6.99 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This exceptional transparent 6.99 carat emerald cut shape blue sapphire measures 13.26 x 10.22 x 4.68 millimeters, and it is presented by The Natural Sapphire Company. The stone is faceted in an emerald cut, a step cut that emphasizes the gems transparency and internal clarity through broad, linear facets rather than scintillating brilliancy. With an excellent polish and precise facet junctions the gem displays a clean window through which its color can be appreciated uniformly across the table. The dimensions give this sapphire an elegant rectangular profile that sits comfortably in a wide range of settings, while the depth and table proportions were executed to balance color saturation and light return for a pleasing face up presentation. At 6.99 carats this stone commands presence on the finger while remaining proportional for a classic solitaire or a more architectural bespoke setting, and its faceted emerald cut provides an architectural, refined aesthetic favored by collectors and connoisseurs.

From a grading perspective this sapphire is eye clean as evaluated at eye level, a clarity distinction that markedly increases desirability for transparent sapphires. Eye clean indicates that there are no inclusions visible without magnification to a trained observer under normal viewing conditions, and for step cuts like the emerald cut this quality is particularly important because the larger facets can otherwise reveal internal features. Typical inclusions in corundum include silk, rutile needles, and mineral crystals, and their presence can either detract from or add to a gem in certain circumstances, but an eye clean grade assures an unobstructed field of blue that displays evenly. The color is described as dark intensity, which speaks to the stones tone and saturation. Dark intensity in a high quality sapphire translates to a deep, saturated blue with strong chroma that remains vivid under varied lighting, and this sapphire shows the sort of depth that appeals to buyers seeking a classic, permanent blue. The gem has been heat treated, a common and widely accepted enhancement that improves color uniformity and can reduce the visibility of certain inclusions. Heat treatment is stable and permanent when properly performed, and it is fully disclosed here because transparency about enhancement is fundamental to fair market value and long term satisfaction. The excellent polish and fine facet cutting contribute to a crisp finish that interacts cleanly with light, maximizing the perceived clarity and depth of color.

The origin of this sapphire is Ceylon, Sri Lanka, and that provenance carries significant weight among informed buyers and collectors. Sri Lanka has been a preeminent source of fine sapphires for centuries, and Ceylon stones are prized for their vibrant blues that can range from lively cornflower tones to richer velvety blues, with an optical character often described as lively and well saturated without feeling heavy. Geological conditions in Sri Lanka produce trace element profiles and growth characteristics that frequently result in exceptional color and a pleasing balance between saturation and brightness. Provenance from Ceylon can therefore command a premium because it indicates a heritage of quality and an expectation of certain optical traits. Additionally Ceylon sapphires often exhibit pleochroism and specific internal features that allow gemological laboratories to corroborate origin attribution, providing collectors with an added layer of confidence in the gem s background. For the educated buyer origin is more than a point of romance, it is a factor that informs rarity, market perception, and potential resale value.

Beyond aesthetics and origin this sapphire offers the practical virtues that make corundum a preferred stone for everyday jewelry. Sapphires rank nine on the Mohs hardness scale making them highly resistant to scratches and suitable for daily wear in rings and other frequently worn pieces. The emerald cut, with its step facets and defined edges, tends to emphasize clarity over light scattering which reduces the apparent presence of small surface wear over time when set and protected properly. For those considering this sapphire as an investment or a family heirloom its combination of substantial carat weight, eye clean clarity, dark saturated color, Ceylon origin, excellent polish, and responsible enhancement disclosure make it a well rounded proposition.
