This gemstone tree is made of aquamarine gemstones. The name aquamarine is derived from “water” and “seas”. So it is understandable why some believe it is a lucky stone for sailors preventing seasickness and protecting them from other perils of the sea. Others believed that aquamarine would aid in healing nerve pain, toothaches, glandular problems and disorders of the neck, jaw, and throat. Aquamarine is mined in Afghanistan, Brazil, India, Madagascar, Mozambique, Pakistan and Russia.
