2.5" Aquamarine and Quartz in Albite Crystal Matrix - Pakistan

This is a 2.5" wide albite crystal matrix that contains an aquamarine crystal and multiple quartz crystals, collected from Baltistan, Pakistan. The aquamarine has sky-blue coloration towards its termination. A unique characteristic of aquamarine from this location is that it will often fade to a faint magenta color towards its center (beryl var. morganite).

The longest measurement of this aquamarine crystal is .3" wide.

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".

Albite is a plagioclase feldspar mineral with the chemical composition Na(AlSi3O8) when in its pure form. It is a major component of granite and granitic pegmatites, and is often found to form in association with quartz, orthoclase, muscovite, hornblende and biotite. In most cases the crystals will be white to colorless, although it has been known to display red, green and blue hues depending on impurities present during formation. Albite earned its name from the Latin word "albus", meaning white (most commonly found color).

Silicon Dioxide, also known as SiO2 or Quartz, is the second most abundant mineral in the Earth's crust. Quartz crystals generally grow in silica-rich, hot watery solutions called hydrothermal environments, at temperatures between 100°C and 450°C, and usually under very high pressure. Quartz veins are formed when open fissures are filled with hot water during the closing stages of mountains forming, and can be hundreds of millions of years old.
