1.02 Ct. Purplish Blue Sapphire from Tanzania

This 1.02 carat cushion shape purplish blue sapphire from Tanzania presents precise dimensions of 6.22 x 4.81 x 3.87 mm, a mixed brilliant cut with a well balanced pavilion to crown ratio, and an excellent polish that produces clean facet junctions and crisp light return. The mixed brilliant faceting combines a faceted crown with kite and star facets and a pavilion that integrates modified brilliant facets to maximize scintillation while preserving depth of color, minimizing windowing and avoiding excessive extinction. Clarity is graded slightly included at eye level, with fine needle and crystal inclusions that do not materially impact transparency or brilliance, instead adding a natural fingerprint that confirms its untreated origin. Color is intense in saturation, registering a primary blue hue with a distinct purple secondary hue, and a medium dark to dark tone that yields strong color presence without appearing inky, the lack of heat or other enhancement allowing the native color zoning and pleochroism to remain visible and to shift subtly as the stone is tilted.

In comparative terms this Tanzanian purplish blue sits between classic Ceylon and Kashmir examples, offering a deeper tone and more pronounced purple influence than many Sri Lankan sapphires, which often show lighter cornflower to violet tinges and higher brightness, yet it lacks the velvety, almost textile like diffusion and purely royal blue character associated with Kashmir material. Compared with Burmese sapphires, which tend toward pure, saturated blue with minimal violet, this stone carries a cooler, more complex color profile due to its purplish component, similar in spirit to certain Madagascan sapphires that can show intense, variable blue violet tones, while differing from Australian material that frequently leans toward darker, greener blues. For designers and connoisseurs The Natural Sapphire Company highlights this stone as an excellent candidate for seated solitaire or halo settings where the mixed brilliant cut will play with light to emphasize both the intense color and lively brilliance, a rare combination in an untreated 1.02 carat cushion that speaks to careful cutting and natural Tanzanian character.
