphires have traditionally been prized for their lively medium tones and satiny brilliance. Throughout history such sapphires were often used in regalia and religious ornaments, favored as protective talismans, and valued in astrological traditions where they were believed to bring wisdom and good judgment. Owning a Ceylon sapphire connects the wearer to this long tradition, and an untreated example such as this retains a direct link to those historical associations. For collectors and buyers who appreciate historical continuity, an untreated Sri Lankan sapphire offers both a tangible connection to heritage and an artifact of natural geological processes.

For the educated buyer considering investment, personal adornment, or bespoke commission, this sapphire presents a clear set of advantages. The combination of natural, unenhanced origin, very slightly included clarity at eye level, medium intense color, excellent polish, and balanced proportions offers a gem that is both beautiful and robust. Its size and round mixed brilliant cut make it versatile for classic solitaire rings, vintage inspired settings, or as a refined accent in a bespoke piece, and its hardness makes it suitable for everyday wear when set responsibly. At The Natural Sapphire Company we emphasize full disclosure and careful evaluation, and we can advise on setting options, care, and long term value considerations to ensure this Ceylon sapphire complements both your aesthetic and investment objectives.
