"Sunlight coming in from the Academy's central square cast beautiful rays on the massive viewing pane of the Philippine Coral Reef. Solar energy powers the whole reef ecosystem. Algae is eaten by small invertebrates and herbivorous fish which are then eaten by carnivorous which expel nutrients which is then used up by the algae again. It's the circle of reef life!"

Ethiopian opal . Honeycomb pattern. In general, I steer clear of Ethiopian opal due to it being susceptible to clouding and then disintegrating. One piece of this pattern would be nice for my collection.<< Pfff, I know a dragon scale when i see one.
