2.38 Ct. Bluish Purple Sapphire from Tanzania

This transparent bluish purple sapphire from Tanzania presents as an oval shape weighing 2.38 carats, with dimensions of 8.28 x 6.49 x 5.30 mm. The gem is cut in a mixed brilliant cut, combining a brilliant facet arrangement on the crown with a step influenced pavilion, and it is finished to an excellent polish. The clarity is graded as slightly included when evaluated at eye level, with inclusions that do not dominate the visual presentation. Color is described as intense, a rich bluish purple that is evenly distributed through the stone, and the sapphire is reported as having no enhancement. The Natural Sapphire Company provides this sapphire with documented origin from Tanzania, and the piece is presented for settings that benefit from both proportionate size and a refined, faceted profile.

The exceptional sparkle of this sapphire arises from the intrinsic properties of corundum and from the considered execution of the mixed brilliant cut. Corundum has a relatively high refractive index and modest dispersion, qualities that promote strong internal reflection and crisp return of light to the viewer. In this stone, the brilliant crown facets capture and break incident light into dynamic flashes, while the pavilion facet architecture directs light back through the table and crown, producing pronounced scintillation. The mixed brilliant layout enhances contrast between bright flashes and dark facets, giving movement and life to the intense bluish purple hue without sacrificing depth. Excellent polish on each facet minimizes surface diffusion and preserves sharp facet junctions, which in turn maintains crisp light reflection and crisp return. The slightly included clarity grade indicates small internal features, yet their placement and the stone geometry allow for effective light transmission and play, so the eye perceives a vivid, lively brilliance. Because this sapphire is unenhanced, the optical behavior is native to the material, with trace elements from its Tanzanian origin contributing to the blue to purple tone rather than obscuring it. The result is a gemstone whose structural attributes, precise faceting, and fine finish combine to create a sparkle and presence that stands apart from more routinely cut or treated stones.
