9.15 Ct. Violetish Blue Tanzanite from Tanzania

One transparent tanzanite, cushion shape, weighing 9.15 carats, presents measurements of 14.40 x 10.86 x 6.86 mm, faceted with a mixed brilliant cutting style and an excellent polish. The stone is evaluated as eye clean at normal viewing distance, and it displays a vivid color intensity. These combined attributes, substantial carat weight, generous dimensions, and clarity free of eye visible inclusions, place this specimen in a limited category among faceted tanzanites, where stones approaching 9 carats with such clean material and precise cutting are uncommon. The cutting and polish have been executed to maximize light return while preserving shape and weight, producing an even, lively presentation across the table and pavilion facets.

The color is a distinct violetish blue with vivid saturation, a coloration that is less frequently encountered in larger tanzanite crystals, and therefore contributes significantly to the gem s rarity relative to similar sized material. Heat treated as a standard enhancement to stabilize and intensify the blue violet body color, this gem originates from Tanzania, the sole commercial source historically associated with tanzanite. The combination of substantial size, vivid violetish blue hue, mixed brilliant facet arrangement, and eye clean clarity makes this piece particularly notable for collectors and bespoke jewelry applications where both color and presence are priorities. The Natural Gemstone Company documents the enhancement and origin to ensure transparent provenance, and the stone is presented with factual grading notes so that designers and buyers can assess its suitability for settings that emphasize the gem s color and form.
