2.6" Gemmy Aquamarine, Muscovite and Feldspar Association - Pakistan
This gorgeous specimen contains gemmy, sky-blue aquamarine crystals that formed in association with muscovite and feldspar crystals. The largest aquamarine crystal measures 1.8" long and has excellent clarity. It was collected from the mines of Chumar Bakhoor in Pakistan, a location known for its aquamarine crystals. This specimen comes with an acrylic display stand to assist with preferred presentation.
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".
