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, particularly in Sri Lanka and we only see a very few stones a year. Color is light, but distinctly blue and rare as such. 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.
