0.49 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This listing describes a single, transparent, round blue sapphire weighing 0.49 carat, an exact weight that positions the gem at the intersection of refined elegance and practical wearability. At just under half a carat, this sapphire offers a concentrated presentation of blue saturation and optical performance, ideally suited for delicate solitaire arrangements or as a central accent in fine jewelry. The stone measures 4.94 by 4.94 by 2.73 millimeters, dimensions that reflect precise cutting and a balance between diameter and depth that preserves face up presence while maintaining stability in a variety of settings. The measured carat weight is a clear indicator of premium quality in stones of this size, as weight at this fraction is most often derived from material that has been carefully selected and proportioned to maximize color and brilliance without unnecessary mass. For collectors and designers who value both measurable specifications and aesthetic potential, the 0.49 carat weight is meaningful because it demonstrates that the pavilion and crown were shaped to deliver optimal light performance rather than to increase weight indiscriminately.

The cutting style is faceted, employing a mixed brilliant cut that combines the best characteristics of step and brilliant faceting to enhance both color dispersion and scintillation. The gem exhibits an overall depth measured at 2.73 millimeters against a diameter of 4.94 millimeters, yielding a depth percentage of approximately 55.3 percent, a proportion commonly associated with balanced light return and sustained color saturation. The mixed brilliant approach provides a lively table reflection and controlled windowing, which allows the vivid blue color to remain concentrated while permitting flashes of brilliance across a range of viewing angles. The polish of this sapphire is graded excellent, a finish that contributes to crisp facet junctions and minimal surface effects, thereby enhancing apparent clarity and maximizing reflective performance. The clarity has been evaluated as slightly included at eye level, a grade that indicates minor natural features which do not materially detract from the stone's overall appearance, and which in many cases serve as confirmation of the natural origin and minimal treatment history of the material.

Color is a principal attribute of this sapphire, and it displays vivid blue intensity that is both saturated and well controlled across the stone's face up presentation. The origin is Ceylon, Sri Lanka, a source known historically and currently for producing sapphires with a lively, saturated blue that often carries a luminous quality distinct from stones of other origins. Enhancement by heat treatment has been disclosed, a conventional and widely accepted process in the trade that stabilizes and enhances color and clarity without undermining the natural corundum structure. When heat treatment is properly applied, it improves hue uniformity and removes or reduces minor inclusions, resulting in a more attractive appearance while preserving the gem's natural identity and origin. In this example the treatment has been performed in a manner consistent with industry standards, and the result is a transparent sapphire with vivid color and an even tone, characteristics that reinforce the gem's premium positioning within its size class.

For practical use and long term appreciation, this 0.49 carat round Ceylon sapphire is well suited to a variety of settings, including classic four or six prong solitaires, low profile bezels for daily wear, and paired accent roles in halo or trilogy configurations. Its compact dimensions and excellent polish make it adaptable to both contemporary and traditional design languages, and the slightly included clarity grade suggests routine care practices such as avoiding aggressive blows and limiting exposure to harsh chemicals, while noting that normal cleaning with warm, soapy water and a soft brush is generally appropriate. The Natural Sapphire Company stands behind the provenance and described characteristics of this gem, and presentation quality including the balanced proportions, vivid color intensity, and refined polish collectively reflect the careful selection criteria applied by our sourcing and grading teams. For customers and designers seeking a premium, measured choice in the sub one carat range, this 0.49 carat round Ceylon sapphire represents a quantifiable and aesthetic option that aligns technical specifications with enduring visual appeal.
