A helenite necklace carries a piece of volcanic history. This green glass material formed when Mount St. Helens erupted in 1980, fusing ash and rock under intense heat. Our collection features 28,529 helenite pendants set in .925 sterling silver, priced from $16 to $11,402. Each stone displays the deep emerald-green color that helenite produces when volcanic debris reaches temperatures above 1,500°F. Free shipping to all US addresses.

Helenite is a lab-created glass made from volcanic rock and ash collected from Mount St. Helens. The material forms when volcanic debris is heated to extreme temperatures, producing a green glass with consistent color.
Helenite uses natural volcanic material but requires laboratory heating to create the final glass stone. It is classified as a man-made gem created from natural components rather than a mineral that forms in nature.
Clean helenite with warm water and mild soap using a soft cloth. Store separately from harder gemstones to prevent surface scratches, as helenite has a Mohs hardness of 5 to 5.5.
