Really a superb crystal - it is flawless; 95% cut-quality. The clarity is like glass, it doesn´t need any light-source to show the color - yu see this wonderful sky-blue to tropical-sea green even when it is lying in a box. All faces show excellent luster and it is a double termianted with razor sharp end-points at bottom and top. Undamaged.
