Outstanding bi-color crystal, one of the best of this type I have seen. I have been watching these yellow/blue bi-colors as they have been being found over the past few years and this one would rank as the largest high quality crystal, and one of the top 4 overall. Luster is superb - very glassy. The top 1cm is flawless gem quality and would cut a significant gemstone. Undamaged, with a backside that slopes up to a partial crystal embedded in the backs. Weighs 24.6 grams.
