1.86 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This transparent pear shape blue sapphire weighs 1.86 carat, and measures 9.25 x 5.82 x 4.54 mm, the cutting style is faceted with a mixed brilliant cut, the polish is excellent, and the overall presentation balances brilliance with a refined pavilion depth. The color reads as intense across the table and crown, with lively saturation that remains even through the length of the pear. Clarity is graded as slightly included when evaluated at eye level, a condition that allows the gem to retain clean visual transparency while revealing subtle internal features under closer inspection. The stone is heat treated, a stable and accepted enhancement for sapphires that serves to moderate tone and improve color uniformity, and the material originates from Ceylon Sri Lanka, a source noted for producing sapphires with vivid, crystalline blue tones.

What gives this sapphire its unmistakable signature is the specific suite and arrangement of internal inclusions, a combination that speaks to its natural origin and to the geological history of its formation. Fine silk like rutile needles are present in delicate, parallel groupings, providing a soft internal shimmer that modulates light rather than obstructing it, and isolated pinpoint crystals and tiny reflective mineral crystals punctuate the field, contributing to scintillation when the gem is moved. There are also minute fingerprint style clouds and fine growth zoning lines that follow the gemological growth planes, offering a layered sense of depth that enhances the apparent color from different angles. These inclusions are well distributed and oriented in ways that emphasize the pear shape, creating subtle internal reflections and a velvety depth typical of quality Ceylon material. While some of these features may be perceptible at eye level as noted in the clarity grade, they do not materially compromise the stone's transparency or durability, and they serve as a reliable identifying fingerprint for the specimen. Our gemologists at The Natural Sapphire Company document these characteristics as part of the stone record, and they provide a clear account of how the inclusions influence optical behavior, overall appearance, and identification.
