3.08 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This listing presents a single, transparent blue sapphire weighing 3.08 carats, cut to a classic pear shape with exact dimensions of 13.27 by 7.69 by 3.99 millimeters, offered by The Natural Sapphire Company. The stone exhibits an intense color intensity with a dominant pure blue hue and subtle violet undertones that are characteristic of fine Ceylon origin sapphires. The cutting style is a mixed brilliant cut, engineered to balance scintillation and color saturation, and the surface finish is graded as excellent polish. The clarity has been evaluated as very slightly included at eye level, a designation that communicates minimal visible inclusions to the unaided eye, and the gem has been heat treated, a common and stable enhancement that optimizes tone and clarity while preserving natural origin traits.

Technically the facet architecture follows a mixed brilliant schema, with a brilliant facet pattern on the crown to maximize light return and scintillation, and a complementary faceting arrangement on the pavilion to concentrate color circulation toward the table. The pear outline is proportioned to present an elegant length to width ratio, and the measured depth of 3.99 millimeters corresponds to an approximate depth percentage of 38 percent relative to the mean diameter, indicating a relatively shallow profile that increases face up spread and enhances perceived color saturation. The girdle execution is refined to support secure setting options and the symmetry across the pavilion and crown facets has been adjusted to minimize light leakage, all contributing to an exceptional face up presence and strong table brightness for a colored gem of this size.

From an optical and gemological perspective this sapphire displays the expected physical constants of corundum, with a refractive index typically in the range of 1.762 to 1.770, low birefringence on the order of 0.008, and a specific gravity close to 4.00, factors that influence brilliance, apparent size, and heft. The intense blue coloration is evenly distributed across the table with minor zoning visible under angled viewing, and the stone demonstrates pleochroic behavior that shifts subtly between blue and bluish violet when rotated. Heat treatment in this example has been applied to stabilize and enhance the hue, and to reduce the visibility of fine silk inclusions without compromising structural integrity. The excellent polish underscores clean facet junctions and crisp facet planes, which maximize optical return and improve the apparent depth and saturation of the tone.

Inclusions within this sapphire are best understood as unique identifiers that add character and confirm natural origin, rather than detractors. The very slightly included grading at eye level indicates that inclusions are minimal and generally unobtrusive in normal wear, while under magnification one can expect to observe discrete internal features such as isolated crystal inclusions, minute needle like silk elements, and occasional healed fissures or fingerprint patterns that record the stone history. These microscopic hallmarks serve as a fingerprint, useful for provenance tracking and for distinguishing this natural Ceylon sapphire from synthetic or reconstructed material, and they contribute to the individuality of the gem. For setting considerations, the pear tip benefits from secure protection in a bezel or prong configuration designed to shield the point, and the relatively shallow profile makes this stone ideal for rings that require a low roofline while maintaining a bold face up presentation. The Natural Sapphire Company is available to provide additional detailed imaging, report grade documentation, and consultation on setting options and secure mounting methods, ensuring that the technical qualities and natural character of this 3.08 carat Ceylon pear sapphire are preserved for long term enjoyment.
