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 itHeleniteis 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. Rhodium is a precious metal and a member of the platinum family.
