  • Beryl: The Gem Mineral of Emerald, Aquamarine, Morganite

    The extraction of beryllium from beryl is very costly, and as long as bertrandite is available in large amounts, beryl will be a minor ore of that metal. Small amounts of beryl, mostly produced as a byproduct of gemstone mining, are still used to produce beryllium. The major economic interest in beryl today is its use as a gemstone.
