At nearly an inch wide and 3 inches tall, this is a dramatic aquamarine "single", flanked by two sharp black schorls that make the piece much more aesthetic and interesting than your normal aqua alone might be. The crystal is super gemmy, and it is like a window to look through and see schorls on either side. A fine, complete-all-around small cabinet specimen from recent finds - but unique amongst them.

This is a rare locality specimen of tourmaline, from the Ola Rige of Idaho. It is an extremely good schorl, with high lustre and complete all around. And in fact I would have to say that if I did not know from the label where it was from, because of the quality, I would have assumed it to be from Pakistan or the new finds in Namibia. From the collection of Hubert De Monmonier (1919-2007), donated by bequest to the University of Arizona Museum to add to their displays and to provide specimens for sale to establish an endowment fund for museum operations, in perpetuity.
