A beautiful, very gemmy, doubly-terminated, pastel blue aquamarine crystal from an unusual locality. Dave Stoudt obtained these while working as a geologist in Argentina in the early 2000's. Other than a very few specimens elsewhere, I have not seen any reach our markets for specimens. And the pieces brought out here, are some of the very best that were obtained by him at the time. 11 grams. Joe Budd photos.
