1.25 Ct. Pinkish Purple Sapphire from Tanzania

This pear shaped pinkish purple sapphire weighs 1.25 carat, and measures 6.88 by 5.71 by 4.03 mm, presenting a compact and wearable footprint with a high face up presence. The crystal is transparent, with an intense color intensity that reads as a saturated pink violet in daylight and warm light, and as a deeper purple under cooler light. Origin is Tanzania, and the material is completely natural, with no enhancement. The Natural Sapphire Company presents this stone as an untreated example of fine corundum, a gem whose inherent optical constants and clean crystal lattice create a foundation for exceptional visual performance. At this size and shape the gem balances presence and practicality, offering enough weight to show complex color dynamics, while retaining the precision of a well executed small gem.

The gem is cut as a mixed brilliant cut, a faceting style that combines the scintillating dynamics of a round brilliant pavilion with a carefully proportioned modified crown and table to flatter the pear outline. The cutter has retained a strong pavilion depth and controlled crown height so that light entering the table is captured by the pavilion facets and returned as bright scintillation and lively flashes rather than lost through an overly windowed face. Facet junctions are sharp and symmetry is controlled to maintain a uniform pattern of light and dark areas, which enhances both flash and contrast. The mixed brilliant approach for a pear shape allows the pavilion to function like a deep brilliant, promoting internal reflection, while the crown facets are shaped to spread color evenly across the face. Excellent polish on all facets ensures mirror like facet planes, reducing light scatter at the surface and maximizing the gem s ability to return light to the viewer.

Optically this sapphire benefits from corundum s intrinsic refractive index and modest dispersion, numbers that underpin its particular type of brilliance and color saturation. Corundum s refractive index in the range of 1.762 to 1.770 raises the critical angle so that with the cut proportions used here a high percentage of incident light is internally reflected and directed back through the crown as scintillation and brilliance. Birefringence is low, about 0.008 to 0.010, which helps maintain sharp facet images and reduces double image effects that can dull small stones, while dispersion around 0.018 supplies subtle spectral flashes when the stone is in motion. The stone displays pleochroism, revealing a secondary pink cast when viewed along certain crystal orientations and a richer violet tone along others, a behavior that a skilled cutter can exploit to present the most desirable color face up. Clarity is graded as very slightly included at eye level, indicating that inclusions are minor and do not impede light travel through the crystal. These inclusions are positioned and oriented so that they do not form windows or dark clouds, instead remaining subordinate to the overall color and brilliance of the gem.

From a craftsmanship and practical perspective this sapphire is ready for elegant setting and daily wear. The pear outline lends itself to both solitaire and halo designs, with the mixed brilliant faceting preserving strong light return when bezel set or prong set. The excellent polish and intact girdle condition make the stone straightforward to set with minimal risk to facet integrity during mounting. The combination of intense color, transparent body, and very slight inclusions results in a gem that photographs well and which will perform consistently in jewelry, maintaining sparkle and saturation. As an untreated Tanzanian sapphire offered by The Natural Sapphire Company this stone will appeal to connoisseurs seeking natural provenance and uncompromised optical character. For clients who value technical detail, this gem demonstrates how color chemistry, refractive behavior, and disciplined cutting practice come together to produce a sparkle that is both lively and characterful, a sparkle that stands apart from stones that have been over cut or altered to modify color.
