Blue has long been the treasured rare color in this species; gems are almost universally a gray-green or desaturated yellow hue.  These are valued quite highly in Sri Lanka and only see a very few, only 4 stones in the last 10 years if memory serves.  Even then, few stones have been as attractive and distinctly blue as this stone.  Additionally, Fibrolite (the other name for this species) is not particularly easy to cut and so cutting is rarely done as nicely as it is here.  Great color, well cut and a very rare and fine color.
