Aquamarine and Morganite belong to the beryl gemstone family. The subtle color in morganite is caused by traces of manganese. Bead-grade aquamarine tends to have many interesting inclusions and numerous opaque areas. The more intense the color, the higher its value. Beryls are hard gemstones, making them an excellent choice for jewelry that will be worn frequently. However, be sure to store aquamarine beads in a dark place, as they often become paler if left out in the sun.
The legendary origin of aquamarine is that it was found in mermaids' treasure chests, making it renowned as a lucky stone for sailors. Its name is derived from the Latin words for "water" and "sea." Consequently, aquamarine is said to protect from perils of the sea, including seasickness. It also is said to heal nerve pain, glandular problems, toothaches and disorders of the neck, jaw and throat. Sources of aquamarine include Brazil, India, Russia, Mozambique, Madagascar, Afghanistan and Pakistan.
