2" Aquamarine Crystals on Feldspar - Erongo Mountains, Namibia

This is a gorgeous cluster of gemmy aquamarine crystals on feldspar and iron oxide, collected from the Erongo Mountains of Namibia. The specimen measures 2" wide and the crystals have excellent color and terminations.

It has been mounted to an acrylic display base with mineral tack.

Aquamarine is a blue-green variety of beryl. Oddly enough, it owes its color to iron(II) and iron(III) cations within the crystal lattice, of which iron(II) is responsible for the blue color, while iron(III) is responsible for the yellow color. The color vibrance and hue are dependent on the concentration of these cations, or lack of one or the other. The presence of both cations in the right position within the crystal lattice, can result in a deep blue colored crystal that is known as "maxixe".
