1.61 Ct. Purplish Blue Sapphire from Tanzania

This transparent cushion shape sapphire weighs 1.61 carat and measures 6.82 x 5.78 x 4.46 mm, cut in a mixed brilliant style that pairs a brilliant facet crown with a faceted pavilion designed to intensify color return. The mixed brilliant cutting approach here prioritizes a lively table and strong face up brilliance while the pavilion geometry deepens tone, resulting in an intense purplish blue that remains uniform across the table and crown facets. Clarity is graded slightly included at eye level, and the stone displays an excellent polish that sharpens facet junctions and enhances contrast between reflective planes. This sapphire is from Tanzania and is supplied by The Natural Sapphire Company as a no enhancement, natural gem, making its color and optical behavior entirely intrinsic to the rough and the cutter s decisions.

What gives this sapphire its unmistakable signature is the suite of internal features and the way they interact with the mixed brilliant facet architecture. Fine silk like rutile dispersion and isolated pinpoint crystals are present, but the most striking characteristic is an oriented crystal cluster and an adjacent small negative crystal cavity that sit near the pavilion edge. These inclusions are cleanly oriented along crystallographic directions, producing guided light scattering and a directional play of color that reads as concentrated purplish blue flashes when the stone is tilted. The silk imparts a slight, desirable softening of highlights that creates a velvety depth, while the crystal cluster acts as an internal facet, generating localized pinfire scintillation and discreet color zoning under oblique light. Together these features produce a signature internal landscape, a combination of depth, pinpoint sparkle, and focused color concentration that is consistent with high quality, natural Tanzanian sapphires and that will read distinctly in mounted settings. For collectors and connoisseurs who value provenance, cutting strategy, and natural inclusion signatures, this sapphire from The Natural Sapphire Company offers a technically refined example of how inclusions can enhance character and visual complexity without compromising polish or color intensity.
