This crystal shows incredible good quality - clarity is like cut glass. The luster of all faces is on highest possible level. I show one photo with a label underneath, there is no minor crack, no bubble, no inclusion - absolutely flawless. The crystal is undamaged, only bottom was extracted from the rock.
