Lava Rock was “created in nature’s own furnace . . . spewed forth in a magnificent display of red boulders, sand and gravel deep within the earth. This rare product comes to us in a way that man has not been able to duplicate.” According to mineralogists at Oregon State University, Lava Rock resulted when steam rose through a volcanic cinder pit after an eruption. Enough silica dissolved in it to deposit opal on the surface of large bubbles that formed before the cinders solidified. Non-precious opal is made of silica, oxygen and water. The ovaline formed before the eruption and is surrounded by the later forming cinder material - the opposite of opal.
