Volcanic PERIDOT / OLIVINE BOMB - Items tagged as "Olivine crystal"

Volcanic olivine bomb.  What makes these specimens extremely interesting is that the interiors of  lava are full of yellow-green colored crystals, a mineral called peridot or olivine from the depth of our earth, thrown out at a volcanic eruption as a volcanic or olivine bomb. This is as close as we can get to samples from the core of our Earth.
