0.87 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This 0.87 carat pear shape blue sapphire from Ceylon Sri Lanka presents a balanced combination of precision cutting and natural character. Measuring 7.50 x 4.48 x 3.36 mm, the gem is fashioned with a mixed brilliant cut and delivers lively scintillation while retaining a pleasing table and pavilion relationship. Clarity is graded as very slightly included when evaluated at eye level, the color intensity is vivid, and the surface shows an excellent polish. The sapphire has been heat treated, a standard and stable enhancement that improves color and clarity without masking the stone’s natural internal features. The Natural Sapphire Company offers this stone for clients who value documented origin and the distinctive visual qualities associated with Sri Lankan material.

The internal features of this sapphire are the defining elements of its signature. Under magnification the stone reveals a fine silk of oriented rutile needles, dispersed in a pattern that softens strong reflections and contributes to the gem’s velvety depth of blue. These rutile needles are complemented by minute mineral crystals and occasional two phase inclusions, small cavities containing both liquid and gas, which are commonly found in natural sapphires and confirm a natural growth history. Subtle growth zoning appears as gentle color banding following the crystal’s growth directions, and healed fissures with reflective veils create tiny mirrored planes that catch and scatter light. Together these inclusions produce an unmistakable fingerprint, a combination of silk texture, discrete crystals, and growth patterns that distinguishes this Ceylon sapphire from stones with more homogenized or synthetic internal characteristics.

Visually, the inclusions enhance rather than detract from the gem’s appeal. The fine silk moderates brilliance to create a saturated, vivid blue that reads consistently across the face of the pear shape, while the mixed brilliant cut maximizes return and flashes without obscuring the stone’s internal story. The very slightly included clarity grade means the inclusions are not intrusive to the naked eye, yet they remain visible under loupe examination and serve as reliable indicators of natural origin. This sapphire’s measured proportions, excellent polish, and natural inclusion pattern make it a suitable choice for refined, everyday jewelry settings where enduring color and natural character are desired.
