Stepped leadhillite crystals with a classic but still very rare blue color, form what seems to be a cast after a now-missing cerussite crystal that would have lent a sharp and organized template for growth of the overlaying leadhillite which might not otherwise be there. From the front, it looks like a single primary leadhillite crystal of shocking size and quality...and indeed, it may be that, if not a cast after cerussite. Either way, its beautiful example of this rare species from one of the most desired locales for leadhillite. I would bet that most people do not have comparable in their collections, certainly, for sheer beauty and for the locality. Ex. Tim Sherburn collection.
