Emerald Obsidianite Jewelry You'll find the brilliant green of a Pacific Northwest Rainforest in our Emerald Obsidianite jewelry. These gems were created from material that was blown out of Mt. St. Helens. It was discovered accidentally, when Weyerhaeuser went in to salvage their equipment after the eruption. With acetylene torches, they removed the ugly gray ash that was covering their machinery and noticed it dripping a greenish color. All are sterling silver.
Some styles are available in gold filled for the same price.
