Personal Note From Natural Gems Belgium:

This particular cabochon exhibits a striking six-ray star pattern caused by intersecting needle-like inclusions. Although inclusions are generally considered flaws in gemstones, in this case they enhance the overall appearance of the stone. The polish and symmetry on one side are graded as good.
