Here’s a nice “pocket fresh” aquamarine from the Erongo Mountains of Namibia. It has nice color, with a cool blue layer near the top. The back has character, and the bottom has been well recrystallized.
The best feature for me is the rainbows visible down the partially open termination.
It measures 25 x 15 x 14 mm and weighs 7.1 grams
