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. 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.
Properties include hardness greater than Palladium and Chromium, non-oxidation, melting point of 3567°F, and resistance to most acids and bases. Rhodium electroplating is used-especially on expensive jewelry-to provide a surface that will resist scratches and tarnish, as well as give a white reflective appearance. The product(s) must be return in new unworn condition inside the original packing materials.
