On its own merits, this is a beautiful display specimen with a nice pastel blue color, and interesting geometry. More than that, this specimen is one of the very best of its rarified style: a strange, splaying and curved, very robust crystal habit that came from a small find in the mid-2000s at this famous locality. I have never seen anhydrite from here, over 25 years, that looked like this. Sure enough, anhydrite is very common here and often single crystals are just sold cheaply as wholesale material, both now and in the past. However, this particular find, this style, I have seen only a handful of fine specimens on the market or in collections - and never cheaply. They stand out from the crowd of literally thousands of other Mexican anhydrites. From the well known Mexico collection of Jason New, which I bought in 2010. I know this seems expensive for anhydrite but...its really very different from the norm, and I think worth the premium to have such a thing. Joe Budd photos
