Helenite is a gemstone that resulted from volcanic ash and rocks, and is also referred to as emerald obsidianite, Mount St. Helen obsidian. The volcano erupted on May 18, 1980, and ejected igneous rock from 10-20 miles underground. The fury of the volcanic eruption is a wondrous occurrence in nature. The beauty that has been created from it-Helenite is a fantastic thing to hold. Helenite is made by fusing this material at 2700°F, which we facet and polish. The composition of Helenite includes Si-60.50%, Al-16.60%, Fe-6.02%, Ca-5.36%, and other elements.
