Ring of Fire 

is an area where a large number of earthquakes and volcanic eruptions occur around the basin of the Pacific Ocean. In a 25,000 mile arc, it is associated with a nearly continuous series of oceanic trenches, volcanic belts and tectonic plate movements. The Ring of Fire has 452 volcanoes and is home to over 75% of the world’s active and dormant volcanoes.

Volcanoes are an incubator for many of the world’s treasures. Other gems commonly associated with volcanic origins include Emerald, Diamond, Garnet, Peridot, and Topaz. Hot-water (hydrothermal solutions) that emanate from magmas can crystallize a variety of minerals as the solution moves upward into cooler environments. Metallic ores containing gold, silver, tin, lead, zinc, and copper can originate in this way as can

emeralds and other gems. It is no surprise that Mount St. Helens has proven gold and copper deposits on its flanks. When lava cools quickly, there is no time for mineral crystals to form, and result is volcanic obsidian. When this quench is performed

under controlled lab-conditions it is called “obsidianite.”

 

 

The gems featured in this catalog are called Mount St. Helen Obsidionite. Mount St. Helens Obsidianite is a distant relative to both Lassenite – obsidian from the vicinity of Lassen Peak,

California, and Fire obsidian - iridescent obsidian from Glass Buttes, Oregon. It is also related to Hawaiian Olivine, a light green volcanic stone that can be found on the beaches of Hawaii and is naturally created from the Hawaiian volcanoes.   Olivine is called “Peridot” when found in gemstone quality. Interestingly

enough Olivine and Peridot are the only gemstone found in

meteorites making up as much as 50% of a meteorites

mass and have also been detected on the moon and mars.

 

This striking green stone was created, under conditions of high heat and pressure, from the pulverized rock which came from 15 to 20 miles inside the Earth and expelled by the volcanic eruption from Mount St. Helens, Washington. This beautiful jewelry looks like emerald and is a deep green, brilliant, light catching stone - what you would wish a true Emerald would look like, if you could afford it ! It is truly stunning!   The gemstones that are created today have come from material blown out of the mountain in the 1980’s. Some of the richest colors were from the 1981 and mid-80’s eruptions.   The color of Emerald Obsidianite comes from trace elements that are naturally found in the volcanic rock including chromium, iron and copper that create the rich emerald color when fused at temperatures near 2700 F.

 

 

After the 1980 eruption Weyerhaeuser Timber Company undertook a massive recovery effort to salvage its equipment damaged by the eruption. As workers used acetylene torches to cut apart the twisted metal they noticed the grey ash was melting and turning a greenish color. The pulverized volcanic rock, rich with silica, aluminum and iron with traces of chromium and copper was melting into a form of obsidianite.   Using that information, it was only a matter of time before the first Emerald Obsidianite stones were created. The resulting emerald colored stone has excellent refraction (sparkle) and quartz-like durability. This disaster and chance discovery has left the world with this remarkable legacy of memorable beauty allowing visitors to carry home a beautiful piece of the volcano as jewelry.

 

 

 

Did you know that there are usually several earth quakes & volcanic eruptions every day?   However, many of these are small in scale or in very remote locations and don’t affect humans.
