Comment: Hard to find color with a sharper-than-image star. Giant but not too bulky for a men's ring. Facet-quality saturation of Ceylon cornflower blue. Hardly any inclusions. Horizontal and parallel growth lines (see additional pictures) testify to the thousand of years such a crystal needed to grow in ancient times of earth. Though not too sharp, the star is clearly visible, linear and symmetric, even without a strong torch. This color strength is rare in stars.
