1.98 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This 1.98 carat, transparent, GIA certified blue sapphire from Ceylon Sri Lanka is an exceptional example of classic Sri Lankan material, with measurements of 6.97 x 6.96 x 4.59 mm and an asscher octagon shape. The asscher cut in corundum emphasizes depth of color and crisp step facets rather than brilliant scintillation, so clarity and polish are critical. This stone is eye clean at typical viewing distances, which is particularly valuable in a step cut because inclusions are more likely to be visible than in brilliant cuts. The color intensity is described as intense, delivering a vivid saturated blue that is characteristic of fine Ceylon sapphires, and the polish is graded excellent, yielding clean facet junctions and consistent light return. The sapphire has been heat treated, a stable and widely accepted enhancement that improves color uniformity and overall appearance. As with all stones handled by The Natural Sapphire Company, the GIA report provides independent verification of weight, dimensions, shape, clarity, color observations, and treatment status, giving educated buyers confidence in provenance and grading accuracy.

When comparing reflective qualities to other gemstones in its category, consider both gem species and cut. Corundum has a refractive index around 1.76 to 1.77, producing a bright vitreous luster that is less flashy than diamond but more robust and durable for everyday wear than many colored gems. An asscher cut sapphire will display broad, mirror like flashes and an architectural hall of mirrors effect, prioritizing color and clarity, whereas brilliant cut sapphires deliver more scintillation and smaller, lively flashes of light. Compared to spinel, which often shows similar brilliance but minimal pleochroism, this Ceylon sapphire offers richer, layered blue tones and potential pleochroic depth when viewed from different angles. Tanzanite exhibits stronger pleochroism and a softer violet blue shift, but it has a lower refractive index and is softer on the Mohs scale. Diamonds are far more brilliant due to a much higher refractive index, yet they do not provide the same saturated color appeal. For the educated collector seeking a combination of intense Ceylon blue, eye clean clarity, precision asscher faceting, and documented GIA grading, this sapphire from The Natural Sapphire Company represents an investment grade choice that balances aesthetic depth and daily wear durability.
