Mt St Helens Helenite (Obsidionite)

“Helenite” is a brilliant green stone created using the volcanic ash and rock dust that resulted from the eruption of Mt St Helens on May 18, 1980.

“Helenite” was discovered accidently when workers using acetylene torches to salvage destroyed equipment discovered that the rock dust was melting and forming a greenish shiny substance. The volcanic rock dust, with heavy concentrations of silica, aluminum and iron with traces of chromium and copper was melting into a form of obsidionite.

Soon, the “Helenite” material was being created using the volcanic rock dust, in a controlled environment. A new jewelry material was available. The brilliant green material is cut and faceted by skilled craftsmen, before being set into 925 silver mountings. The metal is electroplated with Rhodium to resist scratches and tarnish.

The Emerald colored material has excellent sparkle and fair durability. The brilliant green color is the most recognized and appreciated of the possible color variations. We chose to limit our selection to the original Green hues.

“Helenite” jewelry requires simple and regular care. Clean your jewelry with lukewarm soapy water, using a very gentle brush and dry it with a soft cloth. Please do not use ultrasonic cleaners or chemicals.
