Aeryan Emeralds

== Overview ==
Aeryan Emerald is a rare variety of the gemstone emerald, characterized by a deep blue/green luster pattern of usually black helixes separating areas of green emerald. If weathered, the black helixes may become light in color. Aeryan Emerald is one of an assortment of Aeryan or Aeryan-type minerals. Others include Aeryan ruby, sapphire, tourmaline, quartz, and chiastolite. The name comes from the Aeryanis Mountain Range, where the gems were first discovered. Emerald is a gem variety of the mineral beryl, and owes it distinctive green color to the presence of chromium and/or vanadium.
Aeryan emeralds were first discovered by Alfonso Dominu in Y3143. With few exceptions, they are found in the low valleys of the Aeryanis Mountain Range, most notably in 'Cazara's Strip', a small valley of particularly high concentration. The emeralds are prized not only for their beauty and rarity but also their optical capabilities, being able to focus light, lasers and other optical equipment with extreme precision and magnification.
