This extraordinary trillion-cut tanzanite combines two qualities rarely found together in a single gemstone — exceptional depth of colour and remarkable brilliance. This little fire cracker is saturated with rich blue-violet tones, and she  possesses an intense, luxurious colour presence while some how managing to be incredibly lively and full of light. Rather than appearing dark or sleepy, the stone flashes vividly as it moves, with electric blue and rich violet reflections bursting across the facets in a dazzling display. 

Displaying approximately 65% violet and the balance blue, this fine tanzanite showcases the gemstone’s celebrated pleochroism beautifully, with the colours shifting and dancing under different lighting conditions. The precision cutting has been expertly executed to maximize sparkle and light return, allowing the gemstone to glitter with extraordinary life while maintaining its deep, velvety saturation. This stone is also very "moody" and exhibits a fascinating shift between strong blue in white light and then being much more violet in yellow and day light. 

Completely flawless and exceptionally well cut, the facets ignite like tiny fireworks when they catch the light, creating a mesmerizing “hall of mirrors” effect across the surface of the stone. A truly elite tanzanite for collectors who appreciate gemstones with both dramatic colour intensity and exceptional brilliance.

Grades as bV 6/6, AAA+, and “Heirloom Quality” under alternative tanzanite grading systems.
