This is the definetion of a boulder opal:
precious opal found in ironstone boulders (iron stained sandstone). Scientifically speaking, opals are:
"Tightly packed, regular rows of amorphous silicates (Hydrated Silica (SiOH2o)) that are 5 to 10% water, cut and polished to reflect diffracted light back to the eye." |
