While probably not to everyone’s taste, this lovely Iolite will certainly appeal to the gemology enthusiasts out there. Rarely do we see a larger clean gem cut to showcase, rather than hide, the dramatic pleochroism of this species. Usually one has to tilt the stone and view through the girdle or at a strong angle to see the grey color - here, however it is framed face-up but the deep blue-violet colors on both sides. Really a fun stone and the presence of the grey really makes the violet hue pop. Excellent US cutting.
