Comments: This specimen came to me in a trade,I have never felt sure that it is the right name although it certainly looks legitimate. It is a great specimen and the xls are perfectly shaped with no blemishes.Whatever its validity it is a beautiful specimen. Perhaps someone may recognise it and let me know.For the crystallographer this is a must own specimen perfectly formed crystals with perfectly formed faces.
