Emerald Obsidianite, Helenite, and Gaia Stone are all different names for the material created from rock dust (“ash”) blown out of Mt. St. Helens in Washington state when it erupted in 1980. Emerald Obsidianite is not emerald but just as beautiful and much more affordable. Pulverized rock is fused and melted under lab conditions at 2700 degrees Fahrenheit. The green color comes from the trace elements of chromium, copper, and iron.

Peridot is the gem-quality variety of the silicate mineral olivine. Iron inclusions create its light green color. Volcanoes sometimes hurl peridot-rich “bombs,” chunks of hardened basalt containing peridot crystals. Egyptians mined peridot as a gemstone as early as 1580 BCE. Most peridot seen in jewelry today comes from Globe, Arizona. Metaphysically, peridot is used to bring prosperity and to balance moods. Fine specimens of peridot are found in Arizona, Brazil, Pakistan, and Afghanistan.
