TA11E7: I have never before offered Vivianites on my web site. This is because I have always worried that its sensitivity to light and humidity might mean that as time passes a client might have problems with the specimen. In this case I have chosen to add it as both the matrix it sits on, with is absence of sulfides, and the formation where they are found mean that it is very likely to be stable for years to some.
So now that I have added these warnings, I will just point out the perfection, size, and transparency of this one, as well as the fact that it is on matrix. All these factors mean that it would compete with the best examples of this species. A top quality specimen.
