At a glance the material looks like Hydroxyapophyllite yet all the refrence books clearly point out that Inestite was never associated with Hydroxyapophyllite but it is recorded that Inesite was found once with Datolite. 

If this is Datolite the new owner has a bargain - if not it's a exceptional specimen, either way it's a win win. 

Hopefully someone better qualified than are we will be able to shed some more light on the matter?
