BERYL (Aquamarine) BACKGROUND INFORMATION

Beryl (Be3Al2(Si6O18) is a relatively common mineral although it does contain the rare element beryllium. It is most well known however for its gem varieties: the light green to blue aquamarine, the intense green emerald, the yellowish-green to golden heliodor (also known as golden beryl), and the light pink to salmon colored beryl variety knaon as morganite. Beryl also occurs as the colorless gem variety goshenite, and as the very rare red gem beryl variety bixbite.

AQUAMARINE OCCURRENCE AND DIAGNOSTIC FEATURES

Aquamarine crystals (Be3Al2(Si6O18)) occur primarily in granite pegmatites and to a lesser extent in miarolitic cavities in granites, also in hydrothermal carbonate veins and greisens. Aquamarine is typically associated with quartz, albite feldspar, and muscovite, and occurs with other pegmatite accessory minerals such as biotite, smoky quartz, garnet, phenakite and topaz.

Because of aquamarine's relatively high hardness and specific gravity, it is sometimes found in eluvial and aluvial deposits.

The color of aquamarine is due to trace amounts of iron impurities in the beryl structure. The color ranges from pale green to pale blue to blue depending on the relative concentrations of Fe2+ to Fe3+ and on where the iron impurities are located within the beryl crystal structure. The beryl crystal structure contains channels outlined by rings of (Si-O)6 units. These rings are stacked upon each other leaving space within the channels for water or other impurities. Color influencing iron impurities can be present in these interstitial channel sites or substituting for aluminum in octahedral sites. When Fe3+ is present substituting for aluminum in the octahedral site a yellow color is produced. When Fe2+ is present in the interstitial channel site a pure blue color is evident. When both are present the typical blue-green color of fine aquamarine jewelry is produced. Heating a green-blue aquamarine gem to approximately 300 degrees Celcius reduces the Fe3+ to Fe2+, thereby eliminating the yellow and green colors leaving only the pure blue color that is most popular. Irradiation can reverse this process restoring the yellow and green colors.

Aquamarine is usually recognized by its hexagonal form, color and specific gravity. Distinguished from apatite by its greater hardness.
