This is a major, museum-sized specimen with 5 inch brucite crystals, transparent! It is an important piece, of the kind of thing one rarely sees for sale in any size, let alone gigantic. Complete on both sides, this is one of the most displayable old examples I have seen. They were mined in the late 1800s and early 1900s. This one, as you can see, has a long history and was in the prominent collection of EM Gunnell. Although somewhat esoteric to the majority of collectors, I consider these to be prized rarities and major United States classics. For the price, you get one of the best, unarguably, of this species and locality - and the sad fact is one cannot say that about many species' acquisition today. I believe this to be one of the more significant US specimens I have been able to offer, in terms of worldwide or museum import, even if its not as sexy as a tourmaline.
