1.65" Aquamarine Crystal - Brazil

This is a pale blue rough aquamarine crystal, collected from Minas Gerais, Brazil. The state is known for its rich mineral deposits, especially pegmatites containing beryl. Though lacking termination, this specimen still displays excellent faceting and hints of aquamarine's signature sky-blue color.

This specimen 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".
