Fast becoming a classic, these are glass clear modified cubes ((cubo-octhedral faces) from the 2004-5 finds at Xinghuapu. By naked eye this is damage free, but with magnification some minor chips can be found, this display well with just a sliver of matrix. This find was prolific and so many good pieces were found that the price was far lower than any other locale. It is now recognized as one of the top discoveries ever made and there is much less of this type to be found on the market. This one has the old price on it, this will be worth far more as the supply dries up.
